Phase 1 Plan 2: Channel/Agent/Routing Extraction Summary

Extracted message routing (240 lines), agent config (48 lines), and channel registration (102 lines) from daemon/index.ts into dedicated modules, reducing it from ~459 to 385 lines

Performance

• Duration: ~25 min (across two sessions)
• Started: 2026-02-10T04:08:12Z
• Completed: 2026-02-10T04:34:17Z
• Tasks: 3
• Files modified: 4 (3 created, 1 modified)

Accomplishments

• createMessageRouter (~240 lines) extracted to routing.ts — agent cache, sandbox wiring, audio transcription, command handling
• initAgents (~48 lines) extracted to agents.ts — AgentConfigRegistry, AgentRouter, SandboxManager with lifecycle shutdown
• registerChannels (~102 lines) extracted to channels.ts — all 8 adapter types (Telegram, Discord, Slack, WhatsApp, WebChat, CronScheduler, WebhookHandler, GmailWatcher)
• daemon/index.ts reduced from ~459 lines (post-Plan 01) to 385 lines; from 1087 baseline to 385 (65% reduction cumulative)
• All 1077 tests pass, zero regressions

Task Commits

Each task was committed atomically:

1. Task 1: Extract message routing into routing.ts — 08f5b6b (feat)
2. Task 2: Extract agent config into agents.ts — efceb38 (feat)
3. Task 3: Extract channel adapter registration into channels.ts — 35a0061 (feat)

Files Created/Modified

• src/daemon/routing.ts — Message router factory with agent cache, sandbox wiring, audio transcription, reset/compact/usage command handling (239 lines)
• src/daemon/agents.ts — Agent config registry loading, agent router creation, sandbox manager init with lifecycle shutdown (48 lines)
• src/daemon/channels.ts — All channel adapter registration: Telegram, Discord, Slack, WhatsApp, WebChat, CronScheduler, WebhookHandler, GmailWatcher (102 lines)
• src/daemon/index.ts — Reduced to infrastructure wiring only; imports and calls the three new modules (385 lines)

Decisions Made

• Used deps-interface factory pattern (ChannelsDeps, AgentsDeps) for explicit dependency injection rather than passing individual arguments — keeps call sites clean and extensible
• registerChannels returns cronScheduler (and webhookHandler, gmailWatcher) so startDaemon can still wire cron tools in Tier 1 tool registration
• Accepted pre-existing memory.ts and tools.ts extractions from Plan 01 session overflow — they were already integrated into index.ts and working

Deviations from Plan

Auto-fixed Issues

1. [Rule 3 - Blocking] Accepted pre-existing memory.ts and tools.ts extractions

• Found during: Task 1 (initial analysis)
• Issue: Previous Plan 01 session extracted src/daemon/memory.ts and src/daemon/tools.ts beyond its scope; both were already integrated into index.ts imports but untracked in git
• Fix: Accepted as-is — code was working and tested. These files were committed by the Plan 01 continuation agent (fb1199a for tools.ts, 00f8f74 for memory.ts`)
• Files affected: src/daemon/memory.ts, src/daemon/tools.ts (not our commits)
• Verification: All 1077 tests pass with these extractions in place

---

Total deviations: 1 auto-accepted (blocking — pre-existing code) Impact on plan: No scope creep. Pre-existing extractions were already working and simply acknowledged.

Issues Encountered

None — all three tasks executed cleanly.

User Setup Required

None — no external service configuration required.

Next Phase Readiness

• daemon/index.ts now contains only infrastructure wiring (385 lines): session store, hooks, skills, gateway, signal handlers, service startup, heartbeat monitor
• Plan 01-03 (remaining extractions: skills, gateway, lifecycle/infra) can proceed — depends on the output of Plans 01 and 02
• All daemon modules use consistent deps-interface factory pattern
