Phase 5 Plan 01: Message Schema & Repository Summary

Messages table with sender/recipient pattern for agent-user communication, full CRUD repository with threading support

Performance

• Duration: 4 min
• Started: 2026-01-30T19:32:02Z
• Completed: 2026-01-30T19:35:38Z
• Tasks: 2
• Files modified: 7

Accomplishments

• Added messages table to schema with sender/recipient pattern (agent or user)
• Implemented MessageRepository port interface with comprehensive query methods
• Built DrizzleMessageRepository adapter with full CRUD operations
• Added message threading support via parentMessageId for response linking
• Created 23 tests covering all operations and edge cases

Task Commits

Each task was committed atomically:

1. Task 1: Add messages table to schema - f873a32 (feat)
2. Task 2: Create MessageRepository port and adapter - 19dc75c (feat)

Files Created/Modified

• src/db/schema.ts - Added messages table with relations
• src/db/repositories/message-repository.ts - Port interface with query methods
• src/db/repositories/drizzle/message.ts - Drizzle adapter implementation
• src/db/repositories/drizzle/message.test.ts - 23 comprehensive tests
• src/db/repositories/index.ts - Re-export MessageRepository types
• src/db/repositories/drizzle/index.ts - Re-export DrizzleMessageRepository
• src/db/repositories/drizzle/test-helpers.ts - Added messages table to test schema

Decisions Made

1. Sender/recipient participant pattern: Used senderType/senderId and recipientType/recipientId pairs to support both agent-to-user and user-to-agent messages
2. requiresResponse flag: Boolean distinguishes questions (needs reply) from notifications (informational)
3. Self-referential threading: parentMessageId links responses to original questions for conversation threading
4. SET NULL on delete: Foreign keys use SET NULL so messages persist even if sender/recipient agent is deleted

Deviations from Plan

None - plan executed exactly as written.

Issues Encountered

None

User Setup Required

None - no external service configuration required.

Next Phase Readiness

• Messages table ready for agent question persistence
• Repository supports all query patterns for pending messages and responses
• Ready for 05-02 (Task tRPC & CLI) and 05-05 (Message & Dispatch CLI)
