DevSpace currently loses the raw MCP tool-call trail once a request finishes, which makes it hard to inspect how a workspace reached a given review checkpoint. Persist workspace tool calls in SQLite at the centralized registration boundary, associate them with workspace/conversation metadata, and derive review-backed or timing-inferred activity groups without inventing a durable turn model.

Historical show_changes replays are intentionally excluded from the journal, and journal failures never affect the underlying tool call. Migration 9 adds the new durable activity table.

Prevent onError from replacing the tool outcome.

If onError throws, a start failure prevents operation from running. A finish failure can also replace a successful result.

Invoke onError through a non-throwing helper.

Keep activity grouping workspace-scoped.

Line 19 uses only conversationScopeId as the grouping key. Calls from different workspaces with the same conversation scope can merge into one activity group. The returned group has no workspace identifier to separate them later.

The sampled src/server.test.ts path filters listCalls by workspaceId, but that protects only that caller. Require an explicit workspaceId scope and reject mismatched calls, or partition by workspace before grouping. Add a test with identical conversation scopes in two workspaces.

As per coding guidelines, “Treat every operation as workspace-scoped and use workspaceId as the opaque handle returned by open_workspace.”

Greptile Summary

This change adds persistent workspace activity recording and grouping. Reproduced failures show that failed workspace opens leave inaccessible records, review history can split across pages, and unrelated unscoped conversations can merge into one activity timeline.

Confidence Score: 4/5

Safe to merge with non-blocking follow-up work recommended for activity retention, pagination, and attribution accuracy.

The reproduced issues affect activity-history correctness and cleanup rather than preventing normal workspace operations.

Files Needing Attention: src/workspace-activity-store.ts needs cleanup and group-aware pagination; src/workspace-activity.ts needs safer handling for calls without a conversation scope.

T-Rex T-Rex Logs

What T-Rex did

  • Compared persistence behavior before and after the change and confirmed identical storage of raw markers and 200,000-character payloads across revisions.
  • T-Rex produced proofs for multiple P2 findings and linked them to review comments.
  • Ran a workspace activity repro script and observed a failed open_workspace case with related null-id handling in the code path.
  • Verified that raw-row pagination splits groups and can omit earliest calls from a review when page size is limited.
  • Validated time-window merge behavior and missing openai/session handling, showing two unscoped conversations can render as a single inferred activity.

  1. General comment

    P2 Failed workspace opens create unreachable activity rows

    • Bug
      • When open_workspace fails before a workspace is created, activity capture writes an error row whose workspace_session_id is NULL. The public activity retrieval methods require a workspace ID and filter with equality to that ID, so this row cannot be returned. The nullable foreign key's cascade only applies when a referenced parent is deleted; the NULL row remains indefinitely under normal workspace cleanup.
    • Cause
      • WorkspaceActivityJournal records the call before open_workspace runs and on failure finishes it with no workspace ID (src/workspace-activity-journal.ts:31-42,59-66). startCall converts the absent ID to NULL (src/workspace-activity-store.ts:48-58), while listCalls, listCallSummaries, and getCall all filter by a supplied workspace ID (src/workspace-activity-store.ts:81-138). The schema permits NULL foreign keys (src/db/schema.ts:59-80).
    • Fix
      • Do not persist activity until a valid workspace ID is available, or provide a deliberate non-workspace activity retention/retrieval/cleanup path (for example, a bounded global activity log keyed by request/conversation) and explicitly purge such records.

  2. General comment

    P2 Raw-row pagination splits review activity groups

    • Bug
      • A four-call review persisted in SQLite is complete when retrieved unbounded, but with limit: 3 the first page groups only calls [2,3,4]; the remaining call [1] is returned on the next page without the review boundary and cannot be attached to the review group.
    • Cause
      • WorkspaceActivityStore.listCalls orders and limits database rows at src/workspace-activity-store.ts:93-94 before the separate grouping function receives them. The review marker is only on the final show_changes call, so an earlier overflow row has no review reference on the subsequent page.
    • Fix
      • Paginate complete activity groups rather than raw tool-call rows, or over-fetch and extend a raw page backward until the group boundary is included before grouping and deriving the next cursor.

  3. General comment

    P2 Unscoped MCP conversations are merged into one workspace activity group

    • Bug
      • groupWorkspaceToolCalls gives every call without conversationScopeId the same __unscoped__ conversation key. The executed repro sent two distinct two-call sequences for one workspace 30 seconds apart; all four unscoped calls were returned in the sole inferred group, whereas distinct supplied scopes returned two groups.
    • Cause
      • At src/workspace-activity.ts:19, nullish conversation scope IDs collapse to a single constant before grouping. Since groupConversationCalls only splits this bucket after an inactivity gap greater than two minutes (src/workspace-activity.ts:47-55, 73-82), different unscoped conversations within that window cannot be distinguished.
    • Fix
      • Do not use one shared fallback scope for absent session metadata. Preserve an origin-specific grouping discriminator (for example a request/conversation identifier when available), or make unscoped calls independent groups unless an explicit correlation signal is present.

P2 Clean up orphaned calls

When open_workspace fails before a workspace exists, activity capture writes the completed call with a NULL workspace ID. All activity lookups require a workspace ID, so this record can never be returned, and deleting workspaces cannot clean it up through the foreign-key cascade. Repeated failed opens therefore accumulate inaccessible records in the activity database. This is non-blocking, but it causes avoidable persistent storage growth. Avoid writing the call until a workspace is known, or add a bounded retrieval and cleanup path for workspace-less activity.

Artifacts

Evidence from the check

  • This authored script invokes the real journal and SQLite stores, then asserts insertion, retrieval, and cascade behavior; it is the exact executable proof used for the validation.

Command output from the check

  • This captured command output shows a NULL-workspace failed-open row, empty workspace-scoped retrieval results, and the row surviving an unrelated workspace deletion cascade; the activity record is unreachable and not cleaned up.

P2 Paginate complete groups

The query applies the page limit to individual tool-call rows before activity grouping. A review with more calls than the limit is returned as an incomplete review on the first page, while its earlier calls appear later without the review boundary. This is non-blocking, but it makes paginated activity history misleading and prevents callers from reliably reconstructing a complete review. Paginate complete activity groups, or extend each raw page through the relevant group boundary before returning it.

Artifacts

Evidence from the check

  • The authored TypeScript proof creates an oversized persisted review group, retrieves it unbounded and through raw-row pages, and asserts the observed grouping behavior.

Command output from the check

  • Executed `pnpm exec tsx trex-artifacts/review-group-pagination-proof.ts before` in `/home/user/repo` with exit code 0; all four persisted calls form one review group.

Command output from the check

  • Executed `pnpm exec tsx trex-artifacts/review-group-pagination-proof.ts after` in `/home/user/repo` with exit code 0; a limit of three omits call 1 from the first review group and the second page cannot identify it as part of that review.

P2 Separate unscoped conversations

If separate generic MCP conversations use the same workspace within two minutes without session metadata, the changed code assigns every call the shared __unscoped__ key. Their calls are then returned as one interleaved activity group instead of separate conversation histories. This is non-blocking, but it mixes tool history and attribution for users reviewing workspace activity. Preserve an origin-specific conversation identifier when available, or treat unscoped calls as independent unless an explicit correlation signal exists.

Artifacts

Evidence from the check

  • The executable TypeScript harness builds equivalent scoped and unscoped sequences for one workspace and asserts their observed grouping behavior; it is the source used for the captured runs.

Command output from the check

  • Running the authored harness with two distinct session scopes returned two inferred groups, establishing the non-merged control behavior.

Command output from the check

  • Running the same harness with both session scopes absent returned one inferred group containing call IDs 101, 202, 102, and 203, proving the merge.

Command output from the check

  • The repository's focused workspace activity tests were executed and passed two of two tests, confirming the grouping module runs successfully.

Command output from the check

  • The full test command ran 144 tests with 142 passing and one unrelated oauth-store migration expectation failure; the activity-path tests shown in the run passed.
