## Progress Assessment

### Completed Phases
- [x] Phase 1: Foundation - DONE (files: src/core/domain/*.ts)
- [x] Phase 2: Ink Rendering - DONE (tests: passing)

### Current Phase
- [ ] Phase 3: Agent Output Mode - IN PROGRESS
  - Created: src/render/agent/schemas.ts
  - Remaining: serializer.ts, streaming.ts

### Blocked/Deferred
- Phase 7: OpenTUI - BLOCKED (dependency: TanStack Router setup)

## Next Steps

### Immediate (This Iteration)
1. Complete `src/render/agent/serializer.ts`
2. Wire `--agent` flag to AgentOutputService
3. Add unit tests for CtlAgentOutput schema

### Dependencies
- Requires: CtlAgentOutput schema (DONE)
- Enables: Phase 4 (Project Discovery)

### Decision Points
- [ ] Choose streaming format: NDJSON vs SSE

## Current Intention

**Goal**: Complete Agent Output Mode (Phase 3)

**Approach**: Implement the serializer using Effect.Match for
discriminated union handling, output CtlAgentOutput JSON to stdout
when --agent flag detected.

**Success Criteria**:
- `ctl health --agent` outputs valid CtlAgentOutput JSON
- Schema validates with Effect.Schema.decodeUnknown
- Streaming updates emit progressive chunks

**Time Box**: 1 iteration cycle (~30 min focused work)
