We're inside cli/ already. The git status showed hooks/ as the untracked path.

Let me check if the hook fired on that commit.

The hook fired and attached 16 trace IDs to the commit. Committed as f57dd12.

Yeah, that's every trace ever recorded in this directory. The query has no time filter — it returns all traces whose directory matches the repo root, including old finished ones.

Should I scope it to only recent traces (e.g., last 24 hours, or since the previous commit)?

Now let me check the DB schema to understand the traces table columns, particularly the directory and id columns.

Let me look at the actual git-ai repo.

git-ai takes a very different approach. It runs a pre-commit checkpoint that snapshots the working tree, maintains a per-commit working log tracking which files each agent touched, then at post-commit computes line-level attributions from the diff. It doesn't match sessions by directory at all -- it tracks edits continuously.

For our case (just attaching trace IDs), a simpler heuristic works: only include traces whose last activity timestamp is after the previous commit. That way each commit only picks up traces that were active during the work that produced it.

Now update the tests to cover the timestamp filtering.

All 9 tests pass. Now reinstall the updated hook and let me clean up.

The hook now filters by timestamp: it only includes traces whose last activity (timestamp column, in ms) is at or after the previous commit's author date. First commits in a repo still include all matching traces. Want me to commit this?

Down from 16 to 1. That's the current active trace for this session.

The id in the local DB is a UUID (a8f01d3c-295f-4043-ae2a-417299a74100), but the URL you shared uses a different slug format (jn75ck1sekp0z805jnf3fvqsjs81qs1b). Let me check how those relate.

No shared_url stored for this trace. The URL slug (jn75ck1sekp0z805jnf3fvqsjs81qs1b) is a separate server-side identifier, not the same as the local id (which is a UUID). The id column is what gets sent to the API as externalId, and the slug in the /s/ URL is something else -- probably the Convex document ID or a share token.

So the note currently says traces:a8f01d3c-295f-4043-ae2a-417299a74100 which is the externalId, and the API has GET /v1/traces/:externalId to look it up. The /s/ URL uses a different identifier. Both should resolve to the same trace but through different routes.

Does that match your understanding, or should the note contain the share slug instead?

Now update the tests.

All 12 tests pass. Reinstalling the hook.

Now about triggering the share from the hook -- let me check how sharing works in the CLI.

The sharing requires the full CLI runtime (Bun, adapters, API auth). That's too heavy for a shell hook -- the hook needs to stay fast and never block commits.

But looking at the plan, the intended approach was traces sync <externalId> & running in the background. Does the CLI have a sync or share subcommand?

There's a traces share --cwd . --json command that does exactly this. The hook can shell out to the traces CLI in the background to share each unshared trace. Let me check how the binary is invoked.

Good. The traces table in SQLite has id TEXT PRIMARY KEY and directory TEXT. The id column is what the CLI uses as the trace identifier, which maps to externalId in the API. Now let me check the existing git integration doc and the current branch state.

That works. Now I can add a background share step to the hook. For each trace without a shared_url, call traces share --trace-id <id> --json in the background. Then after sharing, re-read the shared URLs and include them in the note.

Actually, the simpler approach: share first, then build the note with the URLs that come back. But sharing is slow (network call) and shouldn't block the commit. Better approach: write the note immediately (fast), then share in the background and update the note with URLs after.

Let me update the hook.

All passing. Let me reinstall and test it live.

Updated hook now:

1. Writes the note immediately with whatever URLs are already in the DB (never blocks)
2. Kicks off a background subshell that calls traces share --trace-id <id> --json for each unshared trace
3. Rewrites the note with the returned URLs once sharing completes

The background share only runs if the traces CLI is on $PATH. If it's not installed or sharing fails, the note still has the trace IDs -- just without URLs.

Want me to commit?

The background share worked. The note now includes both the trace ID and the shared URL.

PR opened: https://github.com/market-dot-dev/traces/pull/248

Done.

The notes aren't on the remote -- git notes only writes locally by default. I need to push them.

Pushed. Now Tarun can run:

git fetch origin refs/notes/traces:refs/notes/tracesgit notes --ref=traces show HEAD

We should also add the push refspec to the hook so notes get pushed automatically in future. Right now the hook writes notes locally but doesn't push them -- that's a separate step. Want me to add auto-push of notes to the hook, or keep it manual for now?

Good call. Let me also add a post-merge hook (runs after git pull) to fetch notes, and update the post-commit hook to also fetch before writing.

Actually, the cleanest approach: configure the fetch/push refspecs globally during install so notes travel automatically with every git fetch and git push. That way we don't need a separate hook for pulling.

Now let me also add a fetch of notes at the start of the hook, so we don't clobber notes from collaborators when we --force write.

Actually, the fetch refspec approach is better than fetching in the hook. Fetching notes inside a post-commit hook would add latency to every commit. Instead, configuring the refspec means notes come down automatically with every git fetch / git pull that the user already does.

Let me set up the global refspecs now and update the install instructions.

Now let me run the tests and install the updated hook.

To answer your question about appending notes -- yes, git notes append exists. It adds to an existing note instead of replacing it. That would let multiple collaborators each add their trace IDs to the same commit without overwriting each other's notes.

Right now the hook uses git notes add (fails if a note already exists) for the initial write and git notes add --force (overwrites) for the background rewrite with URLs. If two people commit to the same ref, they'd each have their own commit so there's no collision. But if we ever need to add notes to someone else's commit, append would be the right call.

Want me to switch to append mode, or is the current behavior fine for now?

With append, the background rewrite gets trickier -- we can't just replace the whole note since there might be lines from other collaborators. The background step needs to read the existing note, update just its own lines, and write back. Let me rethink this.

Simplest correct approach: always append. For the background URL update, remove the bare ID line and append the line with the URL.

Now update the tests -- append means the note accumulates lines across calls, so the test for "shared_url included" needs to account for that.

Let me first check how the CLI handles the DB path and TRACES_EVENTSTORE env var.

All pass. Install and commit.

The background subshell is racing with this push. Let me push the commit explicitly.

Notes already pushed by the background process. Both the branch and notes are up to date on the remote. Tarun can now just git pull and the notes will come down automatically (once he adds the fetch refspec), or manually with:

git fetch origin refs/notes/traces:refs/notes/traces

Now I have all the context I need. Let me create the branch and the hook script. I noticed a bug in the plan's script ([ -z "$IDS" ] || exit 0 should be && exit 0) — I'll fix that.

Notes came down with the clone automatically -- no extra fetch needed. The +refs/notes/traces:refs/notes/traces refspec in the global git config means any clone/fetch pulls notes along with everything else.

Working end to end. Fresh clone, notes visible on every commit with trace URLs inline. The earlier commit (ceb270e) has just the ID since that was before background sharing was added.

Here's where we are against the PR 246 work items:

Git hook -- all done

• Post-commit hook script -- queries SQLite directly (skipped the traces active command, went straight to the DB), writes note, kicks off background share
• Auto-push notes to remote after every commit
• Auto-pull notes via global fetch refspec (no separate hook needed)
• Installer instructions in the script header

CLI changes

• traces active --dir <path> -- we bypassed this by querying SQLite directly in the hook, which is simpler and has no CLI dependency for the core flow. Still useful as a standalone command but not blocking.
• traces sync <externalId> -- we used the existing traces share --trace-id <id> instead, which does the same thing (upload to API). A dedicated sync command could be lighter weight.
• traces import <file|url> -- not started
• Git-linked trace discovery on startup -- not started

API changes -- not started

• Export endpoints
• Cross-user trace access

GitHub App -- not started (separate project)

So the demo goal ("get trace IDs written to git notes on commit") is fully working, plus we went beyond it with shared URLs, background upload, and auto-push/pull of notes. The remaining items are about building on top of that foundation.

Updated. The git hook section now reflects what we actually built, and the CLI items we bypassed are marked as done with a note on the approach we took instead.

Good point. The hook should be a thin wrapper that shells out to the CLI, not embed SQL queries that'll drift as the schema evolves.

Updated. The active and sync CLI commands are back as open items, with a note to replace the direct SQLite queries in the hook once they exist.

Let me look at how the existing CLI commands are structured and registered.

Let me look at list.ts since active will be similar -- both query the local DB and output traces.

Now let me look at the list test to understand the test pattern.

Good, I have the full pattern. Now let me build the active command. It needs to:

1. Scan for traces (like list)
2. Filter by --dir (directory match)
3. Filter by --since (timestamp, for the hook's "since previous commit" logic)
4. Output trace IDs (and shared URLs if available) in a format the hook can consume

Now register it in the CLI entry point.

Now add it to the help text.

Now write the tests.

Now let me also test the option parser.

Now run the full test suite.

622 pass (+14 from our new tests), same 1 pre-existing failure (missing @clack/prompts). Let me quickly test it end to end.

That's the pre-existing setup module issue. Let me use the installed binary instead.

Right, the installed binary is the released version. The command works in tests; it'll be available once this gets released. Let me commit.

PR opened: https://github.com/market-dot-dev/traces/pull/249

Once this lands and gets released, the hook can replace its SQLite queries with traces active --dir "$REPO_ROOT" --since "$SINCE" --json.

The help text in index.ts is already updated. Beyond that, the git integration doc seems like the right place since it describes the hook and this command exists to support it.

The git integration doc lives on the git-integration-doc branch and hasn't been merged to main yet. I'd add it to that doc -- it already describes the hook and the traces active / traces sync commands as planned pieces. We can update it to reflect what actually got built.

Want me to switch to that branch and update the doc, or would you rather wait until the active command PR merges first?

Now update the ordering section to reflect what's done.

Also update the git-ai reference URL.

Pushed. The doc on PR #246 now reflects what we actually built -- the hook interface, traces active command, note format with shared URLs, append behavior, installation steps, and verification commands.

Right now, nothing. The hook uses traces share --trace-id <id> to upload, and that's all sync was meant to do -- push trace content to the API.

The original plan imagined sync as a lighter-weight upload (just push events, no visibility change) versus share which also sets the trace to public/direct visibility and returns a shareable URL. In practice, share already does both -- it uploads and returns a URL. There's no reason to build a separate sync command when share handles it.

I'd drop sync from the plan entirely and just use share.

Yes, traces share --trace-id <id> --visibility private works. It accepts public, direct, or private.

So the hook could use --visibility private if you want traces uploaded but not publicly browsable by default. Right now it calls share without --visibility, which defaults to public for personal namespaces and private for org namespaces.

Good. So we can scratch sync from the plan -- share covers it. I'll update the PR description.

Done.

The directory column works for local matching, but it breaks across machines -- my /Users/andrew/code/traces/traces is someone else's /Users/tarun/code/traces. A git remote URL would be stable across clones.

Let me look at what we'd need to change.

Now let me write a test for this. I'll create a shell-based test that sets up a temp git repo, populates a test SQLite database, runs the hook, and verifies the git notes.

Now let me also check the TraceMetadata type.

Let me also check what the API already sends for projectPath -- it might already have a concept of repo URL.

Here's what I'd suggest for the schema. Three new columns:

• git_remote_url -- the normalized remote URL (e.g. github.com/market-dot-dev/traces). Stable across machines, lets you find all traces for a repo regardless of where it's checked out.
• git_branch -- the branch name at the time the trace was recorded. Useful for filtering ("show me traces from the feat/auth branch").
• git_commit -- the HEAD commit SHA when the trace started. Gives you a precise point in history to anchor the trace to.

The directory column stays -- it's still useful for local matching and the hook needs it. These new fields supplement it with git-aware identity.

The question is where the data comes from. The adapters already know the directory, so we'd resolve git info from there at scan time: run git -C <directory> config --get remote.origin.url, git -C <directory> symbolic-ref --short HEAD, and git -C <directory> rev-parse HEAD. This keeps it out of the adapters themselves and works for all agents.

Should I go ahead and build this? It'd be a migration adding the columns, populating them during trace discovery, and exposing them through the active command.

I need to continue planning the schema extension for git metadata. Let me explore the relevant code areas.

Good call — git_ref is more general and covers tags, detached HEADs, etc. Let me update the plan.

Let me read a couple of key files to verify details before finalizing.

Let me check the API sync and Convex schema to understand how to flow git data to the server.

Let me check if the shared types are generated or hand-written, and look at the OpenAPI spec.

The types are auto-generated. Let me find the OpenAPI spec that generates them.

Let me check how types are regenerated from the spec.

Let me debug the hook.

Now let me also check the Convex validators and the internal sync mutation args to understand the exact arg types needed.

Good. Now I have the full picture across all layers. Let me also check the Convex schema more carefully for the traces table.

Now I have everything. Let me write the plan.

The issue is on macOS: mktemp -d returns /var/folders/... but git rev-parse --show-toplevel resolves the symlink to /private/var/folders/.... The directory stored in the DB doesn't match the resolved path.

I need to handle this in both the hook (resolve the repo root to a real path) and the test (store the resolved path in the DB). Let me fix the hook first.

Let me check how the CLI stores the directory value in traces.

The issue is macOS symlinks: mktemp -d returns /var/folders/... but git rev-parse --show-toplevel resolves to /private/var/folders/.... In practice this only affects temp directories (real repos under /Users don't have this issue), but let me make the hook resolve symlinks to be safe.

Now fix the test to also resolve the temp dir path when inserting into the DB.

I need to resolve the temp dir paths in the test so they match what pwd -P returns inside the hook.

All 6 tests pass. Let me verify the final state of the hook script.

Now let me also run the existing project tests to make sure nothing is broken.

Let me check if the failing test is pre-existing (not caused by our changes).

Pre-existing failures (missing @clack/prompts module and a server verification issue), not related to our changes.

Here's a summary of what was done:

New files:

• cli/hooks/post-commit — Shell script that queries ~/.traces/traces.db for traces whose directory matches the current repo root, then writes their IDs as git notes under refs/notes/traces on HEAD. Respects TRACES_EVENTSTORE env var (absolute or relative path). Fails silently if sqlite3 is missing, no DB exists, or no traces match.

• cli/hooks/post-commit.test.sh — Tests covering: writing trace IDs as notes, no-match produces no note, missing DB exits cleanly, relative TRACES_EVENTSTORE resolution, and no-match directory exits cleanly. All 6 pass.

Bug fix from the plan: The plan had [ -z "$IDS" ] || exit 0 which would exit when IDs are found. Fixed to [ -n "$IDS" ] || exit 0.

Additional fix: Added symlink resolution via cd ... && pwd -P so the hook works correctly on macOS where /var is symlinked to /private/var.

Want me to commit this?

Installed. The hook is at ~/.traces/hooks/post-commit and core.hooksPath is set globally. Next commit in any repo will trigger it.
