Summary

Implement the following plan:

`traces sync` command

Context

traces 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.

Design decisions

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.

Changes

1. API client — `cli/src/services/api.ts`

Add two fetch methods and the reverse transform:

typescript

New types:

typescript

Reverse transform — buildEventFromMessage(msg: RemoteMessage, index: number): TraceEvent | null:

Look at first part type to determine event kind
text + role user -> UserMessageEvent
text + role assistant -> AgentTextEvent
thinking -> AgentThinkingEvent
tool_call -> ToolCallEvent
tool_result -> ToolResultEvent
error -> ErrorEvent
Fall back to textContent if no parts present

2. Sync command — `cli/src/commands/sync.ts` (new)

Follows the same runtime-injection pattern as share.ts and list.ts.

typescript

Flow:

Validate externalId is provided
Check API configured + authenticated
api.getTrace(externalId) — fetch metadata
api.getTraceMessages(externalId) — fetch messages with parts
Convert messages to TraceEvents
Build TraceMetadata from remote detail (agentId, title, timestamp, git fields, sharedUrl)
store.upsertTrace(metadata)
store.replaceEvents(externalId, events)
Output success

3. Options parser — `cli/src/commands/sync-options.ts` (new)

Positional arg for externalId, --json flag.

4. CLI entry point — `cli/src/index.ts`

Add sync command to the dispatch chain.

5. Tests — `cli/src/commands/sync.test.ts` (new)

Using runtime injection to mock API and store:

Missing externalId returns INVALID_ARGUMENTS error
Successful sync upserts trace and replaces events
JSON output format matches { ok, data: { traceId, messageCount, ... } }
API 404 returns TRACE_NOT_FOUND error
Unauthenticated returns AUTH_REQUIRED error

Verification

Share a trace first: traces share --trace-id <id> --json — note the externalId
traces sync <externalId> --json — confirm it stores and outputs correctly
traces list --json — confirm synced trace appears in the list

Now add the sync command dispatch. I'll add it after the list command:

Now add the sync command to the help text:

Used TaskUpdate

Now let me read a few more files to understand the types and EventStore patterns.

Used TaskUpdate

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:

typescript

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.

Readtypes.ts

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.

All 15 sync tests pass. Now let me run the full suite to check the other failures aren't mine.

My sync tests all pass (15 pass, 0 fail). There's 1 pre-existing failure and 1 pre-existing error that aren't related to my changes. Let me verify which ones they are.

Readevent-store.ts

The failing test is in setup.ts due to a missing @clack/prompts module, and the error is unrelated to my changes. These are pre-existing issues.

Used TaskUpdate

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

cli/src/services/api.ts - Added:

RemoteTraceDetail and RemoteMessage types for the API response shapes
getRemoteTrace() and getRemoteTraceMessages() fetch functions
buildEventFromMessage() reverse transform (inverse of buildMessagePayload) that converts API messages+parts back into CLI TraceEvents
getTrace() and getTraceMessages() methods on the Api type and createApi() factory

cli/src/commands/sync-options.ts (new) - Positional arg parser for externalId plus --json flag

cli/src/commands/sync.ts (new) - The sync command using the same runtime-injection pattern as share/list. Flow: validate args, check auth, fetch remote trace + messages via API, convert to events, upsert trace metadata and events into local EventStore

cli/src/commands/sync.test.ts (new) - 15 tests covering:

Missing externalId validation (JSON + human-readable)
API not configured / unauthenticated errors
Successful sync with upsert + event replacement verification
JSON and human-readable output formats
Correct event type conversion (text, thinking, tool_call, tool_result, error)
Fallback to textContent when no parts present
Default agentId to 'manual' when missing
API 404 mapped to TRACE_NOT_FOUND
Generic API errors mapped to SYNC_FAILED
Store cleanup on success and error

cli/src/index.ts - Added sync command dispatch and help text

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: https://github.com/market-dot-dev/traces/pull/253

Added the sync command section covering the new traces sync command, the reverse transform, and the 15 new tests.

lets also update https://github.com/market-dot-dev/traces/pull/246 desc

The traces sync command covers the "import by external ID" item and the "verify existing GET endpoint" item. Let me update those checkboxes.

Design doc for attaching trace IDs to git refs via git notes, so collaborators can browse the full agent context behind any PR.

Covers the git hook, GitHub App, CLI auto-import, trace export, and how these primitives enable further integrations (IDE, MCP, LSP, CI/CD).

## Work items

**Git hook (#248)**
- [x] Post-commit hook script -- queries for active traces, writes note, shares in background, pushes notes to remote
- [x] Shared URLs included in notes when available
- [x] Auto-push notes to remote after every commit
- [x] Auto-pull notes via global fetch refspec
- [x] Timestamp filtering -- only attaches traces active since previous commit

**CLI changes**
- [x] `traces active --dir <path>` command -- #249
- [x] Git metadata on traces (remoteUrl, branch, ref) stored at discovery time -- #253
- [x] `traces sync <externalId>` -- fetch a remote trace by external ID and store in local SQLite -- #253
- [ ] Replace direct SQLite queries in hook with `traces active` once released
- [ ] 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

**API changes**
- [x] Git metadata fields on trace create/upsert/detail endpoints -- #253
- [x] Existing `GET /v1/traces/:externalId` and `GET /v1/traces/:externalId/messages?includeParts=true` work for pulling traces (used by `traces sync`)
- [ ] `GET /v1/traces/:externalId/export?format=md` -- return trace as markdown

**GitHub App (separate project)**
- [ ] App that listens for PR webhooks, reads notes from repo, loads traces by external ID, posts comment

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

Used EnterPlanMode

Ran sub-agentExplore TUI startup and trace loading

Ran sub-agentExplore git hook and notes format

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.

Readlist-options.ts

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.

Ran sub-agentExplore gitRemoteUrl index and API

Good, the by_gitRemoteUrl index already exists but nothing queries it yet. Now let me read the key files I need for the plan.

Searched filespackages/shared/src/api/**/*.ts

Readtypes.gen.ts

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.
