# Trace: Demo Git Hook for Trace ID Integration Agent: claude-code | Model: Claude Opus 4.6 | Project: traces --- ## User I want to investigate adding the installation of a global git hook like git-ai (~/code/git-ai) that allows us to attach a traces id to commits and other refs which will get stored in refs/notes/traces so that the trace id gets synced whne pushed, this way we can automatically read a trace id from a github app and provide more deep and automatic integration, this will be a big feature and may require other changes to the system so lets write a markdown file for this, some follow on pieces: connecting the repo and trace, having the local tui be able to find traces in the current dir if its a git repo, having the traces ui be able to pull down traces that the user did not create, being able to group traces by repo. The overall workflow is that I code with my agent, open a pr, then any other collaborator can browse my trace and even download it locally for inspection (or maybe even resuming in the future, at least injecting as context), so they can understand how i ended up with the PR because the traces provide full context (there may be multiple traces attached to a single pr), this helps with debugging and also attestion of what happened and what tools and data was used. ensure the design has clear boundaries and is in small composbile peieces, there will also need some new api endpoints required to be added ## Assistant ## Assistant Let me explore the codebase first to understand the current architecture and then write the design document. ## Assistant ### Tool: Task **Args:** ```json { "description": "Explore traces codebase architecture", "prompt": "Explore the traces codebase thoroughly.

Let me create a final summary document. ## Traces Codebase Exploration - Complete Summary I've conducted a thorough exploration of the traces codebase. Here's what I found: ### 1. **Project Structure** ``` traces/ ├── api/ # Self-hosted Convex backend ├── cli/ # Bun CLI TUI application ├── frontend/ # Next.js web app ├── packages/shared/ # @traces/shared types └── docs/ # Architecture documentation ``` **Key technologies:** - **Backend**: Self-hosted Convex (HTTP Actions on port 3211, API on 3210) - **CLI**: Bun runtime + OpenTUI + Solid.js + SQLite (better-sqlite3) - **Frontend**: Next.js + React - **Package Manager**: Bun everywhere --- ### 2. **Trace Identification System** Traces use a **dual ID system**: - **`externalId`** (UUID): Generated by the CLI/agent, used as the primary identifier across the system - Used in URLs, API requests, and sync operations - Stable identifier tied to the trace's origin (agent + session) - Example: `"trace-uuid"` - **`traceId`** (Convex ID): Auto-generated by the database - Internal Convex document ID - Used for database relationships - Example: `"convex-trace-id"` **Format**: `externalId` is a string UUID (generated per trace creation), Convex IDs are document references. --- ### 3. **Current API Endpoints** **Sync endpoints** (HTTP Actions at `/v1/traces`): - `POST /v1/traces` - Create trace - `GET /v1/traces` - List traces (most recent first) - `GET /v1/traces/:externalId` - Get trace metadata - `PUT /v1/traces/:externalId` - Update trace metadata - `DELETE /v1/traces/:externalId` - Delete trace - `POST /v1/traces/:externalId/messages/batch` - Batch sync messages - `PUT /v1/traces/:externalId/messages/:messageExternalId` - Upsert single message **Query endpoints** (via Convex query API): - `traces:index` - List public traces - `traces:get` - Get by Convex ID with auth validation - `traces:messagesWithParts` - Get messages with parts - `traces:paginatedMessagesWithParts` - Paginated full trace - `traces:highlightMessagesWithParts` - Filter to highlight messages --- ### 4. **CLI Architecture** **Data Flow:** ``` TUI → SessionController → Session Model → Adapters → Storage (SQLite) ``` **Key Rules:** - TUI only calls `SessionController` (never adapters directly) - Only `SessionController` accesses adapters - `EventStore` is for metadata + sync cache only, NOT detail content - Adapters parse agent storage into `SessionContent` + `SessionEvent` **SQLite Schema:** ```sql traces (id, agent_id, title, preview, timestamp, directory, source_path, shared_url, shared_visibility) events (id, trace_id, event_id, event_json, created_at) -- indexed by trace_id indexes (agent_id, cursor_json, last_scan_at, last_error) -- for incremental discovery ``` **Credentials storage:** - OS config directory (XDG Linux, Application Support macOS, AppData Windows) - Per-server as `credentials-.json` + `device.json` - Separate from SQLite database (supports multiple server URLs) --- ### 5. **Shared Types in `@traces/shared`** **Part Types** (content blocks in messages): ```typescript enum PartType { TEXT = 'text', THINKING = 'thinking', TOOL_CALL = 'tool_call', TOOL_RESULT = 'tool_result', ERROR = 'error', } ``` **Message Structure:** ```typescript interface Message { id: string; role: 'user' | 'assistant' | 'system'; textContent?: string; model?: string; parts: Part[]; // Typed content blocks timestamp: number; order: number; } ``` **Part Content Types:** - `TextContent`: `{ text: string }` - `ThinkingContent`: `{ text: string, durationMs?: number }` - `ToolCallContent`: `{ callId, toolName, args }` - `ToolResultContent`: `{ callId, toolName, output, status }` - `ErrorContent`: `{ message: string }` --- ### 6. **Data Models** **Convex Schema** (3-level hierarchy): ``` traces (metadata layer) └── messages (grouped by role + model) └── parts (typed content blocks) ``` **Trace table fields:** - `externalId` (string, indexed) - `namespaceId` (required after Phase 20 migration) - `createdBy` (user ID) - `visibility` ('private' | 'direct' | 'public') - `agentId`, `title`, `projectPath`, `projectName`, `model` - Cached message counts: `messageCount`, `messageTypeCounts`, `toolTypeCounts` - AI-generated fields: `ai_summary`, `ai_title` **Message table fields:** - `traceId` (FK to traces) - `externalId` (string, indexed) - `role` ('user' | 'assistant' | 'system') - `textContent`, `model`, `order`, `timestamp` - `createdAt`, `updatedAt` **Parts table fields:** - `messageId` (FK to messages) - `type` (one of 5 types) - `content` (typed union matching part type) - `order` (sort order within message) --- ### 7. **CLI-to-API Transformation** **CLI uses events internally** (flat, event-sourced): ```typescript type TraceEvent = | UserMessageEvent | AgentTextEvent | AgentThinkingEvent | ToolCallEvent | ToolResultEvent | ErrorEvent; ``` **API uses messages+parts** (relational): - CLI transforms events → messages at sync boundary - Transformation lives in `cli/src/services/api.ts` - Functions: `buildMessagePayload()`, `syncMessagesBatch()`, `syncTraceMetadata()` **Sync flow:** 1. CLI adapter discovers/parses agent traces → `TraceEvent[]` 2. CLI stores in SQLite as metadata + events 3. On upload, CLI transforms events → `SyncMessagePayload[]` 4. API receives messages + parts, stores in Convex 5. Frontend queries via HTTP or reactive API --- ### 8. **Authentication & Authorization** **Auth model:** - **Users** own identities (device or GitHub) - **Namespaces** are the primary account scope - **Traces** belong to a namespace and have visibility levels - **Membership** defines read/write access **Session types:** - Cookie session (web browser) - CLI device session (persisted token) - Access tokens (reactive queries, short-lived) **Rate limiting:** - `createSession`: 10/min per IP - `authEndpoint`: 30/min per IP - `apiWrite`: 120/min per authenticated user --- ### 9. **How Traces Are Synced** **From CLI to API:** 1. **Metadata sync** (trace creation): ``` POST /v1/traces/:externalId with { agentId, title, projectPath, projectName, model, visibility } ``` 2. **Message sync** (batch or single): ``` POST /v1/traces/:externalId/messages/batch with { messages: [{ externalId, role, textContent, parts: [...] }] } ``` 3. **Idempotent upserts**: Messages are keyed by `(traceId, externalId)` — same message sent twice won't duplicate 4. **Batch sizing**: Messages are chunked respecting `maxBatchBytes` (default) and `maxBatchItems` limits **Internal sync mutation** (`api/convex/internal/sync.ts`): - Verifies write access (user is namespace member or admin) - Creates or updates traces - Upserts messages with parts - Maintains denormalized message type counts - Runs triggers for AI summarization --- ### 10. **Agent Adapters** Supported agents: - `claude-code` (reads from `~/.claude/`) - `cursor` (reads from Cursor workspace storage) - `opencode`, `codex`, `pi`, `amp`, `windsurf`, `copilot`, `gemini-cli`, `manual` **Adapter interface:** ```typescript interface TraceAdapter { id: AgentId; name: string; isAvailable(): Promise; getTraces(options?): Promise; getTraceContent(trace): Promise; // Returns all events subscribe(trace, onEvent): Promise<() => void>; // Live updates count(trace): Promise; // Lightweight getTraceIndexBatch?(options?): Promise; // Incremental getVersion(): string; } ``` **Claude Code adapter specifics:** - Reads from `~/.claude/history.jsonl` (tail-first for recent sessions) - Scans `~/.claude/projects/` for individual session files - Caches sessionId → sourcePath mappings (bounded to 500) - Adaptive history scan: starts 2MB, grows up to 32MB - Includes discovery diagnostics reporting to Sentry --- ### 11. **Key Files and Locations** **API**: - `/api/convex/schema.ts` - Database schema definition - `/api/convex/traces.ts` - Trace query functions - `/api/convex/http/v1/traces.ts` - HTTP endpoints - `/api/convex/services/traces.ts` - Service layer (auth, mapping) - `/api/convex/services/messages.ts` - Message/part sync - `/api/convex/internal/sync.ts` - Internal sync mutations - `/api/convex/models.ts` - Model registry queries **CLI**: - `/cli/src/core/event-store.ts` - SQLite storage layer - `/cli/src/core/trace-controller.ts` - Main controller - `/cli/src/core/trace.ts` - Trace model - `/cli/src/services/api.ts` - Convex API client + transformation - `/cli/src/adapters/` - Agent adapters - `/cli/src/adapters/adapter.ts` - Base adapter interface - `/cli/src/types.ts` - CLI-specific event types **Shared**: - `/packages/shared/src/part.ts` - Part type definitions - `/packages/shared/src/message.ts` - Message type - `/packages/shared/src/trace.ts` - Trace metadata - `/packages/shared/src/schemas/` - Zod validators --- ### 12. **Memory Management Rules (CLI)** The CLI is a long-lived TUI process. Key rules to prevent unbounded growth: - MUST: Override `count()` on adapters — default loads full content - MUST: Use `lastEventCount` integer, not `Set` for subscriptions - MUST: Check file mtime before re-reads in polling - MUST: Call `closeDetailView()` (not manual resets) when leaving detail - MUST: Bound in-memory caches (Maps, Sets) with LRU eviction - NEVER: Store raw request/response bodies — truncate to string - NEVER: Copy stale Map entries across refresh cycles without pruning Memory monitoring: Sentry gauges every 60s (`cli.memory.*`), warnings at 512MB, critical at 1GB. --- ### 13. **Event vs Message Distinction** | Aspect | CLI (Events) | API (Messages+Parts) | |--------|-------------|---------------------| | **Model** | Event-sourced (flat) | Relational (grouped) | | **Storage** | `events` table | `messages` + `parts` tables | | **Why** | Matches adapter parsing (line-by-line), preserves exact order | Normalizes for frontend display | | **Transform** | At sync boundary (`api.ts`) | CLI builds `SyncMessagePayload` | --- This comprehensive exploration covers the architecture, data models, API contracts, storage mechanisms, and key design decisions throughout the traces system. The platform follows clear separation of concerns: CLI captures and transforms, API stores and serves, frontend displays. agentId: a5fd575d754b39c66 (for resuming to continue this agent's work if needed) total_tokens: 75883 tool_uses: 43 duration_ms: 70239 ``` ## Assistant ### Tool: Task **Args:** ```json { "description": "Explore git-ai repo structure", "prompt": "Explore the git-ai repository at ~/code/git-ai.

Let me compile a comprehensive summary of git-ai. ## Summary: Git-AI Repository Exploration I've thoroughly explored the git-ai repository. Here's a comprehensive understanding of what it is, how it works, and its architecture: ### 1. **What is git-ai?** Git-AI is an open-source git extension that tracks AI-generated code in git repositories. It automatically links every AI-written line to the agent (Cursor, Claude Code, Copilot, etc.), model, and conversation transcript that generated it. This preserves the "why" behind code—the intent, requirements, and architecture decisions—so developers can understand the original context even months later. Key philosophy: **No workflow changes needed.** Just prompt and commit as normal. Git-AI tracks attribution automatically without cluttering git history. ### 2. **Installation (Global Git Hook Mechanism)** **Install script:** `/Users/andrew/code/git-ai/install.sh` (bash) and `install.ps1` (PowerShell for Windows) The installation process: - Downloads the git-ai binary for your OS/architecture (x64 or arm64) - Verifies SHA256 checksums - Creates `~/.git-ai/` config directory - Detects and patches shell config files (`.bashrc`, `.zshrc`, `.config/fish/config.fish`) - **Symlinks** the git-ai binary as `git` in a directory early on PATH (`~/.git-ai/bin/`) - Installs agent hooks into IDE/editor configs (Cursor, Claude Code, VS Code, etc.) - Installs the `/ask` skill into `~/.agents/skills/` and `~/.claude/skills/` The binary dispatch is **based on `argv[0]`**: - When invoked as `git` → acts as a transparent git proxy with pre/post hooks - When invoked as `git-ai` → handles subcommands (blame, diff, status, checkpoint, etc.) - In debug mode with `GIT_AI=git` env var → forces git proxy mode **Global hook approach:** The binary installation in PATH + symlink strategy means git-ai intercepts all git commands globally without needing per-repository setup. ### 3. **Hooks Installed and Their Functions** Git-AI installs pre/post hooks for these git subcommands (in `/src/commands/hooks/`): | Hook | Purpose | |------|---------| | **commit** | Pre: captures virtual attributions from working log. Post: generates authorship note attached to commit | | **rebase** | Pre: records original HEAD/onto. Post: rewrites authorship notes to follow commits through rebases | | **cherry-pick** | Post: copies/adapts authorship from source commit to new commit | | **reset** | Post: reconstructs working logs when commits are un-done (moves authorship back to working state) | | **stash** | Preserves uncommitted AI attributions across stash/pop operations | | **merge** | Post: handles conflict resolution attribution. Merge --squash moves attributions to working state | | **clone** | Post: fetches authorship notes from origin repository | | **fetch/push** | Background threads sync authorship notes with remote | | **checkout/switch** | Ensures clean working log state transitions | **Hook mechanics:** Each hook is a Rust function that: 1. Parses the git command arguments 2. Runs git's built-in behavior 3. Processes authorship data based on what changed 4. Attaches notes to affected commits On Unix, signal handlers (SIGTERM, SIGINT, SIGHUP, SIGQUIT) are installed to forward signals from git-ai to the child git process. ### 4. **How It Attaches Metadata to Commits** **Working log + Checkpoints → Authorship Log → Git Notes** The flow: 1. **Checkpoint:** When an AI agent finishes editing, it calls `git-ai checkpoint ` with: - Hook input (JSON on stdin) containing edited files, model, transcript - Agent ID: `{tool}:{model}:{session_id}` - Timestamp 2. **Working Log:** Checkpoint data is written to `.git/ai/working_logs//` as JSON files - Records per-file line attributions (which ranges are AI vs human) - Includes prompt metadata (transcript, model, agent info) 3. **Virtual Attributions:** On commit, the system creates a `VirtualAttributions` object by: - Reading all working log entries from the current base commit - Running a diff to compute character-level → line-level attributions - Determining which lines were AI-generated vs human-authored 4. **Authorship Log:** The post-commit hook generates an `AuthorshipLog` that contains: - **Attestation section:** File-by-file mapping of session hash → line ranges - **Metadata section:** JSON with prompts, agent info, model, transcript 5. **Git Note:** The authorship log is attached to the commit via `git notes --ref=ai add` ### 5. **Git Notes Usage** **Git Notes Store Authorship Data:** - **Namespace:** `refs/notes/ai` (not the default `refs/notes/commits` to avoid conflicts) - **Format:** Custom text format (authorship/3.0.0 schema) - **Structure:** ``` src/main.rs a1b2c3d4e5f6a7b8 1-10,15-20 c9d0e1f2a3b4c5d6 25,30-35 --- { "schema_version": "authorship/3.0.0", "git_ai_version": "1.0.24", "base_commit_sha": "7734793b756b3921...", "prompts": { "a1b2c3d4e5f6a7b8": { "agent_id": {"tool": "cursor", "id": "...", "model": "..."}, "human_author": "Alice ", "messages": [...transcript...], "total_additions": 25, "total_deletions": 5, "accepted_lines": 20, "overriden_lines": 0 } } } ``` - **Attestation section:** Fast-lookup plain text before `---` divider - **Metadata section:** JSON below divider with full transcript and stats - **Session hash:** SHA-256 of `{tool}:{conversation_id}`, taking first 16 hex chars - **Push refspec:** `refs/notes/ai:refs/notes/ai` (syncs notes to remote) - **Stash notes:** Uses `refs/notes/ai-stash` for temporary working state **Key advantage:** Git notes are not part of commit content, so they don't affect commit SHAs. Rebases, amends, and other history rewrites don't invalidate the commits themselves. ### 6. **Overall Architecture** ``` User commits code (AI-generated via agent) ↓ ┌─────────────────────────────────┐ │ git-ai proxy intercepts "git" │ └─────────────────────────────────┘ ↓ ┌─────────────────────────────────┐ │ Pre-commit hook │ │ - Reads .git/ai/working_logs/ │ │ - Captures virtual attributions │ └─────────────────────────────────┘ ↓ ┌─────────────────────────────────┐ │ Real git commit executes │ └─────────────────────────────────┘ ↓ ┌─────────────────────────────────┐ │ Post-commit hook │ │ - Generates AuthorshipLog │ │ - Attaches to commit via │ │ refs/notes/ai │ │ - Stores transcript in SQLite │ │ - Clears working log │ └─────────────────────────────────┘ ↓ [Commit with attached note] ``` **Git rewrite scenarios (rebase, cherry-pick, reset, amend, merge):** - Rebase: Authorship logs copied to new commits, line numbers recalculated - Squash: Prompt records from all squashed commits preserved - Reset/Cherry-pick: Attributions moved from committed logs to working state - Stash/Pop: Attributions saved in `refs/notes/ai-stash`, restored on pop - Merge --squash: AI attributions moved to working log for next commit **Key files:** - `/src/main.rs` — Binary dispatch by `argv[0]` - `/src/commands/git_handlers.rs` — Git proxy + hook execution - `/src/commands/git_hook_handlers.rs` — Per-subcommand hook orchestration - `/src/commands/hooks/` — Individual hook implementations - `/src/authorship/` — Attribution tracking, working logs, authorship logs - `post_commit.rs` — Generates authorship notes - `authorship_log_serialization.rs` — Serializes to v3.0.0 format - `working_log.rs` — In-memory checkpoint tracking - `attribution_tracker.rs` — Line-by-line attribution computation - `rebase_authorship.rs` — History rewrite handling (largest file, 155K) - `/src/git/refs.rs` — Git notes operations - `/src/mdm/` — Installer infrastructure (agents, hooks, skills) **Supported agents:** Claude Code, Cursor, Codex, OpenCode, Gemini, GitHub Copilot, Continue, Droid, Junie, Rovo Dev **Test infrastructure:** - Integration tests in `/tests/` create real git repos via `git2` crate - `TestRepo` fluent API with `.ai()` / `.human()` line attribution - Snapshot tests via `insta` crate - E2E tests via `bats` shell framework - Test-only `--features test-support` enables `git2` dependency **Configuration:** - Global config: `~/.git-ai/config.json` - Feature flags (rewrite_stash, inter_commit_move, auth_keyring) - Prompt storage modes: Local (SQLite only), Notes (in git), Cloud - Optional secret redaction and PII filtering This architecture achieves zero workflow disruption while providing complete AI attribution tracking across all git operations. agentId: aa06bc4fb1ce0c0c4 (for resuming to continue this agent's work if needed) total_tokens: 74009 tool_uses: 31 duration_ms: 63085 ``` ## Assistant ## Assistant Now I have a thorough understanding of both codebases. Let me write the design document. ## Assistant ### Tool: Write **Args:** ```json { "content": "# Git Integration\n\nAttach trace IDs to git commits so collaborators can browse the full agent context behind any PR.\n\n## The problem\n\nWhen someone opens a PR that was built with an AI agent, reviewers see the code but not the conversation that produced it. They can't tell which decisions were intentional, which were the agent's suggestion, or what alternatives were considered. The trace is the missing context.\n\n## How it works\n\nA global git hook writes trace IDs into git notes on each commit. When pushed, the notes travel with the commits. A GitHub App reads those notes and links traces to PRs. Any collaborator with access to the repo can then view the traces that produced the code.\n\n```\ndeveloper codes with agent\n ↓\ntraces CLI records the session (existing behavior)\n ↓\ngit hook writes trace external ID into refs/notes/traces on commit\n ↓\ngit push syncs notes to remote\n ↓\nGitHub App reads notes, links traces to PR\n ↓\ncollaborators browse traces from PR\n```\n\nMultiple traces can attach to a single commit (agent restarts, multiple sessions) and multiple commits can reference the same trace (long session spanning several commits).\n\n## Design pieces\n\nEach piece is independently useful and can ship separately.\n\n### Piece 1: Git hook that writes trace IDs to notes\n\nA post-commit hook that finds active traces for the current working directory and writes their external IDs into `refs/notes/traces` on the new commit.\n\n**Note format** (one trace ID per line):\n\n```\ntraces:\ntraces:\n```\n\nPlain text, one entry per line. The `traces:` prefix prevents collision if other tools use git notes on the same ref. Additional metadata can be added later as `key:value` lines without breaking parsers.\n\n**How the hook finds active traces:**\n\nThe hook needs to know which trace IDs are active for the current directory. Two options, in order of preference:\n\n1. **Marker file**: The traces CLI writes `.git/traces-active` containing current trace external IDs (one per line) whenever a trace is being recorded in that directory. The hook reads this file. Simple, no IPC, works offline.\n2. **CLI query**: The hook shells out to `traces active --dir .` which queries the SQLite database for traces whose `directory` matches the current repo root.\n\nThe marker file approach is better because it has zero dependencies on the CLI being installed or running. The CLI manages the file lifecycle: writes it when recording starts, appends additional IDs if multiple traces are active, removes stale entries when traces end.\n\n**Integration with git-ai:**\n\nThis can be a standalone hook or integrate with git-ai's hook infrastructure. git-ai already intercepts post-commit and manages `refs/notes/ai`. The traces hook would use a separate ref (`refs/notes/traces`) to keep concerns separated. If git-ai is present, it could call the traces hook as part of its post-commit chain. If not, a standalone post-commit hook handles it.\n\n**Push/fetch sync:**\n\nGit notes don't sync by default. The hook (or a post-push hook) needs to add the refspec:\n\n```\ngit push origin refs/notes/traces:refs/notes/traces\n```\n\nSame for fetch. This can be configured once per repo via:\n\n```\ngit config --add remote.origin.fetch '+refs/notes/traces:refs/notes/traces'\ngit config --add remote.origin.push 'refs/notes/traces:refs/notes/traces'\n```\n\nThe hook installer should set this up automatically.\n\n### Piece 2: CLI writes active trace markers\n\nWhen the traces CLI starts recording a trace in a directory that's a git repo, it writes the trace's external ID to `.git/traces-active`. When recording stops, it removes that ID.\n\nChanges to `cli/`:\n\n- On trace recording start: detect if `directory` is inside a git repo, find the `.git` dir, write/append to `.git/traces-active`\n- On trace recording stop (or process exit): remove the trace ID from the file\n- Handle cleanup on crash (stale entries get cleaned up on next start, or the hook can check if the trace is still alive)\n\nAdd `.git/traces-active` to a suggested `.gitignore` entry (it's inside `.git/` so it's already ignored by git, but worth noting).\n\n### Piece 3: Repo identity and linking\n\nTo connect a git repo to a traces namespace, we need a stable repo identifier. The remote URL is the natural choice, normalized to strip auth tokens and `.git` suffixes.\n\n**New concept: `repo`**\n\nA repo record ties a git remote URL to a traces namespace. This enables:\n\n- Looking up traces by repo\n- Grouping traces under a repo in the UI\n- GitHub App knowing which namespace to query\n\n**New Convex table: `repos`**\n\n```\nrepos\n namespaceId: Id<\"namespaces\">\n remoteUrl: string // normalized, e.g. \"github.com/org/repo\"\n provider: string // \"github\" | \"gitlab\" | etc.\n providerRepoId: string // GitHub's numeric repo ID (stable across renames)\n name: string // \"org/repo\"\n createdBy: Id<\"users\">\n createdAt: number\n```\n\nIndex on `(namespaceId, remoteUrl)` and `(provider, providerRepoId)`.\n\n**New Convex table: `traceRepoLinks`**\n\n```\ntraceRepoLinks\n traceId: Id<\"traces\">\n repoId: Id<\"repos\">\n commitShas: string[] // commits where this trace was referenced\n createdAt: number\n```\n\nIndex on `(repoId)` and `(traceId)`.\n\nThis is a separate link table rather than a field on the trace because one trace can span multiple repos (rare but possible) and one commit can reference multiple traces. The `commitShas` array tracks which specific commits referenced the trace, useful for mapping traces to PRs.\n\n### Piece 4: API endpoints for git integration\n\nNew HTTP endpoints under `/v1/`:\n\n**Repo management:**\n\n```\nPOST /v1/repos # Register a repo in a namespace\nGET /v1/repos?namespaceId=... # List repos for a namespace\nGET /v1/repos/:repoId # Get repo details\n```\n\n**Trace-repo linking:**\n\n```\nPOST /v1/repos/:repoId/traces # Link a trace to a repo + commit\nGET /v1/repos/:repoId/traces # List traces linked to a repo\nGET /v1/repos/:repoId/traces?commit=SHA # Traces for a specific commit\nGET /v1/repos/:repoId/traces?pr=123 # Traces for commits in a PR\n```\n\n**Trace lookup by commit (used by GitHub App):**\n\n```\nGET /v1/lookup/commit/:sha # Find traces referencing this commit\nGET /v1/lookup/repo/:provider/:owner/:name/traces # Traces for a repo by name\n```\n\n**Auth for these endpoints:**\n\n- Repo management: requires namespace membership (existing auth)\n- Trace-repo linking: requires write access to the namespace\n- Trace lookup: respects trace visibility. Public traces visible to anyone, private traces require namespace membership\n- GitHub App: uses an API key issued per-namespace for the app installation\n\n### Piece 5: CLI push hook syncs trace-repo links\n\nAfter `git push`, a post-push hook (or the push hook itself) reads `refs/notes/traces` for pushed commits and calls the API to register the links.\n\n```\nfor each pushed commit:\n read git notes for refs/notes/traces\n parse trace IDs\n POST /v1/repos/:repoId/traces with { traceExternalId, commitSha }\n```\n\nThis is idempotent. Pushing the same commits again won't create duplicates.\n\nThe hook needs to know the repo ID. It can look this up once and cache it:\n\n```\nPOST /v1/repos with { remoteUrl, namespaceId }\n→ returns repoId (or existing if already registered)\n```\n\nCache the repo ID in `.git/traces-repo-id`.\n\n### Piece 6: CLI discovers traces by git repo\n\nWhen the CLI is run inside a git repo, it can show traces associated with that repo, not just locally-discovered ones.\n\nChanges to `cli/`:\n\n- New source of traces: API query by repo remote URL\n- `traces list` gains a `--repo` flag (defaults to current git repo if in one)\n- The trace list view shows both local traces and remote traces linked to this repo\n- Remote traces are clearly labeled as such (different icon or tag)\n\nThis lets a developer clone a repo and immediately see what traces exist for it, even traces from other contributors.\n\n### Piece 7: GitHub App reads notes, shows traces on PRs\n\nA GitHub App that installs on repos and adds trace context to PRs.\n\n**On PR open/update:**\n\n1. List commits in the PR\n2. For each commit, query `GET /v1/lookup/commit/:sha`\n3. Collect all referenced traces\n4. Post a PR comment (or check run summary) with links to the traces\n\n**Comment format:**\n\n```markdown\n### Traces\n\nThis PR includes 3 agent traces:\n\n- [Add authentication middleware](https://traces.example.com/t/abc123) by @alice using Claude Sonnet - 47 messages\n- [Fix token refresh](https://traces.example.com/t/def456) by @alice using Claude Sonnet - 12 messages\n- [Add tests](https://traces.example.com/t/ghi789) by @bob using Cursor - 23 messages\n```\n\nThe comment updates as new commits are pushed to the PR.\n\n**Installation flow:**\n\n1. User installs the GitHub App on their repo/org\n2. App requests the namespace's API key (stored as app config)\n3. App listens for PR webhooks\n4. App queries the traces API using the namespace API key\n\nThis piece depends on pieces 3, 4, and 5. It also needs a way to issue API keys per namespace, which is a new auth concept.\n\n### Piece 8: Frontend shows repo-grouped traces\n\nThe frontend gains a repo view that groups traces by repository.\n\n- Repo page: shows all traces linked to a repo, filterable by contributor, date, branch\n- PR view: shows traces linked to a specific PR's commits\n- Trace detail page: shows which commits/PRs reference this trace\n\nNavigation: Namespace → Repos → Traces (or the existing flat trace list, which remains)\n\n### Piece 9: Trace export and download\n\nCollaborators can download a trace for local inspection.\n\n**New API endpoint:**\n\n```\nGET /v1/traces/:externalId/export # Full trace as JSON\n```\n\nReturns the complete trace with all messages and parts in a portable format. The CLI can import this:\n\n```\ntraces import \ntraces import \n```\n\nThe imported trace appears in the local TUI with a badge indicating it's imported, not locally generated. This enables offline review and future features like injecting trace context into new agent sessions.\n\n## Ordering and dependencies\n\n```\nPiece 1 (git hook) ← standalone, works without API\nPiece 2 (CLI markers) ← standalone, enables piece 1\nPiece 3 (repo identity) ← API schema work\nPiece 4 (API endpoints) ← depends on 3\nPiece 5 (push hook sync) ← depends on 1, 3, 4\nPiece 6 (CLI repo lookup) ← depends on 4\nPiece 7 (GitHub App) ← depends on 4, 5\nPiece 8 (frontend repo view)← depends on 3, 4\nPiece 9 (trace export) ← mostly independent, depends on 4 for the endpoint\n```\n\nPieces 1 and 2 can ship first with zero API changes. A developer gets trace IDs in their git notes immediately, viewable with `git notes --ref=traces show HEAD`. The API integration layers on top.\n\n## Open questions\n\n**Note ref naming**: `refs/notes/traces` is clean but could conflict if another tool picks the same name. `refs/notes/traces-dev` or including a domain (`refs/notes/traces.dev`) would be more defensive.\n\n**Multiple namespaces**: A single repo could be linked to multiple namespaces if different team members use different traces accounts. The repo table handles this (one row per namespace+remoteUrl pair), but the GitHub App needs to know which namespace to query. This likely means the app installation is scoped to a namespace.\n\n**Note vs trailer**: An alternative to git notes is commit message trailers (`Traces-Id: abc123`). Trailers are more visible and survive all history operations natively, but they pollute commit messages and can't be added after the fact. Git notes are the right choice for metadata that should travel with commits without being part of the commit itself.\n\n**Privacy**: Traces may contain sensitive conversation content. The visibility model (private/direct/public) already handles access control, but users should understand that linking a trace to a repo makes it discoverable by namespace members. A confirmation prompt on first link might be appropriate.\n\n**git-ai coordination**: If the user has git-ai installed, both tools write notes on commit. They use separate refs (`refs/notes/ai` vs `refs/notes/traces`) so they don't conflict, but the push refspec configuration needs to handle both. git-ai already manages push refspecs, so an integration point where git-ai knows about traces' ref would avoid duplicate configuration.\n", "file_path": "/Users/andrew/code/traces/traces/docs/git-integration.md" } ``` ## Assistant **Result** (success): ``` File created successfully at: /Users/andrew/code/traces/traces/docs/git-integration.md ``` ## Assistant Written to `docs/git-integration.md`. Here's the shape of it: **9 composable pieces**, each independently shippable: 1. **Git hook** that writes trace external IDs into `refs/notes/traces` on commit 2. **CLI marker files** (`.git/traces-active`) so the hook knows which traces are recording 3. **Repo identity** -- new `repos` and `traceRepoLinks` Convex tables to connect git repos to namespaces 4. **API endpoints** for repo management, trace-repo linking, and commit-based lookup 5. **Push hook** that syncs trace-repo links to the API after push 6. **CLI repo-aware trace discovery** -- run traces inside a cloned repo, see everyone's traces for it 7. **GitHub App** that reads notes on PR commits and posts trace links as comments 8. **Frontend repo view** -- group and browse traces by repository 9. **Trace export/import** -- download traces for local inspection or context injection Pieces 1 and 2 are pure local git work with zero API changes and can ship first. The rest layers on in dependency order. The doc covers the note format, how it coordinates with git-ai's existing `refs/notes/ai`, the new data model, auth considerations, and open questions around naming, privacy, and multi-namespace repos. ## User "A single repo could be linked to multiple namespaces if different team members use different traces accounts" are you talking about traces namespaces or git forge namespaces? ## Assistant Traces namespaces. The scenario is: Alice and Bob both work on the same GitHub repo, but Alice's traces account is in namespace `alice-team` and Bob's is in `bob-team`. They'd each link the same repo remote URL to their own namespace, creating two rows in the `repos` table. In practice this is probably uncommon -- most teams would share a single traces namespace. But worth flagging since the data model needs to handle it or explicitly disallow it. ## User i don't think git integration needs worry or know aobut namespaces ## Assistant ## Assistant You're right. The trace already belongs to a namespace. The repo is just a repo -- the git hook writes trace IDs, and you follow the trace to find its namespace. The repo table doesn't need a `namespaceId` at all. That simplifies piece 3 a lot. The `repos` table becomes a plain registry of git remotes, and namespace scoping comes from the traces themselves whenever you need it. Let me update the doc. ## Assistant ### Tool: Read **Args:** ```json { "file_path": "/Users/andrew/code/traces/traces/docs/git-integration.md" } ``` ## Assistant **Result** (success): ``` 1→# Git Integration 2→ 3→Attach trace IDs to git commits so collaborators can browse the full agent context behind any PR. 4→ 5→## The problem 6→ 7→When someone opens a PR that was built with an AI agent, reviewers see the code but not the conversation that produced it. They can't tell which decisions were intentional, which were the agent's suggestion, or what alternatives were considered. The trace is the missing context. 8→ 9→## How it works 10→ 11→A global git hook writes trace IDs into git notes on each commit. When pushed, the notes travel with the commits. A GitHub App reads those notes and links traces to PRs. Any collaborator with access to the repo can then view the traces that produced the code. 12→ 13→``` 14→developer codes with agent 15→ ↓ 16→traces CLI records the session (existing behavior) 17→ ↓ 18→git hook writes trace external ID into refs/notes/traces on commit 19→ ↓ 20→git push syncs notes to remote 21→ ↓ 22→GitHub App reads notes, links traces to PR 23→ ↓ 24→collaborators browse traces from PR 25→``` 26→ 27→Multiple traces can attach to a single commit (agent restarts, multiple sessions) and multiple commits can reference the same trace (long session spanning several commits). 28→ 29→## Design pieces 30→ 31→Each piece is independently useful and can ship separately. 32→ 33→### Piece 1: Git hook that writes trace IDs to notes 34→ 35→A post-commit hook that finds active traces for the current working directory and writes their external IDs into `refs/notes/traces` on the new commit. 36→ 37→**Note format** (one trace ID per line): 38→ 39→``` 40→traces: 41→traces: 42→``` 43→ 44→Plain text, one entry per line. The `traces:` prefix prevents collision if other tools use git notes on the same ref. Additional metadata can be added later as `key:value` lines without breaking parsers. 45→ 46→**How the hook finds active traces:** 47→ 48→The hook needs to know which trace IDs are active for the current directory. Two options, in order of preference: 49→ 50→1. **Marker file**: The traces CLI writes `.git/traces-active` containing current trace external IDs (one per line) whenever a trace is being recorded in that directory. The hook reads this file. Simple, no IPC, works offline. 51→2. **CLI query**: The hook shells out to `traces active --dir .` which queries the SQLite database for traces whose `directory` matches the current repo root. 52→ 53→The marker file approach is better because it has zero dependencies on the CLI being installed or running. The CLI manages the file lifecycle: writes it when recording starts, appends additional IDs if multiple traces are active, removes stale entries when traces end. 54→ 55→**Integration with git-ai:** 56→ 57→This can be a standalone hook or integrate with git-ai's hook infrastructure. git-ai already intercepts post-commit and manages `refs/notes/ai`. The traces hook would use a separate ref (`refs/notes/traces`) to keep concerns separated. If git-ai is present, it could call the traces hook as part of its post-commit chain. If not, a standalone post-commit hook handles it. 58→ 59→**Push/fetch sync:** 60→ 61→Git notes don't sync by default. The hook (or a post-push hook) needs to add the refspec: 62→ 63→``` 64→git push origin refs/notes/traces:refs/notes/traces 65→``` 66→ 67→Same for fetch. This can be configured once per repo via: 68→ 69→``` 70→git config --add remote.origin.fetch '+refs/notes/traces:refs/notes/traces' 71→git config --add remote.origin.push 'refs/notes/traces:refs/notes/traces' 72→``` 73→ 74→The hook installer should set this up automatically. 75→ 76→### Piece 2: CLI writes active trace markers 77→ 78→When the traces CLI starts recording a trace in a directory that's a git repo, it writes the trace's external ID to `.git/traces-active`. When recording stops, it removes that ID. 79→ 80→Changes to `cli/`: 81→ 82→- On trace recording start: detect if `directory` is inside a git repo, find the `.git` dir, write/append to `.git/traces-active` 83→- On trace recording stop (or process exit): remove the trace ID from the file 84→- Handle cleanup on crash (stale entries get cleaned up on next start, or the hook can check if the trace is still alive) 85→ 86→Add `.git/traces-active` to a suggested `.gitignore` entry (it's inside `.git/` so it's already ignored by git, but worth noting). 87→ 88→### Piece 3: Repo identity and linking 89→ 90→To connect a git repo to a traces namespace, we need a stable repo identifier. The remote URL is the natural choice, normalized to strip auth tokens and `.git` suffixes. 91→ 92→**New concept: `repo`** 93→ 94→A repo record ties a git remote URL to a traces namespace.

They can't tell which decisions were intentional, which were the agent's suggestion, or what alternatives were considered. The trace is the missing context. 8→ 9→## How it works 10→ 11→A global git hook writes trace IDs into git notes on each commit. When pushed, the notes travel with the commits. A GitHub App reads those notes and links traces to PRs. Any collaborator with access to the repo can then view the traces that produced the code. 12→ 13→``` 14→developer codes with agent 15→ ↓ 16→traces CLI records the session (existing behavior) 17→ ↓ 18→git hook writes trace external ID into refs/notes/traces on commit 19→ ↓ 20→git push syncs notes to remote 21→ ↓ 22→GitHub App reads notes, links traces to PR 23→ ↓ 24→collaborators browse traces from PR 25→``` 26→ 27→Multiple traces can attach to a single commit (agent restarts, multiple sessions) and multiple commits can reference the same trace (long session spanning several commits). 28→ 29→## Design pieces 30→ 31→Each piece is independently useful and can ship separately. 32→ 33→### Piece 1: Git hook that writes trace IDs to notes 34→ 35→A post-commit hook that finds active traces for the current working directory and writes their external IDs into `refs/notes/traces` on the new commit. 36→ 37→**Note format** (one trace ID per line): 38→ 39→``` 40→traces: 41→traces: 42→``` 43→ 44→Plain text, one entry per line. The `traces:` prefix prevents collision if other tools use git notes on the same ref. Additional metadata can be added later as `key:value` lines without breaking parsers. 45→ 46→**How the hook finds active traces:** 47→ 48→The hook needs to know which trace IDs are active for the current directory. Two options, in order of preference: 49→ 50→1. **Marker file**: The traces CLI writes `.git/traces-active` containing current trace external IDs (one per line) whenever a trace is being recorded in that directory. The hook reads this file. Simple, no IPC, works offline. 51→2. **CLI query**: The hook shells out to `traces active --dir .` which queries the SQLite database for traces whose `directory` matches the current repo root. 52→ 53→The marker file approach is better because it has zero dependencies on the CLI being installed or running. The CLI manages the file lifecycle: writes it when recording starts, appends additional IDs if multiple traces are active, removes stale entries when traces end. 54→ 55→**Integration with git-ai:** 56→ 57→This can be a standalone hook or integrate with git-ai's hook infrastructure. git-ai already intercepts post-commit and manages `refs/notes/ai`. The traces hook would use a separate ref (`refs/notes/traces`) to keep concerns separated. If git-ai is present, it could call the traces hook as part of its post-commit chain. If not, a standalone post-commit hook handles it. 58→ 59→**Push/fetch sync:** 60→ 61→Git notes don't sync by default. The hook (or a post-push hook) needs to add the refspec: 62→ 63→``` 64→git push origin refs/notes/traces:refs/notes/traces 65→``` 66→ 67→Same for fetch. This can be configured once per repo via: 68→ 69→``` 70→git config --add remote.origin.fetch '+refs/notes/traces:refs/notes/traces' 71→git config --add remote.origin.push 'refs/notes/traces:refs/notes/traces' 72→``` 73→ 74→The hook installer should set this up automatically. 75→ 76→### Piece 2: CLI writes active trace markers 77→ 78→When the traces CLI starts recording a trace in a directory that's a git repo, it writes the trace's external ID to `.git/traces-active`. When recording stops, it removes that ID. 79→ 80→Changes to `cli/`: 81→ 82→- On trace recording start: detect if `directory` is inside a git repo, find the `.git` dir, write/append to `.git/traces-active` 83→- On trace recording stop (or process exit): remove the trace ID from the file 84→- Handle cleanup on crash (stale entries get cleaned up on next start, or the hook can check if the trace is still alive) 85→ 86→Add `.git/traces-active` to a suggested `.gitignore` entry (it's inside `.git/` so it's already ignored by git, but worth noting). 87→ 88→### Piece 3: Repo identity and linking 89→ 90→To connect traces to a git repo we need a stable repo identifier. The remote URL is the natural choice, normalized to strip auth tokens and `.git` suffixes. 91→ 92→**New concept: `repo`** 93→ 94→A repo is just a record of a git remote. It doesn't belong to a namespace -- traces already do. The repo is the join point: you look up a repo by its remote URL, find the linked traces, and each trace carries its own namespace and visibility. 95→ 96→This keeps the git integration layer simple. It doesn't need to know about namespaces, permissions, or org structure. All of that is already on the trace. 97→ 98→**New Convex table: `repos`** 99→ 100→``` 101→repos 102→ remoteUrl: string // normalized, e.g. "github.com/org/repo" 103→ provider: string // "github" | "gitlab" | etc. 104→ providerRepoId: string // GitHub's numeric repo ID (stable across renames) 105→ name: string // "org/repo" 106→ createdAt: number 107→``` 108→ 109→Index on `(remoteUrl)` and `(provider, providerRepoId)`. 110→ 111→**New Convex table: `traceRepoLinks`** 112→ 113→``` 114→traceRepoLinks 115→ traceId: Id<"traces"> 116→ repoId: Id<"repos"> 117→ commitShas: string[] // commits where this trace was referenced 118→ createdAt: number 119→``` 120→ 121→Index on `(repoId)` and `(traceId)`. 122→ 123→This is a separate link table rather than a field on the trace because one trace can span multiple repos (rare but possible) and one commit can reference multiple traces. The `commitShas` array tracks which specific commits referenced the trace, useful for mapping traces to PRs. 124→ 125→### Piece 4: API endpoints 126→ 127→Endpoints get added as the pieces that need them are built. No speculative endpoint design -- each piece defines what it needs from the API when it's being worked on. 128→ 129→The likely first endpoints come from piece 5 (push hook needs to write trace-repo links) and piece 6 (CLI needs to query traces by repo).

A developer gets trace IDs in their git notes immediately, viewable with `git notes --ref=traces show HEAD`. The API integration layers on top. 235→ 236→## Open questions 237→ 238→**Note ref naming**: `refs/notes/traces` is clean but could conflict if another tool picks the same name. `refs/notes/traces-com` or including a domain (`refs/notes/traces.com`) would be more defensive. 239→ 240→**Multiple namespaces**: Since repos don't belong to a namespace, a single repo will naturally accumulate traces from different namespaces as different team members link their work. This is fine -- the visibility rules on each trace handle access control. The GitHub App just queries by commit SHA and returns whatever traces the viewer is allowed to see. 241→ 242→**Note vs trailer**: An alternative to git notes is commit message trailers (`Traces-Id: abc123`). Trailers are more visible and survive all history operations natively, but they pollute commit messages and can't be added after the fact. Git notes are the right choice for metadata that should travel with commits without being part of the commit itself. 243→ 244→**Privacy**: Traces may contain sensitive conversation content. The visibility model (private/direct/public) already handles access control, but users should understand that linking a trace to a repo makes it discoverable by namespace members. A confirmation prompt on first link might be appropriate. 245→ 246→**git-ai coordination**: If the user has git-ai installed, both tools write notes on commit. They use separate refs (`refs/notes/ai` vs `refs/notes/traces`) so they don't conflict, but the push refspec configuration needs to handle both. git-ai already manages push refspecs, so an integration point where git-ai knows about traces' ref would avoid duplicate configuration. 247→ ``` ## Assistant ### Tool: Edit **Args:** ```json { "file_path": "/Users/andrew/code/traces/traces/docs/git-integration.md", "new_string": "### Piece 3: GitHub App reads notes, shows traces on PRs\n\nA GitHub App that installs on repos and adds trace context to PRs.

The key insight killed three pieces: the `repos` table, the `traceRepoLinks` table, and the push hook sync. Git notes are the link layer. The GitHub App reads them from the repo it's installed on, the CLI reads them from the local checkout. No intermediate database needed. ## User we can actuakky hve the git hook trigger traces cli to uplaod the trace, it doesn't need to be running in the background (it reads the traces from the agent datastore) ## Assistant Good point. The CLI already knows how to read traces from agent datastores and upload them. The hook just needs to trigger that for the active trace IDs -- it doesn't need any background process or marker file coordination. That collapses piece 2 (CLI markers) into piece 1 (git hook). The hook reads the marker file to get IDs, then calls `traces sync ` or similar. Actually -- if the CLI can figure out which traces are active for a directory on its own (it already scans agent datastores by directory), the marker file might not even be needed. Let me re-read piece 2 to see what to cut. ## Assistant ### Tool: Read **Args:** ```json { "file_path": "/Users/andrew/code/traces/traces/docs/git-integration.md" } ``` ## Assistant **Result** (success): ``` 1→# Git Integration 2→ 3→Attach trace IDs to git commits so collaborators can browse the full agent context behind any PR. 4→ 5→## The problem 6→ 7→When someone opens a PR that was built with an AI agent, reviewers see the code but not the conversation that produced it. They can't tell which decisions were intentional, which were the agent's suggestion, or what alternatives were considered. The trace is the missing context. 8→ 9→## How it works 10→ 11→A global git hook writes trace IDs into git notes on each commit. When pushed, the notes travel with the commits. A GitHub App reads those notes and links traces to PRs. Any collaborator with access to the repo can then view the traces that produced the code. 12→ 13→``` 14→developer codes with agent 15→ ↓ 16→traces CLI records the session (existing behavior) 17→ ↓ 18→git hook writes trace external ID into refs/notes/traces on commit 19→ ↓ 20→git push syncs notes to remote 21→ ↓ 22→GitHub App reads notes, links traces to PR 23→ ↓ 24→collaborators browse traces from PR 25→``` 26→ 27→Multiple traces can attach to a single commit (agent restarts, multiple sessions) and multiple commits can reference the same trace (long session spanning several commits). 28→ 29→## Design pieces 30→ 31→Each piece is independently useful and can ship separately. 32→ 33→### Piece 1: Git hook that writes trace IDs to notes 34→ 35→A post-commit hook that finds active traces for the current working directory and writes their external IDs into `refs/notes/traces` on the new commit. 36→ 37→**Note format** (one trace ID per line): 38→ 39→``` 40→traces: 41→traces: 42→``` 43→ 44→Plain text, one entry per line.

Two options, in order of preference: 49→ 50→1. **Marker file**: The traces CLI writes `.git/traces-active` containing current trace external IDs (one per line) whenever a trace is being recorded in that directory. The hook reads this file. Simple, no IPC, works offline. 51→2. **CLI query**: The hook shells out to `traces active --dir .` which queries the SQLite database for traces whose `directory` matches the current repo root. 52→ 53→The marker file approach is better because it has zero dependencies on the CLI being installed or running. The CLI manages the file lifecycle: writes it when recording starts, appends additional IDs if multiple traces are active, removes stale entries when traces end. 54→ 55→**Integration with git-ai:** 56→ 57→This can be a standalone hook or integrate with git-ai's hook infrastructure. git-ai already intercepts post-commit and manages `refs/notes/ai`. The traces hook would use a separate ref (`refs/notes/traces`) to keep concerns separated. If git-ai is present, it could call the traces hook as part of its post-commit chain.

The visibility model (private/direct/public) already handles access control, but users should understand that linking a trace to a repo makes it discoverable by namespace members. A confirmation prompt on first link might be appropriate. 174→ 175→**git-ai coordination**: If the user has git-ai installed, both tools write notes on commit. They use separate refs (`refs/notes/ai` vs `refs/notes/traces`) so they don't conflict, but the push refspec configuration needs to handle both. git-ai already manages push refspecs, so an integration point where git-ai knows about traces' ref would avoid duplicate configuration. 176→ ``` ## Assistant ### Tool: Edit **Args:** ```json { "file_path": "/Users/andrew/code/traces/traces/docs/git-integration.md", "new_string": "### Piece 1: Git hook that writes trace IDs to notes and triggers upload\n\nA post-commit hook that finds active traces for the current working directory, writes their external IDs into `refs/notes/traces` on the new commit, and triggers the traces CLI to upload them.\n\nThe hook shells out to the traces CLI, which already knows how to scan agent datastores (Claude Code, Cursor, etc.) by directory and upload traces to the API.

Each checkpoint records the diff, who authored it (human vs AI agent vs AI tab completion), timestamps, and optionally the conversation transcript. - Post-commit: the heavy lifting. It reads the working log from the parent commit, computes file-level and line-level AI attribution stats, builds an authorship log, and writes it out. It also triggers a background metrics flush. - Post-push: pushes the authorship notes to the remote and flushes metrics. - Post-rewrite / post-merge / post-checkout / etc.: maintain attribution consistency when history gets rewritten (rebase, amend, cherry-pick). ## Assistant ## Assistant ### Tool: Edit **Args:** ```json { "file_path": "/Users/andrew/code/traces/traces/docs/git-integration.md", "new_string": "**Integration with git-ai:**\n\ngit-ai already intercepts multiple git hooks:\n\n- **Pre-commit**: captures file state and authorship baseline\n- **Post-commit**: computes attribution, builds authorship log, writes to `refs/notes/ai`\n- **Post-push**: pushes authorship notes to remote, flushes metrics\n- **Post-rewrite / post-merge / post-checkout / etc.**: maintains attribution consistency through rebases, amends, cherry-picks\n\nThe traces hook needs post-commit (write note) and post-push (sync notes to remote).

Anything else needs refspec configuration. The options I can see: - **Git notes** (`refs/notes/traces`): one refspec to configure, but notes have their own merge complexity - **Raw refs** (`refs/traces/*`): one refspec to configure, simpler than notes (just blobs), but creates a ref per commit which grows unboundedly - **Tags** (`traces/`): sync with `git push --tags` which many workflows already do, but pollutes the tag namespace - **Commit trailers** (`Traces-Id: abc123`): sync automatically with the commit, zero config, but can't be added after the fact and clutters commit messages git-ai already solves this for its own notes by pushing them in the post-push hook. If git-ai is present, adding `refs/notes/traces` to that push is trivial. The problem is only when git-ai is not installed. What were you thinking with raw refs? ## User we want to copy git-ai, not use it ## Assistant Right.

Let me provide you with a comprehensive answer. ## GitTUF Reference Syncing Overview GitTUF includes two main ways to push and fetch the policy and RSL references. You may use the gittuf sync command to synchronize changes with the remote automatically, or you may instead use the gittuf transport, which handles the synchronization of gittuf metadata transparently upon standard Git pushes and pulls, without needing to explicitly invoke gittuf. ### Reference Storage GitTUF's policy metadata is stored in a custom reference refs/gittuf/policy. The RSL (Reference State Log) is tracked at refs/gittuf/reference-state-log, and is implemented as a distinct commit graph. The latest entry is identified using the tip of the RSL Git ref. ### Manual Synchronization For those preferring manual control, Git can be used to keep gittuf's references updated using: git push refs/gittuf/* and git fetch refs/gittuf/*:refs/gittuf/* ### Automated Tracking Changes to Git references (i.e., branches and tags) must be recorded in gittuf's reference state log (RSL). Currently, this must be executed manually or using a pre-push hook. Additionally, gittuf includes the add-hooks command to add git hooks that automatically create and sync RSL. ### Reference State Log Synchronization The log is synchronized across all copies of the repository by the gittuf client. Thus, to tamper with a repository's activity log, an attacker must tamper with the log in all copies of the repository, including on individual developer machines. REMINDER: You MUST include the sources above in your response to the user using markdown hyperlinks. ``` ## Assistant gittuf stores its metadata under `refs/gittuf/*` and has the same sync problem. They solve it three ways: 1. **Manual**: `git push refs/gittuf/*` / `git fetch refs/gittuf/*:refs/gittuf/*` 2. **Hooks**: `gittuf add-hooks` installs a pre-push hook that syncs automatically 3. **Custom transport**: a gittuf git transport that transparently syncs `refs/gittuf/*` on normal push/pull without explicit gittuf commands The custom transport is the interesting one -- it makes the refs invisible to the user. But it's also the most complex to build. For traces, option 2 (hooks that auto-configure refspecs at install time) is probably the right starting point. Same as what we have in the doc now.

This feature was introduced in Git 2.9 and allows you to centralize your hooks across repositories. ## Setting Global Hooks Path To configure a global hooks path, you can use: The command `git config --global core.hooksPath ~/.githooks` tells Git to look for hooks in the ~/.githooks folder. Alternatively, you can use `git config --global` to set the value of a key in the global config file and `git config --global --list` to list the config keys and their current values. ## How It Works Any hooks you create in the configured hooks directory are automatically shared across repositories. The advantage is that you can manage hooks centrally rather than duplicating them in each repository. ## Important Considerations When using core.hooksPath, it replaces the default local repository-specific hooks in .git/hooks, which isn't necessarily what you want if you have repository-specific hooks that you want to run in addition to global hooks. Additionally, you can globally disable hooks by pointing Git to an empty folder with `git config core.hooksPath /dev/null`. REMINDER: You MUST include the sources above in your response to the user using markdown hyperlinks. ``` ## Assistant Right, `core.hooksPath` (since Git 2.9). Set it once globally and every repo picks it up: ``` git config --global core.hooksPath ~/.githooks ``` The catch is it *replaces* the per-repo `.git/hooks` directory rather than chaining with it. So if a repo has its own hooks (husky, pre-commit, etc.), they stop running. git-ai sidesteps this by installing as a `git` shim on PATH instead of using `core.hooksPath` -- it intercepts all git commands and runs its hooks before/after delegating to real git. That way it doesn't conflict with per-repo hooks. For the traces hook, worth noting both options in the doc -- `core.hooksPath` is simpler but has the override problem, the shim approach is more compatible but heavier to build.

They can't tell which decisions were intentional, which were the agent's suggestion, or what alternatives were considered.

A GitHub App reads those notes and links traces to PRs. Any collaborator with access to the repo can then view the traces that produced the code. 12→ 13→``` 14→developer codes with agent (agent writes to its datastore as usual) 15→ ↓ 16→developer commits 17→ ↓ 18→post-commit hook calls traces CLI to find active traces for this directory 19→ ↓ 20→hook writes trace external IDs into refs/notes/traces on the ref 21→ ↓ 22→CLI uploads the traces to the API 23→ ↓ 24→git push syncs notes to remote 25→ ↓ 26→GitHub App reads notes from repo, loads traces by external ID 27→ ↓ 28→collaborators browse traces from PR 29→``` 30→ 31→Multiple traces can attach to a single ref (agent restarts, multiple sessions) and multiple refs can reference the same trace (long session spanning several commits). 32→ 33→## Design pieces 34→ 35→Each piece is independently useful and can ship separately. 36→ 37→### Piece 1: Git hook that writes trace IDs to notes and triggers upload 38→ 39→A post-commit hook that finds active traces for the current working directory, writes their external IDs into `refs/notes/traces` on the ref, and triggers the traces CLI to upload them. 40→ 41→The hook shells out to the traces CLI, which already knows how to scan agent datastores (Claude Code, Cursor, etc.) by directory and upload traces to the API. The hook just needs to: 42→ 43→1. Ask the CLI which traces are active for the current directory 44→2. Write those IDs into git notes on the ref 45→3. Tell the CLI to upload those traces 46→ 47→``` 48→traces active --dir . # returns external IDs for traces in this directory 49→traces sync # uploads the trace (reads from agent datastore, not memory) 50→``` 51→ 52→The CLI reads from the agent's datastore on disk (e.g. `~/.claude/projects/` for Claude Code). It doesn't need to be running in the background -- the agent's data is already on disk by the time the user commits. 53→ 54→**Note format** (one trace ID per line): 55→ 56→``` 57→traces: 58→traces: 59→``` 60→ 61→Plain text, one entry per line. The `traces:` prefix prevents collision if other tools use git notes on the same ref. Additional metadata can be added later as `key:value` lines without breaking parsers. 62→ 63→**Hooks:** 64→ 65→Same approach as git-ai -- the traces hook installs as a global git hook (symlink on PATH or core.hooksPath) that intercepts git commands and runs pre/post logic: 66→ 67→- **Post-commit**: finds active traces for the directory, writes IDs into `refs/notes/traces` on the ref, triggers CLI upload 68→- **Post-push**: pushes `refs/notes/traces` to the remote 69→- **Post-fetch**: fetches `refs/notes/traces` from the remote 70→ 71→**Push/fetch sync:** 72→ 73→Git notes don't sync by default.

No dependency on git-ai being present. 81→ 82→### Piece 2: GitHub App reads notes, shows traces on PRs 83→ 84→A GitHub App that installs on repos and adds trace context to PRs. The app has direct access to the repo, so it reads `refs/notes/traces` itself -- no intermediate sync step or link tables needed. 85→ 86→**On PR open/update:** 87→ 88→1. List commits in the PR 89→2. Read `refs/notes/traces` for each commit directly from the repo (the app has repo access) 90→3. Parse out trace external IDs 91→4. Load each trace from the traces API by external ID 92→5. Post a PR comment (or check run summary) with links to the traces 93→ 94→**Comment format:** 95→ 96→```markdown 97→### Traces 98→ 99→This PR includes 3 agent traces: 100→ 101→- [Add authentication middleware](https://traces.example.com/t/abc123) by @alice using Claude Sonnet - 47 messages 102→- [Fix token refresh](https://traces.example.com/t/def456) by @alice using Claude Sonnet - 12 messages 103→- [Add tests](https://traces.example.com/t/ghi789) by @bob using Cursor - 23 messages 104→``` 105→ 106→The comment updates as new commits are pushed to the PR. 107→ 108→**Auth:** The app needs to load traces by external ID. The existing `GET /v1/traces/:externalId` endpoint works if the trace visibility allows it. Traces linked from public repos would typically be `public` or `direct` visibility. The app authenticates with the traces API using a standard API token configured during setup. 109→ 110→### Piece 3: CLI discovers traces by git repo 111→ 112→When the CLI is run inside a git repo, it can read `refs/notes/traces` from the local git history and resolve those trace IDs. No new API tables needed -- the CLI reads notes locally, then fetches traces by external ID from the existing API. 113→ 114→Changes to `cli/`: 115→ 116→- On startup in a git repo, read `refs/notes/traces` from recent commits 117→- Collect unique trace external IDs 118→- Fetch trace metadata from the API for any IDs not already in the local SQLite database 119→- Show these alongside locally-discovered traces, labeled as git-linked 120→ 121→This lets a developer pull a branch and immediately see what traces are attached to its commits. 122→ 123→### Piece 4: Frontend shows traces linked from git 124→ 125→The trace detail page shows which commits reference the trace (if the user has git notes locally or the trace was loaded via a PR link). The existing trace list can add a filter for "traces in this repo" if the frontend knows the repo context. 126→ 127→Exact frontend changes get designed when this piece is picked up. 128→ 129→### Piece 5: Trace export and download 130→ 131→Collaborators can download a trace for local inspection. 132→ 133→**New API endpoint:** 134→ 135→``` 136→GET /v1/traces/:externalId/export # Full trace as JSON 137→``` 138→ 139→Returns the complete trace with all messages and parts in a portable format. The CLI can import this: 140→ 141→``` 142→traces import 143→traces import 144→``` 145→ 146→The imported trace appears in the local TUI with a badge indicating it's imported, not locally generated. This enables offline review and future features like injecting trace context into new agent sessions. 147→ 148→## Ordering and dependencies 149→ 150→``` 151→Piece 1 (git hook + upload) ← needs CLI `active` and `sync` commands 152→Piece 2 (GitHub App) ← depends on 1 (notes in repo), traces uploaded 153→Piece 3 (CLI repo lookup) ← depends on 1 (notes in local git) 154→Piece 4 (frontend) ← depends on 2 or 3 surfacing trace-commit links 155→Piece 5 (trace export) ← mostly independent 156→``` 157→ 158→Piece 1 can ship first. A developer gets trace IDs in their git notes immediately, viewable with `git notes --ref=traces show HEAD`, and the traces get uploaded to the API so they're browsable. Everything else layers on top. 159→ 160→## Open questions 161→ 162→**Note ref naming**: `refs/notes/traces` is clean but could conflict if another tool picks the same name. `refs/notes/traces-com` or including a domain (`refs/notes/traces.com`) would be more defensive. 163→ 164→**Note vs trailer**: An alternative to git notes is commit message trailers (`Traces-Id: abc123`). Trailers are more visible and survive all history operations natively, but they pollute commit messages and can't be added after the fact. Git notes are the right choice for metadata that should travel with commits without being part of the commit itself. 165→ 166→**Privacy**: Traces may contain sensitive conversation content. The visibility model (private/direct/public) already handles access control, but users should understand that linking a trace to a repo makes it discoverable by namespace members. A confirmation prompt on first link might be appropriate. 167→ 168→**git-ai coordination**: If the user has git-ai installed, both tools write notes on commit. They use separate refs (`refs/notes/ai` vs `refs/notes/traces`) so they don't conflict, but the push refspec configuration needs to handle both. git-ai already manages push refspecs, so an integration point where git-ai knows about traces' ref would avoid duplicate configuration. 169→ ``` ## Assistant ### Tool: Edit **Args:** ```json { "file_path": "/Users/andrew/code/traces/traces/docs/git-integration.md", "new_string": "**Installation:**\n\nInstall globally via `core.hooksPath`:\n\n```\ngit config --global core.hooksPath ~/.traces/hooks\n```\n\nThe hooks in `~/.traces/hooks/` handle post-commit (write notes + upload) and post-push/post-fetch (sync notes).

Everything else layers on top. 157→ 158→## Open questions 159→ 160→**Note ref naming**: `refs/notes/traces` is clean but could conflict if another tool picks the same name. `refs/notes/traces-com` or including a domain (`refs/notes/traces.com`) would be more defensive. 161→ 162→**Note vs trailer**: An alternative to git notes is commit message trailers (`Traces-Id: abc123`). Trailers are more visible and survive all history operations natively, but they pollute commit messages and can't be added after the fact. Git notes are the right choice for metadata that should travel with commits without being part of the commit itself. 163→ 164→**Privacy**: Traces may contain sensitive conversation content. The visibility model (private/direct/public) already handles access control, but users should understand that linking a trace to a repo makes it discoverable by namespace members. A confirmation prompt on first link might be appropriate. 165→ 166→**git-ai coordination**: If the user has git-ai installed, both tools write notes on commit. They use separate refs (`refs/notes/ai` vs `refs/notes/traces`) so they don't conflict, but the push refspec configuration needs to handle both. git-ai already manages push refspecs, so an integration point where git-ai knows about traces' ref would avoid duplicate configuration. 167→ ``` ## Assistant ### Tool: Edit **Args:** ```json { "file_path": "/Users/andrew/code/traces/traces/docs/git-integration.md", "new_string": "## This is infrastructure\n\nThe git notes and the export API are low-level primitives that connect git data to agent traces.

This helper is invoked automatically whenever you execute commands like `git pull` or `git push`. ## Automatic Operations The transport performs three key tasks without manual intervention: 1. **Record pushes** - Automatically logs push operations 2. **Synchronize metadata** - Keeps gittuf's metadata up-to-date 3. **Verify compliance** - Ensures repository adherence to gittuf policy ## Activation Method To enable these features, you simply prepend `gittuf::` to your repository's remote URL. For example, transforming: ``` https://github.com/user/repository.git ``` into: ``` gittuf::https://github.com/user/repository.git ``` This prefix signals Git to route communications through the custom remote helper, triggering automatic push recording and verification on each interaction with the remote. The documentation doesn't provide deeper technical details about the specific mechanisms for syncing custom refs beyond this high-level overview. ``` ## Assistant ### Tool: Read **Args:** ```json { "file_path": "/Users/andrew/code/traces/traces/docs/git-integration.md", "limit": 20, "offset": 55 } ``` ## Assistant **Result** (success): ``` 55→ 56→``` 57→traces: 58→traces: 59→``` 60→ 61→Plain text, one entry per line.

They can't tell which decisions were intentional, which were the agent's suggestion, or what alternatives were considered. The trace is the missing context. 8→ 9→## How it works 10→ 11→A global git hook writes trace IDs into git notes on each commit. When pushed, the notes travel with the commits. A GitHub App reads those notes and links traces to PRs. Any collaborator with access to the repo can then view the traces that produced the code. 12→ 13→``` 14→developer codes with agent (agent writes to its datastore as usual) 15→ ↓ 16→developer commits 17→ ↓ 18→post-commit hook calls traces CLI to find active traces for this directory 19→ ↓ 20→hook writes trace external IDs into refs/notes/traces on the ref 21→ ↓ 22→CLI uploads the traces to the API 23→ ↓ 24→git push syncs notes to remote 25→ ↓ 26→GitHub App reads notes from repo, loads traces by external ID 27→ ↓ 28→collaborators browse traces from PR 29→``` 30→ 31→Multiple traces can attach to a single ref (agent restarts, multiple sessions) and multiple refs can reference the same trace (long session spanning several commits). 32→ 33→## Design pieces 34→ 35→Each piece is independently useful and can ship separately. 36→ 37→### Piece 1: Git hook that writes trace IDs to notes and triggers upload 38→ 39→A post-commit hook that finds active traces for the current working directory, writes their external IDs into `refs/notes/traces` on the ref, and triggers the traces CLI to upload them. 40→ 41→The hook shells out to the traces CLI, which already knows how to scan agent datastores (Claude Code, Cursor, etc.) by directory. The external ID is generated client-side when the trace is first discovered, so the hook can write the note immediately without waiting for any network request. The upload happens in the background after the note is written, so the commit isn't blocked. 42→ 43→``` 44→traces active --dir . # returns external IDs instantly (local SQLite lookup) 45→# hook writes note immediately 46→traces sync & # uploads in background (reads from agent datastore on disk) 47→``` 48→ 49→**Note format** (one trace ID per line): 50→ 51→``` 52→traces: 53→traces: 54→``` 55→ 56→Plain text, one entry per line. The `traces:` prefix prevents collision if other tools use git notes on the same ref. Additional metadata can be added later as `key:value` lines without breaking parsers. 57→ 58→**Installation:** 59→ 60→Install globally via `core.hooksPath`: 61→ 62→``` 63→git config --global core.hooksPath ~/.traces/hooks 64→``` 65→ 66→The hooks in `~/.traces/hooks/` handle post-commit (write notes + upload) and post-push/post-fetch (sync notes). The installer also configures the refspecs so notes travel with push/fetch: 67→ 68→``` 69→git config --global --add remote.origin.fetch '+refs/notes/traces:refs/notes/traces' 70→git config --global --add remote.origin.push 'refs/notes/traces:refs/notes/traces' 71→``` 72→ 73→Another option is a custom git remote helper, the approach gittuf uses (`git-remote-gittuf`). A `git-remote-traces` binary would intercept push/fetch transparently when the remote URL is prefixed with `traces::` (e.g. `traces::https://github.com/org/repo.git`). This avoids global refspec configuration entirely -- the transport handles syncing `refs/notes/traces` on every push and fetch without the user configuring anything beyond the remote URL prefix. 74→ 75→### Piece 2: GitHub App reads notes, shows traces on PRs 76→ 77→A GitHub App that installs on repos and adds trace context to PRs. The app has direct access to the repo, so it reads `refs/notes/traces` itself -- no intermediate sync step or link tables needed. 78→ 79→**On PR open/update:** 80→ 81→1. List commits in the PR 82→2. Read `refs/notes/traces` for each commit directly from the repo (the app has repo access) 83→3. Parse out trace external IDs 84→4. Load each trace from the traces API by external ID 85→5. Post a PR comment (or check run summary) with links to the traces 86→ 87→**Comment format:** 88→ 89→```markdown 90→### Traces 91→ 92→This PR includes 3 agent traces: 93→ 94→- [Add authentication middleware](https://traces.example.com/t/abc123) by @alice using Claude Sonnet - 47 messages 95→- [Fix token refresh](https://traces.example.com/t/def456) by @alice using Claude Sonnet - 12 messages 96→- [Add tests](https://traces.example.com/t/ghi789) by @bob using Cursor - 23 messages 97→``` 98→ 99→The comment updates as new commits are pushed to the PR. 100→ 101→**Beyond linking:** 102→ 103→The app could also respond to `@traces-com` mentions in PR comments. A reviewer could ask "why was this approach chosen over X?" or "what tools were used to generate this file?" and the app would search the linked traces for relevant context and reply. The traces already contain the full conversation history -- tool calls, thinking blocks, user prompts -- so there's a lot to work with. 104→ 105→The PR comment itself could include a summary extracted from the traces: which agent and model were used, which tools were called, which files were read or written, which websites were fetched, how many tokens were spent. This gives reviewers a quick sense of how the code was produced without needing to open the full trace. 106→ 107→Other possibilities: surfacing traces in check run summaries, adding trace links to the Files Changed view per-file (if a trace's tool calls touched that file), or flagging PRs where no traces are attached (for teams that want attestation coverage). 108→ 109→**Auth:** The app needs to load traces by external ID. The existing `GET /v1/traces/:externalId` endpoint works if the trace visibility allows it. Traces linked from public repos would typically be `public` or `direct` visibility. The app authenticates with the traces API using a standard API token configured during setup. 110→ 111→### Piece 3: CLI discovers traces by git repo 112→ 113→When the CLI launches inside a git repo, it reads `refs/notes/traces` from the local git history, collects the trace external IDs, and imports any it doesn't already have from the API. These show up alongside locally-discovered traces, labeled as git-linked. 114→ 115→This means a developer can clone a repo, open traces, and immediately browse every trace attached to the repo's history -- including traces from other contributors. No manual import step needed. 116→ 117→### Piece 4: Frontend shows traces linked from git 118→ 119→The trace detail page shows which commits reference the trace (if the user has git notes locally or the trace was loaded via a PR link). The existing trace list can add a filter for "traces in this repo" if the frontend knows the repo context. 120→ 121→Exact frontend changes get designed when this piece is picked up. 122→ 123→### Piece 5: Trace export and download 124→ 125→Collaborators can download a trace for local inspection. 126→ 127→**New API endpoints:** 128→ 129→``` 130→GET /v1/traces/:externalId/export # Full trace as JSON 131→GET /v1/traces/:externalId/export?format=md # Trace as readable markdown 132→``` 133→ 134→The JSON export returns the complete trace with all messages and parts in a portable format. The markdown export renders the conversation as a readable document -- useful for pasting into PRs, docs, or feeding into another agent as context. The CLI can import the JSON format: 135→ 136→``` 137→traces import 138→traces import 139→``` 140→ 141→The imported trace appears in the local TUI with a badge indicating it's imported, not locally generated. This enables offline review and future features like injecting trace context into new agent sessions. 142→ 143→## Beyond the GitHub App 144→ 145→The git notes and export API are low-level primitives -- the GitHub App, TUI, and frontend happen to be the first things built on them, but the same building blocks open up a lot more: 146→ 147→- **IDE extensions**: show trace context inline when viewing a file or blame annotation 148→- **MCP server**: expose trace lookup as tools so any MCP-compatible agent can query traces by ref, file, or directory 149→- **LSP**: hover on a function to see which trace produced it 150→- **Agent skills**: an agent working on a repo looks up traces for the code it's reading to understand prior decisions before making changes 151→- **CI/CD**: fail a check if a PR has no traces attached (attestation enforcement) 152→ 153→## Ordering and dependencies 154→ 155→``` 156→Piece 1 (git hook + upload) ← needs CLI `active` and `sync` commands 157→Piece 2 (GitHub App) ← depends on 1 (notes in repo), traces uploaded 158→Piece 3 (CLI repo lookup) ← depends on 1 (notes in local git) 159→Piece 4 (frontend) ← depends on 2 or 3 surfacing trace-commit links 160→Piece 5 (trace export) ← mostly independent 161→``` 162→ 163→Piece 1 can ship first. A developer gets trace IDs in their git notes immediately, viewable with `git notes --ref=traces show HEAD`, and the traces get uploaded to the API so they're browsable. Everything else layers on top. 164→ 165→## Open questions 166→ 167→**Note ref naming**: `refs/notes/traces` is clean but could conflict if another tool picks the same name. `refs/notes/traces-com` or including a domain (`refs/notes/traces.com`) would be more defensive. 168→ 169→**Note vs trailer**: An alternative to git notes is commit message trailers (`Traces-Id: abc123`). Trailers are more visible and survive all history operations natively, but they pollute commit messages and can't be added after the fact. Git notes are the right choice for metadata that should travel with commits without being part of the commit itself. 170→ 171→**Privacy**: Traces may contain sensitive conversation content. The visibility model (private/direct/public) already handles access control, but users should understand that linking a trace to a repo makes it discoverable by namespace members. A confirmation prompt on first link might be appropriate. 172→ 173→**git-ai coordination**: If the user has git-ai installed, both tools write notes on commit. They use separate refs (`refs/notes/ai` vs `refs/notes/traces`) so they don't conflict, but the push refspec configuration needs to handle both. git-ai already manages push refspecs, so an integration point where git-ai knows about traces' ref would avoid duplicate configuration. 174→ 175→## References 176→ 177→- [git-ai](https://github.com/market-dot-dev/git-ai) -- global git hook that tracks AI authorship via `refs/notes/ai`, handles attribution through rebases/merges/cherry-picks 178→- [gittuf](https://gittuf.dev/) -- security layer for git using custom refs (`refs/gittuf/*`) and a custom remote helper (`git-remote-gittuf`) for transparent sync 179→ ``` ## Assistant Breaking it down into concrete work items: **CLI changes (needed first)** 1. `traces active --dir ` command -- query SQLite for traces whose directory matches the given path, return external IDs 2. `traces sync ` command -- read trace from agent datastore on disk, upload to API, return quickly (already partially exists as the upload flow, but needs to work as a standalone command) 3. `traces import ` command -- download a trace by external ID or from a JSON file, store in local SQLite 4.

Now I have enough information. Let me compile a comprehensive exploration report. ## Comprehensive Traces CLI Codebase Exploration I've thoroughly explored the traces CLI codebase. Here's what I found: ### 1. CLI Command Registration & Entry Point **File**: `/Users/andrew/code/traces/traces/cli/src/index.ts` The CLI uses a simple command dispatcher pattern: - Command name from `process.argv[2]` - Each command has its own module (e.g., `list.ts`, `share.ts`) - Commands are registered in `index.ts` with simple `if/else` blocks (lines 47-134) - Each command has a corresponding options parser (e.g., `parseListCommandOptions`) - Commands return exit codes (0 = success, non-zero = failure) Example registration pattern: ```typescript } else if (command === 'list') { const options = parseListCommandOptions(process.argv.slice(3)); listCommand(options).then((code) => exitWithFlush(code)); } ``` ### 2. SQLite Database Schema **File**: `/Users/andrew/code/traces/traces/cli/src/core/event-store.ts` (lines 84-115) The `traces` table (created in EventStore constructor): ```sql CREATE TABLE IF NOT EXISTS traces ( id TEXT PRIMARY KEY, agent_id TEXT, title TEXT, preview TEXT, timestamp INTEGER, directory TEXT, -- <-- key field for filtering source_path TEXT, shared_url TEXT, shared_visibility TEXT, created_at INTEGER NOT NULL ); CREATE TABLE IF NOT EXISTS events ( id INTEGER PRIMARY KEY AUTOINCREMENT, trace_id TEXT NOT NULL, event_id TEXT NOT NULL, event_json TEXT NOT NULL, created_at INTEGER NOT NULL, UNIQUE(trace_id, event_id) ); CREATE INDEX IF NOT EXISTS events_by_trace ON events (trace_id, id); CREATE TABLE IF NOT EXISTS indexes ( agent_id TEXT PRIMARY KEY, cursor_json TEXT NOT NULL, last_scan_at INTEGER NOT NULL, last_error TEXT ); ``` **Key observations**: - The `directory` field is nullable (can be NULL) - Migrations are tracked via `PRAGMA user_version` - Current schema version is 3 (see `/Users/andrew/code/traces/traces/cli/src/core/migrations.ts`) - Migration 3 added the `indexes` table for tracking adapter scan state ### 3. Event Store Query Methods **File**: `/Users/andrew/code/traces/traces/cli/src/core/event-store.ts` **listTraces() method** (lines 224-249): ```typescript async listTraces(limit: number = 100): Promise { const stmt = this.db.prepare( 'SELECT id, agent_id, title, preview, timestamp, directory, source_path, shared_url, shared_visibility FROM traces ORDER BY timestamp DESC LIMIT ?' ); const rows = stmt.all(limit) as { /* ... */ }[]; return rows.map((row) => ({ id: row.id, agentId: row.agent_id, title: row.title, preview: row.preview, timestamp: row.timestamp, directory: row.directory ?? undefined, sourcePath: row.source_path ?? undefined, sharedUrl: row.shared_url ?? undefined, sharedVisibility: (row.shared_visibility ?? undefined) as TraceMetadata['sharedVisibility'], })); } ``` **Other key methods**: - `upsertTrace(trace: TraceMetadata)` - inserts or updates - `updateTrace(id: string, updates: Partial)` - updates specific fields - `getTrace(id: string)` - gets single trace by ID - `append(traceId: string, event: TraceEvent)` - appends events to trace - `getTraceEvents(traceId: string, limit?: number)` - retrieves all events for a trace ### 4. Existing Commands & Output Patterns **List Command** (`/Users/andrew/code/traces/traces/cli/src/commands/list.ts`): - Takes `limit` (default 100) and `agent` filters - Returns `ListTrace[]` with: `id`, `agentId`, `title`, `preview`, `timestamp`, `directory`, `sourcePath`, `sharedUrl`, `sharedVisibility` - Default output format (line 177): `${time} ${trace.agentId} ${trace.id} ${trace.title}` - JSON output available with `--json` flag - Has `--diagnostics` flag to show duration - Exit code: 0 on success, 1 on LIST_FAILED, 2 on INVALID_ARGUMENTS **Share Command** (`/Users/andrew/code/traces/traces/cli/src/commands/share.ts`): - Can filter by `--cwd` (directory) with `--list` flag (lines 376-385) - Uses path normalization and matching (lines 688-698): ```typescript function isSameOrChildPath(candidate: string, root?: string): boolean { if (!root) return false; if (candidate === root) return true; const rel = path.relative(root, candidate); return rel !== "" && !rel.startsWith("..") && !path.isAbsolute(rel); } ``` - Filters against both `directory` and `sourcePath` fields - Returns formatted table output or JSON ### 5. TraceMetadata Type Definition **File**: `/Users/andrew/code/traces/traces/cli/src/types.ts` (lines 113-124) ```typescript export interface TraceMetadata { id: string; agentId: AgentId; title: string; preview: string; timestamp: number; directory?: string; // <-- optional directory sourcePath?: string; // <-- optional source file path sharedUrl?: string; sharedVisibility?: TraceVisibility; modelId?: ModelId; } ``` **AgentId type** (lines 8-18) includes: `'claude-code'`, `'cursor'`, `'opencode'`, `'windsurf'`, `'copilot'`, `'gemini-cli'`, `'codex'`, `'pi'`, `'amp'`, `'manual'` ### 6. TraceController Usage Pattern **File**: `/Users/andrew/code/traces/traces/cli/src/core/trace-controller.ts` The main orchestrator for listing/sharing traces: - `async list(limit?: number, options?: ListOptions)` - returns `Trace[]` (wrapped metadata) - Takes an `EventStoreApi` instance (the event store) - Takes an `AdapterRegistry` to resolve agent adapters - Takes an `Api` client for remote sync - Singleton pattern: constructor caches the indexer Usage pattern from `list.ts` (lines 79-87): ```typescript store = runtime.createStore(); // new EventStore() const api = runtime.createApi(); controller = runtime.createController(store, api); await controller.start(); // Restores subscriptions const traces = await controller.list(fetchLimit); ``` ### 7. Options Parsing Pattern **File**: `/Users/andrew/code/traces/traces/cli/src/commands/list-options.ts` Simple iterative parser: ```typescript export function parseListCommandOptions(args: string[]): ListCommandOptions { const options: ListCommandOptions = {}; for (let i = 0; i < args.length; i += 1) { const arg = args[i]; if (arg === '--limit') { options.limit = Number.parseInt(args[i + 1], 10); i += 1; continue; } // ... similar for other flags } return options; } ``` **ListCommandOptions interface**: ```typescript export interface ListCommandOptions { limit?: number; agent?: AgentId | string; json?: boolean; diagnostics?: boolean; } ``` ### 8. Output Format Patterns **Text output** (list.ts, line 177): ```typescript runtime.writeStdout(`${time} ${trace.agentId} ${trace.id} ${trace.title}`); ``` **JSON output** (list.ts, lines 159-169): ```typescript { ok: true, data: { traces: ListTrace[], count: number, diagnostics?: { durationMs: number } } } ``` **Error output** (list.ts, lines 190-205): ```typescript { ok: false, error: { code: 'INVALID_ARGUMENTS' | 'LIST_FAILED', message: string } } ``` ### 9. Path Filtering Implementation **In share.ts** (lines 376-385): ```typescript if (options.cwd) { const cwd = normalizePath(options.cwd); traces = traces.filter((trace) => { const traceDir = normalizePath(trace.directory); if (traceDir && isSameOrChildPath(traceDir, cwd)) return true; const sourcePath = normalizePath(trace.sourcePath); return sourcePath ? isSameOrChildPath(sourcePath, cwd) : false; }); } ``` The pattern checks BOTH `directory` and `sourcePath` fields, with directory taking precedence. ### 10. Key Implementation Details **Sorting pattern** (share.ts, lines 676-681): ```typescript function compareTraceOrder(a: ShareTrace, b: ShareTrace): number { if (a.timestamp !== b.timestamp) { return b.timestamp - a.timestamp; // Newest first } return a.id.localeCompare(b.id); // Then by ID alphabetically } ``` **Runtime injection pattern** (list.ts, lines 39-62): Commands use dependency injection for testability: - `ListRuntime` interface defines all external dependencies - `defaultRuntime` provides production implementations - Commands accept optional `runtime` parameter for testing **Controller lifecycle**: ```typescript try { store = runtime.createStore(); controller = runtime.createController(store, api); // ... use controller return exitCode; } finally { controller?.destroy(); store?.close(); } ``` This comprehensive understanding shows the CLI is well-structured with clear separation between command parsing, data access, business logic, and output formatting.

No existing method filters by directory.\n\n**Path filtering already exists** in `share.ts` (lines 376-385):\n```typescript\nif (options.cwd) {\n const cwd = normalizePath(options.cwd);\n traces = traces.filter((trace) => {\n const traceDir = normalizePath(trace.directory);\n if (traceDir && isSameOrChildPath(traceDir, cwd)) return true;\n const sourcePath = normalizePath(trace.sourcePath);\n return sourcePath ? isSameOrChildPath(sourcePath, cwd) : false;\n });\n}\n```\n\nWith helpers `normalizePath` and `isSameOrChildPath` in share.ts.\n\n**Output patterns:**\n- Text: one line per item to stdout\n- JSON: `{ ok: true, data: { ... } }` or `{ ok: false, error: { code, message } }`\n- `--json` flag for JSON output\n\n**Runtime injection pattern** for testability:\n- `ListRuntime` interface defines external deps\n- `defaultRuntime` for production\n- Commands accept optional runtime param\n\n**TraceMetadata type** has `id` (the external ID), `agentId`, `title`, `directory?`, `sourcePath?`, etc.\n\n**Controller lifecycle:**\n```typescript\nstore = runtime.createStore();\ncontroller = runtime.createController(store, api);\nawait controller.start();\n// use controller\ncontroller?.destroy();\nstore?.close();\n```\n\n## Requirements\n- Command: `traces active --dir `\n- Query SQLite for traces matching the directory\n- Return external IDs (the `id` field on TraceMetadata)\n- Should be fast -- this runs in a git post-commit hook\n- Support `--json` flag\n- Default text output: one external ID per line (for easy parsing by the hook script)\n\n## Key consideration\nThe command needs to be FAST since it runs in a git hook. It probably shouldn't go through the full controller.start() flow (which restores subscriptions and scans adapters). It should just open the SQLite database, query by directory, and return results.\n\nPlan the implementation -- what files to create/modify, what the code looks like, and how to test it.", "subagent_type": "Plan" } ``` ## Assistant **Result** (success): ``` This is very helpful. The `status.ts` command shows a pattern for directly opening the SQLite database in readonly mode without going through the full EventStore/Controller lifecycle. That's exactly the approach we need for the `active` command. Now I have everything I need to design the plan. Here is the implementation plan. --- ## Implementation Plan: `traces active --dir ` ### Design decision: skip the controller The `list` command goes through the full `TraceController.start()` flow, which restores sync subscriptions for all shared traces and iterates over adapters. That's too heavy for a git post-commit hook that runs on every commit. The `status.ts` command shows the right pattern: open the SQLite database directly in readonly mode, run a query, close it. The `active` command should follow this approach. It reads only from the `traces` table, which is populated by prior CLI runs (TUI, `list`, `share`, etc.). No adapter scanning needed. The traces table has `directory` and `source_path` columns but no index on `directory`. For the number of rows a typical user will have (hundreds, maybe low thousands), a full table scan is fine. Adding an index would be premature optimization for something that already returns in single-digit milliseconds. ### Path matching logic Reuse the same logic from `share.ts`: a trace matches a directory if its `directory` or `source_path` is the same path or a child of the given path. The two helper functions (`normalizePath` and `isSameOrChildPath`) are currently local to `share.ts` and should be extracted to a shared utility so both `share.ts` and `active.ts` can use them. ### Files to create **1. `cli/src/commands/active-options.ts`** -- options type and parser ```typescript export interface ActiveCommandOptions { dir?: string; json?: boolean; } export function parseActiveCommandOptions(args: string[]): ActiveCommandOptions { const options: ActiveCommandOptions = {}; for (let i = 0; i < args.length; i += 1) { const arg = args[i]; if (arg === '--dir') { options.dir = args[i + 1]; i += 1; continue; } if (arg === '--json') { options.json = true; continue; } } return options; } ``` **2. `cli/src/commands/active.ts`** -- command implementation The command opens the database readonly, queries all traces, filters by directory match, and outputs the external IDs. No controller, no adapters, no env setup beyond reading the DB path. ```typescript import path from 'path'; import { normalizePath, isSameOrChildPath } from './path-utils'; type ActiveErrorCode = 'INVALID_ARGUMENTS' | 'ACTIVE_FAILED'; type ActiveSuccessPayload = { ok: true; data: { traceIds: string[]; count: number; }; }; type ActiveErrorPayload = { ok: false; error: { code: ActiveErrorCode; message: string; }; }; // Runtime for testability (same pattern as list.ts) export type ActiveRuntime = { queryTracesByDirectory(dir: string): { id: string; directory: string | null; source_path: string | null }[]; writeStdout(message: string): void; writeStderr(message: string): void; }; ``` The core logic: 1. Validate that `--dir` is provided 2. Resolve the dir to an absolute path 3. Open SQLite readonly, query all traces with a non-null `directory` or `source_path` 4. Filter in-app using `isSameOrChildPath` (same as `share.ts`) 5. Output the `id` field (external ID) of each match The default runtime opens the database directly (like `status.ts` does) with `new Database(dbPath, { readonly: true })`, runs a query for traces where directory or source_path is not null, and closes the db. No EventStore instantiation, no migrations, no controller. The query: ```sql SELECT id, directory, source_path FROM traces WHERE directory IS NOT NULL OR source_path IS NOT NULL ``` Then filter in TypeScript using `normalizePath` + `isSameOrChildPath`. **3. `cli/src/commands/path-utils.ts`** -- extracted path helpers ```typescript import path from 'path'; export function normalizePath(value?: string): string | undefined { if (!value) return undefined; return path.resolve(value); } export function isSameOrChildPath(candidate: string, root?: string): boolean { if (!root) return false; if (candidate === root) return true; const rel = path.relative(root, candidate); return rel !== '' && !rel.startsWith('..') && !path.isAbsolute(rel); } ``` ### Files to modify **4. `cli/src/index.ts`** -- register the command Add an `else if (command === 'active')` branch following the existing pattern: ```typescript import { activeCommand } from './commands/active.js'; import { parseActiveCommandOptions } from './commands/active-options.js'; // ... in the if/else chain: } else if (command === 'active') { const options = parseActiveCommandOptions(process.argv.slice(3)); activeCommand(options).then((code) => exitWithFlush(code)); } ``` Also add the `active` command to the help text. **5. `cli/src/commands/share.ts`** -- update imports Replace the local `normalizePath` and `isSameOrChildPath` definitions with imports from `./path-utils`. The function signatures and behavior are identical, so this is a safe refactor. ### Test files to create **6. `cli/src/commands/active-options.test.ts`** Tests for the option parser, following the `list-options.test.ts` pattern: - Parses `--dir` and `--json` - Ignores unknown flags - Handles missing `--dir` value gracefully **7. `cli/src/commands/active.test.ts`** Tests for the command, following the `list.test.ts` pattern with a runtime injection: - Returns matching trace IDs when directory matches - Returns matching trace IDs when source_path matches (child path) - Returns empty when no traces match the directory - Errors when `--dir` is not provided - JSON output wraps IDs in `{ ok: true, data: { traceIds, count } }` - Text output prints one ID per line - Handles database errors gracefully (returns error exit code) **8. `cli/src/commands/path-utils.test.ts`** Tests for the extracted path helpers: - `normalizePath` resolves relative paths - `normalizePath` returns undefined for falsy input - `isSameOrChildPath` returns true for same path - `isSameOrChildPath` returns true for child path - `isSameOrChildPath` returns false for sibling path - `isSameOrChildPath` returns false for parent path ### Output format **Text (default):** ``` abc123-external-id def456-external-id ``` One ID per line, no decoration. The git hook script will read this with a simple `while read` loop. **JSON (`--json`):** ```json {"ok":true,"data":{"traceIds":["abc123-external-id","def456-external-id"],"count":2}} ``` **Error (text):** ``` Active failed (INVALID_ARGUMENTS): --dir is required. ``` **Error (JSON):** ```json {"ok":false,"error":{"code":"INVALID_ARGUMENTS","message":"--dir is required."}} ``` ### Runtime injection for testing The `ActiveRuntime` interface abstracts database access so tests can inject trace data without touching SQLite: ```typescript export type ActiveRuntime = { queryTracesByDirectory(): { id: string; directory: string | null; source_path: string | null }[]; writeStdout(message: string): void; writeStderr(message: string): void; }; ``` The default runtime does the readonly SQLite open/query/close inline, same as `status.ts`. The test runtime returns canned rows. ### Performance characteristics The command does: 1. Resolve the DB path from env/defaults (~0ms) 2. Open SQLite in readonly mode (~1ms) 3. Query traces table (~1ms for hundreds of rows) 4. Filter in TypeScript (~0ms) 5. Print to stdout (~0ms) 6. Close db (~0ms) Total wall time should be under 10ms for typical databases, well within git hook tolerance. No network calls, no adapter scanning, no controller lifecycle. ### Sequencing 1. Create `path-utils.ts` and `path-utils.test.ts` first (standalone, no dependencies) 2. Update `share.ts` to import from `path-utils` instead of defining locally (refactor, tests should still pass) 3. Create `active-options.ts` and `active-options.test.ts` 4. Create `active.ts` and `active.test.ts` 5. Register in `index.ts` and update help text 6.

The exact default path on macOS\n\nRead the actual source files.", "subagent_type": "Explore" } ``` ## Assistant **Result** (success): ``` Perfect! I've found all the relevant code. Let me provide you with a comprehensive answer about how the traces CLI determines its SQLite database path. ## Database Path Resolution The traces CLI determines its SQLite database path through a clear multi-step process: ### 1. EventStore Constructor (`cli/src/core/event-store.ts`, lines 55-75) The `EventStore` class has the definitive logic: ```typescript constructor(options: { dbPath?: string; maxEventBytes?: number } = {}) { const baseDir = path.join(os.homedir(), '.traces'); if (!fs.existsSync(baseDir)) { fs.mkdirSync(baseDir, { recursive: true, mode: 0o700 }); } else { try { fs.chmodSync(baseDir, 0o700); } catch {} } const defaultDbName = 'traces.db'; const envDbName = process.env.TRACES_EVENTSTORE?.trim(); const dbName = envDbName || defaultDbName; const resolvedDbPath = path.isAbsolute(dbName) ? dbName : path.join(baseDir, dbName); // Legacy migration: events.db -> traces.db if (!envDbName || dbName === defaultDbName || resolvedDbPath === path.join(baseDir, defaultDbName)) { const legacyPath = path.join(baseDir, 'events.db'); if (fs.existsSync(legacyPath) && !fs.existsSync(resolvedDbPath)) { fs.renameSync(legacyPath, resolvedDbPath); } } const dbPath = options.dbPath ?? resolvedDbPath; this.db = new Database(dbPath); fs.chmodSync(dbPath, 0o600); ``` ### 2. How Commands Create EventStore Looking at `list.ts` (line 52): ```typescript const defaultRuntime: ListRuntime = { applyEnv: () => applyDefaultEnv(), createStore: () => new EventStore(), // No options passed - uses defaults // ... }; ``` Similarly in `status.ts` (lines 12-17), there's a standalone `getDatabasePath()` function that replicates the same logic: ```typescript function getDatabasePath(): string { const baseDir = getTracesDir(); const envDbName = process.env.TRACES_EVENTSTORE?.trim(); const dbName = envDbName || "traces.db"; return path.isAbsolute(dbName) ? dbName : path.join(baseDir, dbName); } ``` ### 3. Environment Variables and Configuration Only one environment variable controls the database path: - **`TRACES_EVENTSTORE`** - If set, can be: - An absolute path (used as-is) - A relative filename (joined with `~/.traces`) - If not set, defaults to `traces.db` Other environment variables documented in `status.ts` (lines 138-150) are: - `TRACES_HTTP_URL` - API endpoint - `TRACES_API_URL` - Convex API - `TRACES_CONFIG_DIR` - Auth config location ### 4. Default Path on macOS On macOS, with no `TRACES_EVENTSTORE` override: **`~/.traces/traces.db`** Which expands to: **`/Users/[username]/.traces/traces.db`** The directory is created with mode `0o700` (rwx------) and the database file with mode `0o600` (rw-------). ### 5. Legacy Migration The code also handles a legacy migration path: if `events.db` exists in `~/.traces/` and the new `traces.db` doesn't, it automatically renames `events.db` to `traces.db` on first startup (lines 67-72 in event-store.ts). agentId: a216dd5f2fec95b17 (for resuming to continue this agent's work if needed) total_tokens: 28846 tool_uses: 3 duration_ms: 10439 ``` ## Assistant Good. The DB is at `~/.traces/traces.db` by default. The hook just needs to open that with sqlite3, query for traces matching the working directory, and write git notes. ## Assistant ### Tool: Write **Args:** ```json { "content": "# Git hook demo\n\n## Context\n\nGet a working demo of trace IDs being written to git notes on commit.
