Agent sessions need durable per-invocation history for coordination, but that history should remain an internal implementation detail. This adds a local_agent_turns migration and store operations that begin and finish a prompt, response, or error atomically with the parent agent record.

The manager now records start and continuation work through that lifecycle, and restart reconciliation closes any turn left running by a dead daemon. No turn ID, prompt, or prior output is added to the CLI presentation contract. Store, manager, migration, and restart behavior are covered by focused tests, and the full test suite passes.

Summary by CodeRabbit

  • New Features

    • Added per-turn tracking for local agent runs, including prompts, responses, statuses, timestamps, and provider errors.
    • Added access to turn history and the latest turn for each local agent.
    • Turn results now clearly distinguish running, completed, failed, and stopped states.
    • Prevented overlapping turns for the same local agent.
  • Bug Fixes

    • Interrupted runs are now automatically marked as failed with a daemon-unavailable error, preventing stale running states.
    • Turn outcomes and errors are preserved consistently across restarts.

📝 Walkthrough

Walkthrough

The PR adds workspace recovery migration 7 and local-agent turns migration 8. LocalAgentStore manages turn lifecycles and reconciliation. LocalAgentManager records completed and failed outcomes by turn ID. Tests cover lifecycle, persistence, interruptions, and provider failures.

Changes

Local agent turn tracking

Layer / File(s) Summary
Turn database schema
src/db/migrations.ts, src/oauth-store.test.ts
Migration 7 adds recovery_kind to existing workspace sessions. Migration 8 creates local_agent_turns with indexes and cascade deletion. Migration tests include both migrations.
Turn lifecycle and persistence
src/local-agent-store.ts, src/local-agent-store.test.ts
LocalAgentStore adds turn types and lifecycle methods. Transactions create and finish turns, query turn history, validate statuses, and mark active turns as DAEMON_UNAVAILABLE during reconciliation. Tests cover completed and failed turns, shared store state, and upgraded legacy agents.
Manager execution integration
src/local-agent-manager.ts, src/local-agent-manager.test.ts
LocalAgentManager starts turns and passes turn IDs through success and error paths. Tests verify completed prompts, interrupted turns, and provider failures.

Estimated code review effort: 3 (Moderate) | ~25 minutes

Merge Risk: 🟠 High · up to a9796

The new turn history schema prevents running turns from being created, so agent sessions cannot start successfully. The migration constraint must be corrected before merge.

Greptile Summary

Persists every local-agent prompt and terminal result in SQLite while retaining the existing session-level status and latest-result view.

  • Adds the version 7 local_agent_turns migration with session ownership and lookup indexes.
  • Adds transactional APIs to begin, finish, reconcile, and retrieve persisted turns.
  • Integrates turn lifecycle persistence into agent start, continuation, success, failure, and restart recovery flows.
  • Expands store and manager tests to cover completed, failed, reconciled, shared, and upgraded turn state.

Confidence Score: 5/5

The PR appears safe to merge, with no concrete blocking or independently actionable non-blocking defects identified.

Turn creation and completion are transactionally coordinated with session state, existing databases receive an ordered migration, and restart reconciliation now consistently resolves both active sessions and their persisted turns.

Important Files Changed

Filename Overview
src/db/migrations.ts Adds an ordered migration for durable, cascading local-agent turn records and supporting indexes.
src/local-agent-store.ts Adds transactional turn lifecycle persistence, retrieval methods, row conversion, and restart reconciliation.
src/local-agent-manager.ts Routes each agent execution through a persisted turn and finalizes that turn on every success and error path.
src/local-agent-store.test.ts Covers completed and failed history, visibility across store handles, and use after legacy migration.
src/local-agent-manager.test.ts Verifies manager-driven completion, continuation, failure, and restart reconciliation update turn history.
src/oauth-store.test.ts Updates the expected migration ledger to include the new turn-history migration.
