Implement the following plan:
traces sync commandtraces share pushes a trace to the server, but there's no way to pull one back down. When someone sees a trace ID in a git note or shared URL, they can view it in the browser but can't get it into their local ~/.traces/traces.db for the TUI. traces sync <externalId> closes that loop: fetch trace metadata + messages from the API, convert to CLI events, store locally.
Reuse existing GET endpoints, no new export route. GET /v1/traces/:id and GET /v1/traces/:id/messages?includeParts=true already return everything we need. Two sequential calls, no new API surface.
Reverse transform in the CLI. The CLI has buildMessagePayload (events -> API messages). We add the inverse: API messages+parts -> TraceEvents. Lives in api.ts alongside the forward transform.
Store as synced trace. The trace gets upserted into EventStore with the remote's externalId as the local trace ID (same convention as share). It won't have sourcePath or directory since those are local-only. sharedUrl gets set from the frontend URL so the TUI shows it as shared.
cli/src/services/api.tsAdd two fetch methods and the reverse transform:
New types:
Reverse transform — buildEventFromMessage(msg: RemoteMessage, index: number): TraceEvent | null:
text + role user -> UserMessageEventtext + role assistant -> AgentTextEventthinking -> AgentThinkingEventtool_call -> ToolCallEventtool_result -> ToolResultEventerror -> ErrorEventcli/src/commands/sync.ts (new)Follows the same runtime-injection pattern as share.ts and list.ts.
Flow:
api.getTrace(externalId) — fetch metadataapi.getTraceMessages(externalId) — fetch messages with partsstore.upsertTrace(metadata)store.replaceEvents(externalId, events)cli/src/commands/sync-options.ts (new)Positional arg for externalId, --json flag.
cli/src/index.tsAdd sync command to the dispatch chain.
cli/src/commands/sync.test.ts (new)Using runtime injection to mock API and store:
{ ok, data: { traceId, messageCount, ... } }cli/src/services/api.ts # getTrace, getTraceMessages, buildEventFromMessage, Api type cli/src/commands/sync.ts # NEW — sync command cli/src/commands/sync-options.ts # NEW — options parser cli/src/commands/sync.test.ts # NEW — tests cli/src/index.ts # command dispatch
cd cli && bun test — all tests passtraces share --trace-id <id> --json — note the externalIdtraces sync <externalId> --json — confirm it stores and outputs correctlytraces list --json — confirm synced trace appears in the listIf you need specific details from before exiting plan mode (like exact code snippets, error messages, or content you generated), read the full transcript at: /Users/andrew/.claude/projects/-Users-andrew-code-traces-traces/3784f20e-e940-4c28-9de5-1fc7cade0f35.jsonl

633 pass

Ran 635 tests across 36 files. [24.59s]One test failure in my code: store_is_closed_on_error. The issue is that the store is only created inside the try block, after getTrace and getTraceMessages succeed. But in the test, getTraceMessages throws, which happens after the store is created (looking at the code flow more carefully)...
Wait, let me re-read my sync.ts code:
The store is only created AFTER the API calls. If getTraceMessages throws, the store was never created, so store?.close() is a no-op. I can either move the store creation before the API calls, or adjust the test to throw after the store exists.
Option 1 makes more sense—I should create the store before the try block or at the start of it, so the finally block can properly close it even if the API calls fail. Though creating it before we know if we need it wastes resources, the safer resource-management pattern is worth it.
Looking at the test setup, it mocks both createStore and createApi. The issue is that getTraceMessages throws before store = runtime.createStore() ever runs, so the store is never created and storeClosed never gets set to true.
The fix is straightforward—I'll move the store creation earlier, before the API calls happen.
One test failure - the store gets created after the API calls, so if the API call throws, the store never gets created. Let me fix the sync command to create the store earlier.
Also fix the finally block to not use optional chaining since store is always defined now:
Now let me check what the other test failure was. Let me look at the output more carefully - it said "2 fail, 1 error". Let me run just the sync tests first, then the full suite.

feat(cli): add traces sync command to pull remote traces locally
Adds `traces sync <externalId>` which fetches a trace's metadata and
messages from the API, converts them back to CLI events, and stores
them in the local database. This lets users pull down traces they've
seen in the browser or found via git notes.

Store git context (remote URL, branch, commit SHA) on traces at discovery time so shared traces carry repo provenance without needing to re-derive it from the directory path. Also adds `traces sync <id>` to pull remote traces into the local database.
Trace: https://www.traces.com/s/jn7evx597bm1gw57vnwg9n7z9d81q896
**Git metadata (CLI):**
- `git.ts` resolves remote URL, branch, and HEAD ref via local git commands with a per-directory TTL cache (30s, bounded at 200 entries)
- SQLite migration v4 adds `git_remote_url`, `git_branch`, `git_ref` columns with idempotent column-exists guards
- EventStore upsert uses COALESCE so re-upserts without git fields don't clobber existing values
- The claude-code adapter populates git fields at scan time
- Sync payload carries the three fields to the API
**Git metadata (API):**
- Three optional string fields on `TraceCreateRequest`, `TraceUpsertRequest`, and `TraceDetail` in the OpenAPI spec
- Convex schema, validators, internal sync mutation, and service layer all updated
- Added `by_gitRemoteUrl` index for future repo-scoped queries
**`traces sync` command:**
- `traces sync <externalId>` fetches trace metadata and messages from `GET /v1/traces/:id` and `GET /v1/traces/:id/messages?includeParts=true`, converts API messages+parts back to CLI events via `buildEventFromMessage` (inverse of `buildMessagePayload`), and upserts into the local EventStore
- Supports `--json` for machine-readable output
- Runtime-injection pattern matching share/list for testability
**Why flat fields instead of normalized tables:**
Convex has no foreign keys or JOINs. Normalized repo/branch tables would require multiple sequential queries on every trace read and add complexity to the sync path for marginal benefit at current scale. If we later need to query across repos or attach repo-level metadata, we can add a `repositories` table and backfill the foreign key without breaking the existing fields.
**Tests:** 34 new/updated CLI tests for git resolution, migration v4 idempotency, EventStore round-trip. 15 new tests for sync command (validation, auth, event conversion, error paths, store cleanup). Full API suite passes (567/567).

Updated. Checked off traces sync and the GET endpoint verification, removed the separate export endpoint item (since the existing messages endpoint already serves that purpose), and consolidated the import items.
ok, so shall we look at Git-linked trace discovery on startup -- if in a git repo, read refs/notes/traces from recent refs, fetch any unknown trace IDs from the API, show them in the list
Entered plan mode. You should now focus on exploring the codebase and designing an implementation approach. In plan mode, you should: 1. Thoroughly explore the codebase to understand existing patterns 2. Identify similar features and architectural approaches 3. Consider multiple approaches and their trade-offs 4. Use AskUserQuestion if you need to clarify the approach 5. Design a concrete implementation strategy 6. When ready, use ExitPlanMode to present your plan for approval Remember: DO NOT write or edit any files yet. This is a read-only exploration and planning phase.
Perfect! Now I have all the information I need to provide a comprehensive overview. Let me create a summary based on all the code I've read:
## Summary: TUI Startup Flow and Trace Discovery Architecture
Based on my exploration of the codebase, here's the complete flow from TUI startup through trace discovery:
### 1. TUI Startup Path
**Entry point: `cli/src/tui/app.tsx`**
- The `startTui()` function (line 123) initializes the OpenTUI renderer with specific signal handling
- Renders the `App()` component which is a thin composition layer
**App component (lines 43-111):**
- Calls `createAppState()` to initialize all application state
- Wires up keyboard handling via `setupKeyboard()`
- Composes UI components: Header, ListView, DetailView, Footer, Dialogs, Overlays
- No business logic—purely structural composition
### 2. App State Initialization: `useAppState.ts`
This is where the magic happens. The `createAppState()` hook (lines 237-1438):
**Infrastructure setup (lines 336-352):**
```
EventStore (SQLite database) -> TraceController -> AdapterRegistry
```
- Creates an `EventStore` instance (SQLite at `~/.traces/traces.db`)
- Creates an `Api` instance for remote sync
- Creates a `TraceController` with the store, registry, and API
- Subscribes to controller events for UI state updates
**Initialization effect (lines 1166-1216):**
1. Loads config (local defaults + remote overrides)
2. Calls `controller.start()` to restore shared trace subscriptions
3. Calls `controller.list()` to fetch initial traces
4. Sets loading state to false and triggers message count refresh
5. Sets up a periodic refresh interval (REFRESH_INTERVAL_MS)
### 3. TraceController: `cli/src/core/trace-controller.ts`
The controller is the main orchestrator:
**`start()` method (lines 68-79):**
- Restores subscriptions for shared traces from the stored list
- Idempotent—safe to call multiple times
**`list()` method (lines 84-99):**
- Returns stored traces if they exist (and triggers background refresh)
- If empty and `seedIfEmpty` is true, calls `indexer.refresh()` to scan adapters
- Returns traces as an array of `Trace` objects
**Key insight:** Traces come from two sources:
1. **Stored traces** in EventStore (fastest, stale data possible)
2. **Live adapter scans** via the TraceIndexer (slower, fresh data)
### 4. Adapter Discovery: `cli/src/adapters/index.ts`
**Adapter registry pattern:**
- Global `registry` instance of `AdapterRegistry`
- 7 adapters registered: Claude Code, Cursor, OpenCode, Codex, Gemini CLI, Pi, Amp
- Auto-initializes on import via `initializeAdapters()`
**AdapterRegistry methods (adapter.ts, lines 201-328):**
- `getAvailable()`: Filters to only adapters present on system
- `getTraces()`: Calls `adapter.getTraces()` on each available adapter and merges results
- Each adapter must implement the `TraceAdapter` interface
### 5. TraceIndexer: `cli/src/core/trace-indexer.ts`
Responsible for discovering and caching traces:
**`refresh()` method (lines 23-37):**
- Gets all available adapters
- For each adapter, calls either:
- `adapter.getTraceIndexBatch()` (incremental, paginated discovery)
- `adapter.getTraces()` (full scan)
- Upserts discovered traces into the EventStore
- Caches the cursor position and last scan time
**Optimization:** Skips non-incremental scans if they ran recently (NON_INCREMENTAL_SCAN_INTERVAL_MS = 60 seconds)
### 6. Git Information: `cli/src/core/git.ts`
The git utilities already exist:
```typescript
export interface GitInfo {
remoteUrl?: string;
branch?: string;
ref?: string;
}
export function resolveGitInfo(directory: string): GitInfo
```
**Functionality:**
- `git config --get remote.origin.url` → remote URL
- `git rev-parse --abbrev-ref HEAD` → branch name
- `git rev-parse HEAD` → current commit SHA
**Caching:** Results cached for 30 seconds per directory (gitInfoCache)
### 7. TraceMetadata Fields
TraceMetadata stored in EventStore includes (cli/src/types.ts, lines 113-127):
```typescript
interface TraceMetadata {
id: string;
agentId: AgentId;
title: string;
preview: string;
timestamp: number;
directory?: string;
sourcePath?: string;
sharedUrl?: string;
sharedVisibility?: TraceVisibility;
modelId?: ModelId;
gitRemoteUrl?: string; // ← Already supported!
gitBranch?: string; // ← Already supported!
gitRef?: string; // ← Already supported!
}
```
**Already present:** Git metadata fields are in the schema!
### 8. EventStore Schema
The database stores traces with git columns (event-store.ts, lines 83-98):
```sql
git_remote_url TEXT,
git_branch TEXT,
git_ref TEXT,
```
---
## Where Git-Note-Based Discovery Would Plug In
Based on this architecture, here's where git notes trace discovery would integrate:
**Option A: New Adapter** (cleanest)
- Create `cli/src/adapters/git-notes/v1.ts`
- Implements `TraceAdapter` interface
- `getTraces()` scans for git notes with trace references
- Register in `cli/src/adapters/index.ts`
- Adapter discovers traces from git notes, enriches with git metadata automatically
**Option B: Existing Adapter Enhancement**
- Modify one of the existing adapters (e.g., Claude Code) to also scan git notes
- Less clean but faster if tightly coupled to one agent
**Option C: TraceIndexer Enhancement**
- Add a separate discovery path in the indexer for git notes
- Would require refactoring the indexer to handle non-adapter trace sources
---
## Current Flow Summary
```
startTui()
├─> createAppState()
│ ├─> EventStore (SQLite) ← traces already cached here
│ ├─> AdapterRegistry (7 adapters auto-initialized)
│ ├─> TraceController
│ └─> controller.start() + controller.list()
│ └─> If empty: indexer.refresh()
│ ├─> adapters.getAvailable()
│ └─> For each adapter:
│ └─> adapter.getTraces() or getTraceIndexBatch()
│ └─> Discovers traces, upserts to EventStore
└─> UI renders traces, periodically refreshes
```
**Git metadata is already captured** in adapters when they discover traces (if adapters call `resolveGitInfo()`). The infrastructure is ready—it just needs adapters to populate those fields.

## Summary of Git Notes and Trace ID Integration
Based on my search through the codebase, here's exactly how trace IDs are written to git notes and what data structure they use:
### Git Notes Format
**Location:** Git notes are stored under the ref `refs/notes/traces` (custom namespace)
**Format - Two Types of Entries:**
The post-commit hook writes lines in this format:
1. **With shared URL (already shared trace):**
```
traces:<trace-id> <shared-url>
```
Example:
```
traces:abc123def456 https://traces.sh/s/xyz789
```
2. **Without shared URL (unshared trace):**
```
traces:<trace-id>
```
Example:
```
traces:abc123def456
```
**Multiple notes:** Each note appended to a commit can contain multiple trace lines. The hook uses `git notes --ref=traces append --file=-` which preserves existing notes from collaborators and adds new lines.
**File:** `/Users/andrew/.traces/hooks/post-commit` (lines 55-72)
### How the Hook Works
1. **Query database for traces** (lines 40-47):
- Queries `~/.traces/traces.db` for traces matching the current directory
- Only includes traces created since the previous commit (to avoid attaching all historical traces)
- Queries: `SELECT id, shared_url FROM traces WHERE directory = ? AND timestamp >= ?`
2. **Build note content** (lines 59-70):
- For each matching trace, if it has a `shared_url`, writes: `traces:${id} ${url}`
- If no `shared_url` yet, writes: `traces:${id}` (bare)
- Unshared IDs are collected for background sharing
3. **Append to git notes** (line 72):
- `git notes --ref=traces append --file=- HEAD`
- Preserves existing notes from other collaborators
4. **Background async work** (lines 74-95):
- For unshared traces, runs `traces share --trace-id` to get a URL
- Updates the note by replacing bare `traces:${id}` with `traces:${id} ${url}`
- Pushes notes to remote if configured
### Trace Metadata in CLI Database
The CLI stores git metadata in SQLite (added in migration v4, `/Users/andrew/code/traces/traces/cli/src/core/migrations.ts` lines 76-91):
**Schema columns:**
- `git_remote_url` — Git remote origin URL
- `git_branch` — Current branch name (undefined in detached HEAD)
- `git_ref` — Full commit SHA (40 hex chars)
**How it's populated:**
The Claude Code adapter (`cli/src/adapters/claude-code/v1.ts` lines 140-145) calls `resolveGitInfoCached()` at discovery time:
```typescript
if (trace.directory) {
const gitInfo = resolveGitInfoCached(trace.directory);
trace.gitRemoteUrl = gitInfo.remoteUrl;
trace.gitBranch = gitInfo.branch;
trace.gitRef = gitInfo.ref;
}
```
**Git resolution** (`cli/src/core/git.ts`):
- `remoteUrl`: `git config --get remote.origin.url`
- `branch`: `git rev-parse --abbrev-ref HEAD` (clears to undefined if result is "HEAD")
- `ref`: `git rev-parse HEAD` (full SHA)
Results are cached per directory for 30 seconds to avoid redundant `git` command calls.
### API Sync (backend)
The API accepts these three fields in trace creation/update (`api/convex/internal/sync.ts` lines 64-66):
```typescript
gitRemoteUrl: v.optional(v.string()),
gitBranch: v.optional(v.string()),
gitRef: v.optional(v.string()),
```
They're stored flat on the `traces` table (no normalization) and synced with `COALESCE` semantics: only first write wins, re-upserting doesn't overwrite.
### TypeScript Types
**CLI types** (`cli/src/types.ts` lines 113-127):
```typescript
export interface TraceMetadata {
// ...
gitRemoteUrl?: string;
gitBranch?: string;
gitRef?: string;
}
```
**EventStore table** (`cli/src/core/event-store.ts` lines 84-97):
All three columns are `TEXT` nullable in the schema.
### Key Design Notes
1. **Git notes are collaborative** — Multiple developers' traces can appear on the same commit
2. **Async URL backfill** — Hook doesn't block; bare trace IDs get URLs filled in asynchronously
3. **No re-sharing** — Once a trace has a URL, it's never re-shared (COALESCE preserves it)
4. **Flat schema** — Git metadata stored directly on traces table, not normalized, because Convex has no JOINs
5. **Discovery-time capture** — Git info resolved when traces are discovered, not retroactively
This design allows the frontend/API to show repository context for every trace without re-querying git or maintaining state about which traces belong to which repos.

<usage>total_tokens: 52831
tool_uses: 32
duration_ms: 51717</usage>The user wants me to consider an additional feature: listing trace IDs for a repo from the web API. This would be useful so that when you're in a git repo, you can ask the API "what traces exist for this repo?" without having to read git notes locally. This could be based on the gitRemoteUrl field that's now stored on traces.
Let me think about this in the context of the git-linked trace discovery feature:
Read git notes from local repo → get trace IDs attached to recent commits
Also query API by gitRemoteUrl → get all traces for this repo that have been shared
Merge the two sets, sync any unknown trace IDs
The traces table already has a by_gitRemoteUrl index from PR #253, so I could add a query endpoint like GET /v1/traces?gitRemoteUrl=... to fetch traces for a given repository.
Good call. That would give you trace discovery even without git notes set up locally. Let me check what's already in place for that.
Perfect. Now I have all the information I need. Let me create a comprehensive summary: ## Summary: Git Remote URL Query Infrastructure Based on my analysis of the codebase, here's what exists and what's missing for querying traces by git remote URL: ### What Already Exists 1. **Database Schema (schema.ts, line 146)** - A `by_gitRemoteUrl` index is defined on the traces table - The traces table has three git-related fields: `gitRemoteUrl`, `gitBranch`, and `gitRef` (lines 137-139) 2. **Data Model** - Traces can be created/updated with git metadata (`gitRemoteUrl`, `gitBranch`, `gitRef`) - This is supported in both `TraceCreateRequest` and `TraceUpsertRequest` API types (lines 192-215 in types.gen.ts) - The `TraceDetail` response includes git metadata fields (lines 171-182 in types.gen.ts) 3. **Service Layer** - The `traces.ts` service layer accepts git metadata in `createTrace()`, `upsertTrace()`, and `updateTrace()` operations - Git metadata is mapped and returned in `mapTraceDetail()` function (lines 35-49 in traces.ts) ### What Does NOT Exist Yet 1. **No Query Function by gitRemoteUrl** - The `internal/traces.ts` file has no query function like `_listByGitRemoteUrl` or `_getByGitRemoteUrl` - The index exists but is never used by any query function 2. **No HTTP Route for Filtering by gitRemoteUrl** - The `GET /v1/traces` endpoint (lines 16-30 in http/v1/traces.ts) accepts only a `limit` parameter - No support for query parameters to filter by `gitRemoteUrl` - The `GET /v1/namespaces/:slug/traces` endpoint (in namespaces.ts, lines 65-75) also accepts only `limit` 3. **No Service Layer Functions** - No service function in `services/traces.ts` to query traces by gitRemoteUrl ### The Full Data Flow The infrastructure that's missing would need to: 1. Add `_listByGitRemoteUrl` query in `internal/traces.ts` that uses the existing index 2. Add a service layer function in `services/traces.ts` to wrap this query 3. Add a new HTTP route or extend the existing `GET /v1/traces` route to accept a `gitRemoteUrl` query parameter 4. Properly handle authorization (since traces have visibility/namespace scoping) The index is ready to go, but the query functions and HTTP layer to access it haven't been implemented yet. agentId: a22270128a2cfb11b (for resuming to continue this agent's work if needed) <usage>total_tokens: 47259 tool_uses: 15 duration_ms: 25812</usage>
Good, the by_gitRemoteUrl index already exists but nothing queries it yet. Now let me read the key files I need for the plan.
Let me start by understanding the existing codebase structure, particularly the files mentioned in the plan. I need to read several files to understand the patterns before implementing.
Now let me read the hook file and the useAppState.ts to understand the TUI startup sequence and where we'd plug in.

User has answered your questions: "For the API endpoint to list traces by repo, should it be scoped to the user's namespace (only traces they have access to) or also include public/direct traces from other namespaces in the same repo?"="Namespace-scoped only", "When should the CLI fetch repo traces from the API?"="TUI startup only". You can now continue with the user's answers in mind.
Now let me look at the existing listTraces on the API to see its response shape, and check if there's a way to filter by gitRemoteUrl.
Good. Now let me also check the Convex HTTP shared helpers and the jsonV1 pattern to understand how to add a query parameter to the existing traces GET route.

114-}I have everything I need. Let me write the plan.
Now let me check the PartType values and look at an existing test to understand patterns.
Right, namespace scoping is the safe default. Now let me write the plan.
The user doesn't want to proceed with this tool use. The tool use was rejected (eg. if it was a file edit, the new_string was NOT written to the file). STOP what you are doing and wait for the user to tell you how to proceed.
Let me check the PartType values and look at existing tests for patterns.
Perfect! Now I have a comprehensive understanding of the testing patterns. Let me create a summary report.
## Testing Patterns Found in `/Users/andrew/code/traces/traces/cli/src/commands/`
I've analyzed the test files and found consistent patterns across the test suite. Here's what I discovered:
### Test Files in the Directory
There are 9 test files:
- `/Users/andrew/code/traces/traces/cli/src/commands/share.test.ts` (900 lines - comprehensive)
- `/Users/andrew/code/traces/traces/cli/src/commands/list.test.ts` (162 lines)
- `/Users/andrew/code/traces/traces/cli/src/commands/status.test.ts` (124 lines)
- `/Users/andrew/code/traces/traces/cli/src/commands/auth.test.ts` (132 lines)
- `/Users/andrew/code/traces/traces/cli/src/commands/login.test.ts`
- `/Users/andrew/code/traces/traces/cli/src/commands/setup.test.ts`
- `/Users/andrew/code/traces/traces/cli/src/commands/share-options.test.ts`
- `/Users/andrew/code/traces/traces/cli/src/commands/setup-options.test.ts`
- `/Users/andrew/code/traces/traces/cli/src/commands/list-options.test.ts`
### Core Testing Patterns
**1. Test Framework & Setup**
- Uses `bun:test` with `describe`, `test`, `expect`, `beforeEach`, `afterEach`
- Can also use `mock` from `bun:test` for function mocking
**2. Console Capture Pattern (Most Common)**
```typescript
let originalConsoleLog: typeof console.log;
let originalConsoleError: typeof console.error;
let logOutput: string[];
let errorOutput: string[];
beforeEach(() => {
originalConsoleLog = console.log;
originalConsoleError = console.error;
logOutput = [];
errorOutput = [];
console.log = (...args: unknown[]) => {
logOutput.push(args.map((arg) => String(arg)).join(" "));
};
console.error = (...args: unknown[]) => {
errorOutput.push(args.map((arg) => String(arg)).join(" "));
};
});
afterEach(() => {
console.log = originalConsoleLog;
console.error = originalConsoleError;
logOutput = [];
errorOutput = [];
// Clean up env vars
delete process.env.VAR_NAME;
});
```
**3. Runtime Mock Factory Pattern**
Commands receive a "Runtime" object (e.g., `ShareRuntime`, `ListRuntime`). Tests create mocks via factory functions:
```typescript
function createRuntime(overrides: Partial<ShareRuntime> = {}): ShareRuntime {
const runtime: ShareRuntime = {
applyEnv: () => {},
createStore: () => ({ close: () => {} }) as any,
createApi: () => ({ isAuthenticated: () => true, isConfigured: () => true }) as any,
createController: () => ({
start: async () => {},
list: async () => defaultTraces,
share: async () => ({ url: "https://www.traces.com/s/abc123" }),
destroy: () => {},
}) as any,
writeStdout: (message: string) => { logOutput.push(message); },
writeStderr: (message: string) => { errorOutput.push(message); },
...overrides,
};
return runtime;
}
```
**4. Test Organization with Comments**
Tests are grouped into logical sections with clear comment dividers:
```typescript
// =========================================================================
// Share command: selector validation
// =========================================================================
test("share_requires_selector_and_returns_invalid_arguments_json", async () => {
// ...
});
```
Sections seen:
- Selector validation
- Success paths
- Validation / error handling
- Environment variable hints
- JSON output tests
- Human-readable output tests
- Cleanup tests
**5. Exit Code Convention**
- `expect(code).toBe(0)` - success
- `expect(code).toBe(1)` - runtime error
- `expect(code).toBe(2)` - invalid arguments
**6. JSON Output Testing**
For JSON mode tests, parse error/log output:
```typescript
const payload = JSON.parse(errorOutput[0] ?? "{}");
expect(payload.ok).toBe(false);
expect(payload.error.code).toBe("INVALID_ARGUMENTS");
expect(payload.error.message).toContain("expected text");
```
**7. Test Naming Convention**
- Prefix with command name: `share_`, `list_`, etc.
- CamelCase for the rest: `share_by_trace_id_returns_success_json_with_share_url`
- Describes behavior and expected result
**8. Cleanup Requirements (Critical)**
- afterEach cleans up: console restores, output arrays reset, env vars deleted
- Some tests also handle file cleanup with `fs.rmSync(tempDir, { recursive: true, force: true })`
**9. Environment Variable Testing**
- Tests set/delete process.env vars in beforeEach/afterEach
- Example: `TRACES_CURRENT_TRACE_ID`, `TRACE_ID`, `TRACES_CURRENT_SOURCE_PATH`, `TRACES_CURRENT_AGENT`
**10. Temporary File Pattern (for file system tests)**
```typescript
const tempDir = fs.mkdtempSync(path.join(os.tmpdir(), `traces-auth-cmd-test-${Date.now()}`));
// ... use tempDir ...
fs.rmSync(tempDir, { recursive: true, force: true });
```
### The Share Command Test as Reference
The `/Users/andrew/code/traces/traces/cli/src/commands/share.test.ts` is the most comprehensive (900 lines) and covers:
- Selector validation (trace-id, source-path, cwd requirements)
- Success paths (various selection modes)
- Error paths (auth required, trace not found, upload failed, API not configured)
- Follow mode (waiting for stop signals)
- Environment variable hints
- List mode with filtering and sorting
- JSON and human-readable output
- Cleanup verification
This file should serve as a template for writing new command tests.

</persisted-output>Let me find the actual API route handler for trace detail and messages GET endpoints.
Found 1 file api/convex/http/v1/traces.ts
No files found
Now let me check the API response shape for getTrace and listMessages.
Now let me check the API types for the response shapes.
Now I have a thorough understanding of all the pieces. Let me implement the changes:
API client (cli/src/services/api.ts) - Add getTrace, getTraceMessages, buildEventFromMessage functions, and update the Api type
Sync command (cli/src/commands/sync.ts) - New file
Sync options (cli/src/commands/sync-options.ts) - New file
CLI entry point (cli/src/index.ts) - Add sync command
Tests (cli/src/commands/sync.test.ts) - New file
API response shapes - The trace endpoint returns trace metadata like id, external ID, title, and agent details, while the messages endpoint returns an array of message resources with role, content, and model information
. Each message can have multiple parts (text, thinking, tool calls, etc.) that determine how to transform them into events.
Reverse transformation logic - I need to map message parts back to their corresponding event types: text content from users becomes UserMessageEvent, assistant text becomes AgentTextEvent, thinking blocks map to AgentThinkingEvent, and tool interactions map to their respective events, with a fallback to textContent if parts aren't available.
Extended trace metadata - The TraceDetail response also includes modelName and messageCount fields that I'll need to incorporate.
Now I'm ready to implement the transformation layer using the OpenAPI types from the shared package.
For the Api interface, I need to add getTrace and getTraceMessages methods that the sync command will call directly to fetch remote data, following the same runtime injection pattern used in other commands.
I'm defining local types for RemoteTraceDetail and RemoteMessage that align with the API response structure, then I'll implement the bidirectional transformations between the API format and the event-based format. I need to keep the changes focused, so I'll add getTrace and getTraceMessages directly to the Api type since that's what the sync command expects to call. Now I'm writing the function that converts remote messages into trace events, handling the message parts and building out the event structure.
Writing event conversion logic... Writing the message parsing logic... Setting up the sync command types and runtime... Now I'm fetching the trace metadata and messages from the API, converting those messages into events, and then building a shared URL for the trace.
I'm constructing the trace metadata object with all the relevant details like the agent ID, title, preview from the first event, timestamp, and the shared URL, along with git information if available.
Now I'm persisting this data locally by creating a store, upserting the trace metadata, and replacing the events. If everything succeeds, I'll return a success response with the trace ID and message count. For errors, I'm handling the specific case where the trace isn't found separately, then catching any other failures and returning an appropriate error message. Finally, I'm making sure to close the store in the cleanup phase.
I need to figure out the imports—specifically where buildEventFromMessage comes from in api.ts and how it fits with the forward transform. For the preview field in the trace metadata, I can keep it straightforward by extracting text from the first event in the synced data. I'm also thinking through what the RemoteTraceDetail and RemoteMessage structures look like based on the API responses to make sure I'm mapping the data correctly. Now I'm defining the TypeScript types for the trace and message data structures, starting with the remote trace detail type that includes all the metadata fields like visibility, timestamps, and git information.
Defining the message type...
Now I need to implement the API functions to fetch trace data and messages from the remote service.
Adding these to the Api interface and wiring them up in createApi...
For the sync-options parser...
Setting up the test file...
Now I'm thinking about the getPreview helper function that extracts a preview string from trace events. I'll handle the different event types by returning the first 200 characters of their content, and for tool calls I need to figure out what makes sense to preview.
Actually, I realize I don't need a separate helper function for this—I can just inline the preview extraction logic directly where it's needed.
Now I'm refining the Api type definition and need to be thoughtful about what methods to include, making sure I'm not overcomplicing the interface.
Extending the Api type...
I need to check if adding these new methods will break existing code—the share and list commands create TraceController instances that depend on Api, and while test mocks cast to any so they'll be fine, the actual createApi() implementation will need to provide these methods. Actually, looking at the sync command more carefully, it doesn't need TraceController at all since it works directly with the EventStoreApi and Api without local subscriptions or scanning.
The sync flow is straightforward: fetch the remote trace and messages through the API, convert those messages to TraceEvents, then upsert the metadata and replace the events in the local store before outputting success.
Now I'm ready to implement this.
One thing to verify—the remote agentId comes as a string from the OpenAPI types, but TraceMetadata expects an AgentId type. Since AgentId already includes 'manual' as a valid value and the remote trace's agentId is set when created, I can safely cast it and default to 'manual' if it's undefined.
Writing the implementation now.
