Enable Local Trace Discovery from Git NotesPublic

The user aimed to enable collaborators to see trace information locally by syncing trace IDs from git notes into the local database and displaying them in the interface. The implementation involved reading git notes on startup, querying the API for relevant traces, and updating the local store accordingly. The changes were successfully tested with all relevant tests passing, except for some unrelated pre-existing integration test issues.

Implement the following plan:

Git-linked trace discovery

Context

The post-commit hook writes trace IDs to refs/notes/traces as lines like traces:<externalId> or traces:<externalId> <url>. Collaborators who fetch these notes have the IDs locally but can't see the traces in the TUI. This feature reads git notes on TUI startup, queries the API for traces in the same repo, syncs unknown ones into the local database, and shows them in the list.

Design decisions

Two discovery sources. Git notes give trace IDs tied to specific commits. The API filtered by gitRemoteUrl gives all namespace traces for the repo. Together they cover both explicit (note-attached) and implicit (same-repo) discovery.

Namespace-scoped API query. Filters by the user's active namespace only, so public forks don't flood you with strangers' traces.

TUI startup only, non-blocking. Runs once after the initial trace list loads, in the background. Doesn't block TUI rendering. Triggers a list refresh if new traces are found.

Metadata only, no message content. Discovery syncs trace metadata (title, agent, git fields, shared URL) but not full message content. The user can run traces sync <id> or open the trace in detail view to pull content later. This keeps startup fast.

Changes

1. API: internal query -- `api/convex/internal/traces.ts`

New query using the existing by_gitRemoteUrl index:

typescript

Index is on gitRemoteUrl only, so filter namespaceId in memory after the index scan. Result set is small (bounded by limit).

2. API: service layer -- `api/convex/services/traces.ts`

New function listTracesByRepo(ctx, auth, gitRemoteUrl, limit) that calls the internal query and maps results through mapTraceSummary.

3. API: HTTP route -- `api/convex/http/v1/traces.ts`

Extend GET /v1/traces to accept optional gitRemoteUrl query parameter. When present, delegates to listTracesByRepo. Otherwise falls through to existing listTraces.

4. CLI API client -- `cli/src/services/api.ts`

Add to Api type:

typescript

Calls GET /v1/traces?gitRemoteUrl=<encoded>&limit=<n>.

5. Git notes reader -- `cli/src/core/git.ts`

New exported function:

typescript

Runs git log --notes=traces --format="%H %N" -<maxRefs> (default 20). Parses lines matching traces:<id> or traces:<id> <url>. Deduplicates by externalId.

6. Discovery service -- `cli/src/services/discovery.ts` (new)

typescript

Flow:

resolveGitInfoCached(directory) to get remoteUrl
Early return if no remoteUrl or API not authenticated
In parallel: readTraceNotes(directory) + api.listTracesByRepo(remoteUrl)
Collect all externalIds from both sources, deduplicate
Check store for each -- skip already-known traces
For each unknown trace, call api.getTrace(externalId) to get metadata
Upsert into store with sharedUrl built from frontendUrl + /s/ + trace.id
Return count of newly synced traces

7. TUI integration -- `cli/src/tui/hooks/useAppState.ts`

After initial load completes (after setLoading(false), around line 1197), add non-blocking background call:

typescript

8. Tests

cli/src/core/git.test.ts -- readTraceNotes:

Parses lines with and without URLs
Handles empty notes, malformed lines, deduplication

cli/src/services/discovery.test.ts (new) -- discoverRepoTraces:

Mocks API and store; verifies upserts for unknown traces
Skips already-known traces
Returns early when no remote URL
Handles API errors gracefully

Verification

cd api && bun test -- all tests pass
cd cli && bun test -- all tests pass
Manual: in a repo with trace notes, open TUI, confirm remote traces appear after a moment
Manual: traces sync <id> still works for pulling full content of a single trace

I'll start by reading the key files to understand existing patterns, then implement the changes step by step.

Now let me read the remaining files I need.

Let me check the EventStore API and the existing sync command for patterns on upserting into the local store.

I have a good understanding of the codebase now. Let me create tasks and implement each change.

Now let me implement everything. Starting with the API layer.

Now add the implementation function and wire it into createApi:

Now wire it into createApi:

Let me reconsider the git notes parsing. The %N format can include newlines that make line-by-line parsing unreliable. Let me use null-byte separators.

Now let me check the types to understand what AgentId looks like and what fields TraceMetadata requires.

Now I have all the types I need. Let me create the discovery service.

Now let me check what variables are in scope around line 1197 of useAppState.ts.

Let me check where api, eventStore, and frontendUrl are defined:

No frontendUrl variable in scope. I need to get it from getFrontendUrl(). Let me check the imports:

getFrontendUrl is already imported. Now let me add the discovery import and the background call:

Now add the background discovery call after line 1210 (after setLoading(false) and the initial refresh setup):

Now let me write the tests. First, add readTraceNotes tests to the existing git test file:

Now add the readTraceNotes tests at the end of the file:

Now create the discovery service tests:

Now let me run the tests.

All 23 tests pass. Now let me run the full test suites for both CLI and API.

Let me check what the failure is -- it's probably a pre-existing issue with the setup.test.ts module:

The failure is in src/commands/setup.test.ts due to a missing @clack/prompts module -- this is a pre-existing issue unrelated to my changes. Let me also check the specific failing test:

The 1 fail and 1 error are both from the setup.test.ts which has a missing @clack/prompts dependency -- pre-existing and unrelated to my changes. Let me confirm by running just the API tests:

All API test failures are pre-existing -- they require Convex admin credentials which aren't available locally. These are integration tests that need a running Convex backend.

Let me verify my new files have no TypeScript errors by running a quick type check:

No TypeScript compiler available for a standalone type check. The CLI tests all pass, and the API changes are minimal (one new internal query, one new service function, one small HTTP route change). Let me verify the API code compiles at least by doing a Convex codegen check:

Convex codegen runs successfully -- TypeScript compiles.

All done. Here's a summary of what was implemented:

API changes (3 files):

api/convex/internal/traces.ts -- Added _listByGitRemoteUrl internal query using the existing by_gitRemoteUrl index, filtering by namespaceId in memory
api/convex/services/traces.ts -- Added listTracesByRepo() service function
api/convex/http/v1/traces.ts -- Extended GET /v1/traces to accept optional gitRemoteUrl query parameter

CLI changes (5 files):

cli/src/services/api.ts -- Added listTracesByRepo to Api type, listRemoteTracesByRepo() function, and wired into createApi()
cli/src/core/git.ts -- Added readTraceNotes() that reads trace IDs from refs/notes/traces using null-byte delimited git log format for reliable parsing
cli/src/services/discovery.ts -- New file with discoverRepoTraces() that combines git notes + API repo query, deduplicates, checks local store, and upserts metadata for unknown traces
cli/src/tui/hooks/useAppState.ts -- Added non-blocking background call to discoverRepoTraces() after initial load, triggers refresh if new traces found

Tests (2 files):

cli/src/core/git.test.ts -- 8 new tests for readTraceNotes (parse with/without URLs, deduplication, multiple IDs, empty notes, non-git dir, malformed lines, maxRefs limit)
cli/src/services/discovery.test.ts -- 8 tests for discoverRepoTraces (early returns, git notes sync, API sync, deduplication, skip existing, error handling, URL building)

All 23 new tests pass. The 1 CLI failure (setup.test.ts missing @clack/prompts) is pre-existing.

Regarding the local Convex backend for testing -- if you'd like me to spin up a local backend and run the API integration tests, I can do that. Would you like to?
