+# Tasks — Domain 2: Codebase Context & Code Intelligence
+
+## Phase 1: Migration (5 tasks)
+
+### 1. Route codecontext_client through boocontext MCP
+Update apps/server/src/services/codecontext_client.ts to support dual routing:
+- Check CODECONTEXT_MCP env var — when set, route tool calls through the boocontext MCP client instead of HTTP to the Go sidecar
+- Map old tool names to boocontext equivalents:
+  - get_codebase_overview → boocontext_overview
+  - get_file_analysis → boocontext_map
+  - get_symbol_info + get_symbol_details + search_symbols → boocontext_symbols
+  - get_semantic_neighborhoods → boocontext_map
+  - get_hot_files → boocontext_overview
+  - get_framework_analysis → boocontext_overview
+  - get_blast_radius → boocontext_impact
+  - get_routes → boocontext_overview
+  - get_middleware → boocontext_overview
+  - get_dependencies → boocontext_callgraph
+  - watch_changes → keep as-is (no boocontext equivalent)
+- Fall back to Go sidecar HTTP when boocontext unavailable
+- Preserve .codecontextignore handling, path validation, and truncation logic
+**Verification**: tsc --noEmit passes. Existing codecontext tests pass with both routing modes.
+
+### 2. Add get_code_health tool
+Create apps/server/src/services/tools/codecontext/get_code_health.ts
+- Wrap boocontext_health MCP tool
+- Schema: project path, optional file path for single-file health
+- Output: A-F grade per dimension (cohesion, coupling, complexity, documentation, duplication, unit size, test coverage) + project health summary + hotspots list + refactoring candidates
+- Register in tools/registry.ts ALL_TOOLS
+- Add to Architect, Refactorer, and Code Reviewer agent tool whitelists in data/AGENTS.md
+**Verification**: tsc --noEmit passes. Tool appears as get_code_health in /api/tools response.
+
+### 3. Add get_code_impact tool
+Create apps/server/src/services/tools/codecontext/get_code_impact.ts
+- Wrap boocontext_impact MCP tool
+- Schema: project path, symbol name, optional file path, depth (default 1)
+- Merges tree-sitter-analyzer symbol trace with codesight blast radius — single call
+- Register in ALL_TOOLS
+- Add to Architect and Planner agent whitelists
+**Verification**: tsc --noEmit passes. curl /api/tools shows get_code_impact.
+
+### 4. Add get_type_info tool
+Create apps/server/src/services/tools/codecontext/get_type_info.ts
+- Wrap boocontext_types MCP tool (backed by @nick-vi/type-inject-mcp)
+- Schema: project path, symbol name (regex), optional file path, kind filter (interface/type/class/function)
+- Output: type signatures, interface definitions, generic constraints, JSDoc, import paths
+- Register in ALL_TOOLS
+- Add to Code Reviewer, Debugger, Architect agent whitelists
+**Verification**: tsc --noEmit passes. Tool returns correct TypeScript types for known symbols.
+
+### 5. Add get_code_map tool
+Create apps/server/src/services/tools/codecontext/get_code_map.ts
+- Wrap boocontext_map MCP tool
+- Schema: project path, compress (boolean, default true)
+- DCP-compressed context map with filenames, sizes, import relationships
+- Register in ALL_TOOLS
+- Add to Recon agent whitelist
+**Verification**: tsc --noEmit passes. Map output is valid JSON with compress toggle working.
+
+## Phase 2: Hardening (2 tasks)
+
+### 6. Fix type-inject child path
+Update boocontext MCP environment:
+- Set BOOCONTEXT_TYPE_INJECT_NPX=@nick-vi/type-inject-mcp in docker-compose.yml or the boocontext MCP process env
+- Verify the hardcoded path /opt/forks/type-inject/packages/mcp/dist/index.js is no longer used
+**Verification**: boocontext_types tool works without /opt/forks/type-inject existing.
+
+### 7. Add graceful degradation
+Update boocontext child-server.ts or the tool wrappers:
+- On child MCP server failure (tree-sitter-analyzer or type-inject), retry once then fall back to codesight-only result
+- Return partial result with a warning message instead of hard error
+- Log the child failure for observability
+**Verification**: Unplug tree-sitter-analyzer → boocontext tools still return codesight-level results with a warning.
+
+## Phase 3: Wiki + Scanning (2 tasks)
+
+### 8. Add get_wiki_article tool
+Create apps/server/src/services/tools/codecontext/get_wiki_article.ts
+- Wraps codesight --wiki output via boocontext MCP
+- Schema: project path, article name (string)
+- Cache generated wiki articles to .codesight/ directory
+- First request generates the wiki; subsequent requests read cache
+- Register in ALL_TOOLS
+**Verification**: First call generates wiki; second call reads cache. Article content matches project structure.
+
+### 9. Enable DCP compression on get_codebase_overview
+Update get_codebase_overview.ts to pass compress: true for large projects
+- Adds configurable compress toggle (default: auto — compress when >50 files)
+- Matches boocontext_map's DCP pattern
+**Verification**: Large projects return compressed output under truncation limit.
+
+## Phase 4: Teardown (future, 1 task)
+
+### 10. Deprecate Go sidecar
+After all tools verified on boocontext MCP:
+- Mark codecontext Go sidecar as deprecated in docker-compose.yml comment
+- Add deprecation notice to codecontext/README.md
+- Remove from docker-compose.yml services block in a future batch
+- Remove codecontext/Dockerfile
+- Remove codecontext_client.ts Go HTTP path (keep MCP-only path)
