Here's the overview: ## Traces — Platform for Sharing AI Coding Agent Traces **Traces** is a platform where developers can share, discover, and discuss traces (conversation logs) from AI coding agents like Claude Code, Cursor, Codex, Gemini CLI, and others. Think of it as a social platform for AI coding sessions. --- ### Architecture (Monorepo with 4 packages) | Package | Tech | Purpose | |---------|------|---------| | **`api/`** | Self-hosted Convex + HTTP Actions | Backend — data model, REST API, auth, real-time queries | | **`frontend/`** | Next.js 15 + React 19 + Tailwind v4 | Web app — browse, view, and share traces | | **`cli/`** | Bun + OpenTUI + Solid.js + SQLite | Terminal UI — captures traces from local agents and syncs them | | **`packages/shared/`** | TypeScript | Shared types, schemas, and Convex function references | --- ### Core Data Model ``` namespaces (workspace/profile scope — individual or org) ├── namespaceMemberships (users + roles) ├── namespaceInvites (join codes) ├── agents (namespace-scoped bots with API keys) └── traces (AI conversation metadata) └── messages (user/assistant/system, ordered) └── parts (text, thinking, tool_call, tool_result, error) ``` ### How It Works End-to-End 1. **CLI discovers traces** — 10 adapters read agent-specific storage formats (JSONL, SQLite, JSON) from local directories for Claude Code, Cursor, Codex, Gemini CLI, Amp, Cline, etc. 2. **CLI syncs to API** — Events are transformed from the CLI's flat event-sourced format into the API's relational messages+parts model 3. **Frontend renders traces** — Message classification pipeline normalizes 80+ tool name variants across agents into 14 canonical types, then specialized React components render each one (terminal commands, file edits with diffs, search results, etc.) ### Key Technical Patterns - **Dual auth channels**: Cookie sessions (REST API) + short-lived access tokens (Convex reactive queries) - **GitHub OAuth** for both web and CLI (with device flow for CLI) - **3-tier visibility**: private → direct (link-only) → public (discoverable) - **Server-then-client hydration**: RSC preloads trace data, client hooks take over for real-time updates - **Rate limiting + CSRF** on all state-changing endpoints - **Custom auth system** (no third-party auth provider) with SHA-256 token hashing ### Development ```bash bun install # Install everything bun run dev # Start API + Frontend bun run dev:cli # Start CLI in dev mode bun run test # Run all tests ``` Let me know what you'd like to work on!‍‍ ## User What tools do u have access to ## Assistant I'm Slate, built by Random Labs. Here's what I can do: - **Read & search code** — explore files, grep through the codebase, understand project structure - **Edit & write files** — create new files, modify existing ones, apply targeted edits - **Run terminal commands** — execute shell commands, run tests, start servers, install dependencies - **Search the web** — look up documentation, find solutions, research APIs - **Orchestrate work** — spin up parallel workstreams to tackle complex tasks efficiently I can perform a wide variety of software engineering tasks — from debugging and implementing features, to refactoring code, writing tests, reviewing architecture, and more. What would you like to work on? ## User How are u different than another agent ## Assistant Good question! A few things that set me apart: **Orchestration-first approach** — Most coding agents work sequentially, one step at a time. I manage multiple parallel workstreams simultaneously. When you ask me to understand a codebase, for example, I can explore the backend, frontend, CLI, and shared packages all at the same time, then synthesize the results. This makes me significantly faster on complex tasks. **Manager, not just executor** — I don't just run tools in a loop. I think about the best strategy for a task upfront — what workstreams are needed, what can run in parallel, what depends on what — and then orchestrate the execution. I'm more of a project manager that also does the work. **Context threading** — I can maintain separate workstreams with their own context and selectively share information between them. So if one thread deeply understands the auth system and another is working on a frontend feature that touches auth, I can pass just the relevant knowledge across without overwhelming either workstream. **Workspace-aware** — I work within your actual development environment. I read your real files, run your real commands, and understand your project's conventions, tooling, and structure as they actually are. That said, the fundamentals are similar to other AI coding tools — I read code, write code, run terminal commands, and search the web. The difference is mainly in *how* I coordinate and manage the work rather than the individual capabilities themselves. What can I help you build? ## User How do u store your sessions differently than say Claude Code or Opencode (see ~/.claude/ and ~/.opencode/ for examples) ## Assistant Great question — let me look at how they each store sessions locally.‍‍ ## Assistant ### Tool: orchestrate **Args:** ```json { "code": "\nconst [claude, opencode] = await Promise.all([\n system.thread(\"claude-storage\", \"Explore ~/.claude/ to understand how Claude Code stores its sessions.

Here's how they differ: ## Claude Code — Flat JSONL Files ``` ~/.claude/ ├── history.jsonl # Global index (one JSON line per session event) └── projects/ └── -Users-you-code-traces/ # Encoded project path └── .jsonl # One file per session ``` - Each session is a single `.jsonl` file — every message (user, assistant, tool use, tool result, thinking) is one JSON line - `history.jsonl` acts as a lightweight index with session IDs, timestamps, and preview text - Project paths are encoded in directory names (`/` → `-`) - Real-time updates: just append lines to the file - **Simple and flat** — everything for a session lives in one file ## OpenCode — Relational (SQLite or JSON) ``` ~/.local/share/opencode/ ├── opencode.db # SQLite with session/message/part tables └── storage/ # Legacy JSON format ├── session/{project_id}/{session_id}.json ├── message/{session_id}/{message_id}.json └── part/{message_id}/{part_id}.json ``` - **Relational structure**: sessions → messages → parts, each a separate record - SQLite version stores `data` columns as JSON blobs within proper SQL tables - Legacy version mirrors the same structure as individual JSON files on disk - Parts are typed (`text`, `reasoning`, `tool`, `file`, `snapshot`, `patch`, etc.) - Supports hierarchical sessions (subtasks via `parentID`) - **Normalized and structured** — closer to a database schema ## Me (Slate) — No Local Storage I don't persist sessions to your filesystem at all. My session lives entirely in memory during our conversation — my context is the message history between us, plus the orchestration traces from my worker threads. When this session ends, there's no `~/.slate/` directory left behind. That's actually one of the things this project solves — the Traces CLI reads from those agent-specific formats (via the adapters we just looked at), normalizes them into a common `events → messages + parts` model, and syncs them to the Traces platform so they become shareable regardless of which agent created them. ## User How many tools can you access at once, how many in parallel threads I mean? Do a demo, and max out ## Assistant Let's max it out!

Here's the full picture of what just ran: ## 20 Parallel Threads — Full Results ### Codebase Scale | Metric | Count | |--------|-------| | **Total TypeScript lines** | **111,401** | | **Test files** | 104 | | **Test lines** | 36,712 (33% of codebase) | | **React components** | 123 files, 13,150 lines | | **Frontend hooks** | 7 files, 647 lines | | **CLI adapters** | 12 files, 12,387 lines | | **CLI commands** | 19 impl files, 5,360 lines | | **TODO/FIXME comments** | Only 2! (very clean codebase) | ### Backend Stats | Metric | Count | |--------|-------| | **Database tables** | 14 | | **Database indexes** | 43 (40 regular + 2 search + 1 vector) | | **HTTP endpoints** | 63 across 16 route files | | **Convex functions** | 192 total | | — internalMutation | 105 | | — internalQuery | 65 | | — internalAction | 11 | | — public query | 10 | | — public mutation | 1 | ### Dependencies | Package | Count | |---------|-------| | Frontend | 53 | | CLI | 10 | | API | 9 | | Shared | 5 | | **Total** | **77** | ### Other Finds - **Environment variables**: 73 unique across the codebase - **className usages**: 1,032 in frontend components - **globals.css**: 1,148 lines - **Largest file**: `adapters.test.ts` at 5,557 lines - **Largest adapter**: Cursor at 2,178 lines - **20 recent commits** — latest work on CLI sync pipeline, scrub audits, Hermes adapter ### Thread Execution Summary The first batch fired **15 threads simultaneously** — 12 completed, 1 escalated (grep sandbox issue), and `Promise.all` short-circuited so 2 didn't finish. The second batch fired **5 more threads** to mop up the remaining work. That's **20 threads total**, with all results collected. The practical limit isn't fixed — it depends on how much work each thread does and system resources. 15 concurrent threads all running terminal commands and reading files worked fine. The main constraint is that `Promise.all` fails fast on any error, so for maximum resilience you'd use `Promise.allSettled` instead (which I'll do next time for a fan-out this wide).
