Phase 01 Plan 01: Extract Models, Memory, Tools Summary

Extracted model client factory (~250 lines), memory initialization (~100 lines), and tool registration (~90 lines) from daemon/index.ts into dedicated modules with factory function pattern

Performance

• Duration: 9 min
• Started: 2026-02-10T04:04:07Z
• Completed: 2026-02-10T04:13:22Z
• Tasks: 3
• Files modified: 4

Accomplishments

• Extracted 4 model client functions (createClientFromConfig, anthropicToGitHubModel, createAutoFallbackClient, createModelRouter) into src/daemon/models.ts with backward-compatible re-exports
• Extracted memory initialization (MemoryStore, VectorStore, HybridSearch, background indexer, memory tools) into src/daemon/memory.ts with initMemory() factory
• Extracted tool registration (ToolRegistry, allBuiltinTools, web search, ProcessManager, BrowserManager, ToolExecutor, ToolPolicy) into src/daemon/tools.ts with initTools() factory
• Reduced daemon/index.ts from 1088 lines to 458 lines (~58% reduction)
• All 1077 tests pass, zero regressions, clientFactory.test.ts unchanged

Task Commits

Each task was committed atomically:

1. Task 1: Extract model client logic into src/daemon/models.ts - 86cda91 (refactor)
2. Task 2: Extract memory initialization into src/daemon/memory.ts - 00f8f74 (refactor)
3. Task 3: Extract tool registration into src/daemon/tools.ts - fb1199a (refactor)

Files Created/Modified

• src/daemon/models.ts — Model client factory, GitHub model mapping, auto-fallback, model router creation (251 lines)
• src/daemon/memory.ts — Memory store, vector store, hybrid search, background indexer, memory tools registration (99 lines)
• src/daemon/tools.ts — Tool registry, builtin tools, web search, process tools, browser tools, tool executor, tool policy (89 lines)
• src/daemon/index.ts — Reduced to 458 lines, imports from extracted modules, re-exports models for backward compat

Decisions Made

• Used explicit deps/result interface pattern (MemoryDeps → MemoryResult, ToolsDeps → ToolsResult) for type-safe dependency injection
• Made initTools() synchronous since all tool setup is sync — only lifecycle shutdown handlers are async callbacks
• Kept Tier 1 agent tools (session, agents list, message send, cron) in daemon/index.ts because they depend on sessionManager, agentConfigRegistry, channelRegistry, and cronScheduler which are created later in startDaemon()
• Preserved backward-compatible re-exports from daemon/index.ts for model functions (clientFactory.test.ts imports from ./index.js)

Deviations from Plan

Auto-fixed Issues

1. [Rule 3 - Blocking] Fixed duplicate createMessageRouter conflict

• Found during: Task 2 (memory extraction)
• Issue: Pre-existing partial refactoring had created src/daemon/routing.ts with createMessageRouter extracted, and daemon/index.ts line 3 imported it, but the local function body (lines 67-289) was never removed — causing TS2440 duplicate identifier error
• Fix: Removed the duplicate local createMessageRouter function body from daemon/index.ts (routing.ts has the correct version)
• Files modified: src/daemon/index.ts
• Verification: pnpm typecheck passes
• Committed in: 00f8f74 (part of Task 2 commit)

2. [Rule 3 - Blocking] Adapted to pre-existing agents.ts extraction

• Found during: Task 3 (tool extraction)
• Issue: Pre-existing src/daemon/agents.ts with initAgents() already extracted agent config registry, agent router, and sandbox manager setup — index.ts already imported and used it
• Fix: No fix needed — acknowledged the pre-existing extraction and adjusted our import cleanup accordingly (AgentConfigRegistry, AgentRouter, SandboxManager already converted to type imports)
• Files modified: None additional
• Verification: Typecheck and all tests pass

---

Total deviations: 2 auto-fixed (2 blocking — pre-existing partial refactoring conflicts) Impact on plan: Pre-existing routing.ts and agents.ts extractions meant daemon/index.ts was already partially decomposed before we started. Our 3 extractions (models, memory, tools) combined with the pre-existing ones result in an even smaller index.ts (457 lines vs planned ~650-700).

Issues Encountered

None beyond the pre-existing partial refactoring noted in deviations.

User Setup Required

None - no external service configuration required.

Next Phase Readiness

• daemon/index.ts is now 458 lines with clear module boundaries
• Plan 01-02 (extract routing/channels) may already be partially complete due to pre-existing routing.ts extraction
• Plan 01-03 (extract remaining) can proceed independently
• All re-exports preserved for backward compatibility

Phase: 01-daemon-decomposition Completed: 2026-02-10

Self-Check: PASSED

• All 4 files verified present (models.ts, memory.ts, tools.ts, index.ts)
• All 3 task commits verified (86cda91, 00f8f74, fb1199a)
• Line counts match: models=251, memory=99, tools=89, index=458 (committed)
• Typecheck: clean
• Tests: 1077/1077 passed
