- Deps-interface factory pattern (ChannelsDeps, AgentsDeps) for explicit dependency injection
- registerChannels returns cronScheduler so Tier 1 cron tools can still be wired in startDaemon
- Lifecycle wiring stays in the module that owns the resource (agents.ts owns sandbox shutdown)
- Grouped skills/MCP/pairing/gateway/startup into services.ts rather than multiple tiny modules
- getChannelAgents callback for late-binding channel agents into gateway token usage reporting
- Type-only imports in index.ts for values only referenced in DaemonContext type definition
### Technical Notes
- daemon/index.ts now 385 lines — models, memory, tools, routing, agents, channels all extracted
- Extracted modules: models.ts, memory.ts, tools.ts (Plan 01), routing.ts, agents.ts, channels.ts (Plan 02)
- Factory pattern established: initMemory(deps), initTools(deps), initAgents(deps), registerChannels(deps), createMessageRouter(deps), createModelRouter(config)
- Tier 1 agent tools remain in daemon/index.ts (depend on later-created objects)
- Remaining in daemon/index.ts: session store, hooks, skills, gateway, PairingManager, signal handlers, service startup, heartbeat monitor, Tailscale serve
- daemon/index.ts now 140 lines — thin composition root: imports → init calls → wire → return DaemonContext
- 8 extracted modules: models.ts (251), memory.ts (99), tools.ts (89), routing.ts (239), agents.ts (48), channels.ts (102), services.ts (269), lifecycle.ts (34)
- Factory pattern established for all modules: initX(deps) → result
- Tier 1 agent tools (session, agent list, message send, cron) remain in index.ts — they need deps from multiple init functions
- Web dashboard is vanilla JS SPA at src/gateway/ui/
- Config loader at src/config/loader.ts, schema at src/config/schema.ts (409 lines)

## Session Continuity
**Last session:** Plan 01-02 (extract routing/agents/channels) completed
**Stopped at:** Completed 01-02-PLAN.md
**Next action:** Execute Plan 01-03 (remaining extractions: skills, gateway, lifecycle/infra) or continue Phase 1
**Last session:** Plan 01-03 (composition root finalization) completed — Phase 1 done
**Stopped at:** Completed 01-03-PLAN.md (final plan in Phase 1)
**Next action:** Plan Phase 2 (Config Overlays) — run `/gsd-plan-phase` for Phase 2

# Phase 1 Plan 3: Daemon Composition Root Summary
**Extracted services/skills/MCP/gateway/lifecycle into services.ts (269 lines), achieving 140-line composition root — 87% reduction from 1087-line baseline**
## Performance
- **Duration:** ~8 min (across two sessions)
- **Started:** 2026-02-10T04:19:31Z
- **Completed:** 2026-02-10T04:27:00Z
- **Tasks:** 2
- **Files modified:** 2 (1 created, 1 modified)
## Accomplishments
- Extracted 6 functions into `src/daemon/services.ts`: initSkills(), initMcp(), loadSystemPrompt(), initPairingManager(), createGateway(), startServices()
- Reduced daemon/index.ts from 385 lines (post-Plan 02) to 140 lines — well under the 200-line target
- daemon/index.ts is now a pure composition root: imports → init calls → wire → return DaemonContext
- All 1077 tests pass, zero type errors, zero regressions
- Cumulative reduction: 1087 → 140 lines (87% reduction, 947 lines extracted)
## Task Commits
Each task was committed atomically:
1. **Task 1: Extract services/skills/gateway/MCP into services.ts, clean up index.ts**`701fcfc` (refactor)
2. **Task 2: Final validation** — No separate commit (validation-only task, all changes in Task 1)
## Files Created/Modified
- `src/daemon/services.ts` — Skills registry/installer, MCP server manager, system prompt assembly, pairing manager, gateway server creation, channel/gateway startup, Tailscale serve, heartbeat monitor, signal handlers (269 lines)
- `src/daemon/index.ts` — Thin composition root with organized imports, section dividers, DaemonContext return (140 lines)
## Decisions Made
- Grouped all remaining service initialization (skills, MCP, pairing, gateway, system prompt, lifecycle startup) into a single `services.ts` rather than multiple tiny modules — these all share config/lifecycle dependencies and are called sequentially
- Used `getChannelAgents()` callback pattern to handle late-binding of channel agents into gateway's token usage reporting — avoids circular dependency between channel registration and gateway creation
- Converted `ModelRouter`, `McpManager`, `SkillRegistry`, `SkillInstaller`, `GatewayServer` to type-only imports in index.ts since they're only referenced in the DaemonContext type definition (values come from factory functions in extracted modules)
## Deviations from Plan
None — plan executed exactly as written. daemon/index.ts was 385 lines as expected, extraction targets matched plan analysis, final line count (140) comfortably under the 200-line target.
## Issues Encountered
None.
## User Setup Required
None — no external service configuration required.
## Next Phase Readiness
- **Phase 1 complete:** daemon/index.ts is a 140-line composition root
- 8 daemon modules total: models.ts (251), memory.ts (99), tools.ts (89), routing.ts (239), agents.ts (48), channels.ts (102), services.ts (269), lifecycle.ts (34) — 1131 lines of extracted logic
- All modules use consistent factory pattern with typed deps/result interfaces
- Phase 2 (Config Overlays) can proceed — config loading changes are low-risk since daemon wiring is now modular
- Phase 3 (Live Ops Dashboard) can proceed — metrics hooks can be wired into individual modules rather than the monolithic god file
## Module Summary (Final State)
| Module | Lines | Responsibility |
|--------|-------|---------------|
| index.ts | 140 | Composition root — imports, wiring, DaemonContext |
| models.ts | 251 | Model client factory, GitHub mapping, auto-fallback, model router |
| services.ts | 269 | Skills, MCP, system prompt, pairing, gateway, service startup |
| routing.ts | 239 | Message router, agent cache, sandbox wiring, audio |
| channels.ts | 102 | All channel adapter registration (8 adapters) |
| memory.ts | 99 | Memory store, vector store, hybrid search, indexer |
| tools.ts | 89 | Tool registry, builtin tools, web search, process/browser managers |
| agents.ts | 48 | Agent config registry, agent router, sandbox manager |
| lifecycle.ts | 34 | Lifecycle state management |
| **Total** | **1271** | **Full daemon initialization** |
