Phase 01.1 Plan 02: tRPC Foundation Summary

Type-safe tRPC router with health and status procedures, Zod validation, and comprehensive tests

Performance

  • Duration: 6 min
  • Started: 2026-01-30T12:52:38Z
  • Completed: 2026-01-30T12:58:19Z
  • Tasks: 2
  • Files modified: 3

Accomplishments

  • Added health procedure returning { status, uptime, processCount }
  • Added status procedure returning { server: {startedAt, uptime, pid}, processes: [] }
  • Zod schemas for runtime output validation
  • AppRouter type exported for client type-safety
  • 16 tests covering procedures and schema validation

Task Commits

Each task was committed atomically:

  1. Task 1: Install tRPC dependencies and create router foundation - 437e76e (done in prior session as part of Plan 01.1-01)
  2. Task 2: Define procedures matching HTTP endpoints with tests - 551e516 (feat)

Plan metadata: (this commit)

Note: Task 1 was completed as part of Plan 01.1-01 execution. This plan focused on Task 2.

Files Created/Modified

  • src/trpc/router.ts - Added appRouter with health/status procedures, Zod schemas
  • src/trpc/index.ts - Export AppRouter type and schemas
  • src/trpc/router.test.ts - 16 tests for procedures and validation

Decisions Made

  1. Zod for output validation - Ensures runtime type safety; procedures validate their outputs match declared schemas
  2. Match HTTP endpoint shapes - health and status procedures return same data as existing /health and /status HTTP endpoints for consistency

Deviations from Plan

Auto-handled

1. [Rule 3 - Blocking] Task 1 already completed

  • Found during: Task 1 verification
  • Issue: tRPC foundation files already existed from Plan 01.1-01 execution
  • Resolution: Verified existing files met Task 1 requirements, proceeded to Task 2
  • Impact: None - reduced work, no code changes needed for Task 1

Issues Encountered

None - plan executed as expected.

User Setup Required

None - no external service configuration required.

Next Phase Readiness

  • tRPC router ready for HTTP adapter integration (Plan 01.1-06)
  • Type-safe contract established for CLI-server communication
  • Procedures match existing HTTP endpoint contracts
