Phase 05: Subagent Codebase Analysis - 2 plans in 2 waves - Plan 05-01: Create gsd-entity-generator subagent (Wave 1) - Plan 05-02: Refactor analyze-codebase to use subagent (Wave 2) - Ready for execution Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>

Roadmap: v1.9.0 Codebase Intelligence System
Goal: Make GSD feel intelligent and automagical in how it navigates and understands both greenfield and brownfield projects.
Phases: 5 (4 complete)
Current Milestone: v1.9.0
Phase 1: Foundation & Learning ✓
Goal: Establish index schema and incremental learning via PostToolUse hook Status: Complete Plans: 2/2
Phase 2: Context Injection ✓
Goal: Inject codebase awareness into every session via SessionStart hook Status: Complete Plans: 2/2
Phase 3: Brownfield & Integration ✓
Goal: Deep analysis command for existing codebases, workflow integration Status: Complete Plans: 3/3
Phase 4: Semantic Intelligence & Scale ✓
Goal: Transform syntax-only indexing into semantic understanding with graph-based relationships Status: Complete Plans: 5/5
Plans:
- 04-01-PLAN.md — SQLite graph layer with sql.js (Wave 1)
- 04-02-PLAN.md — Graph-backed rich summary generation (Wave 2)
- 04-03-PLAN.md — Semantic entity generation via Claude API (Wave 2)
- 04-04-PLAN.md — CLI query interface for getDependents (Wave 3)
- 04-05-PLAN.md — Wire plan-phase.md to inject intel into planner (Wave 3)
Wave Structure:
- Wave 1: 04-01 (SQLite foundation)
- Wave 2: 04-02, 04-03 (parallel - both depend only on 04-01)
- Wave 3: 04-04, 04-05 (parallel - consumption layer)
Why this phase:
- Current system provides "2-3 ls commands worth of information" (Claude's own assessment)
- Missing: what files actually DO, who uses them, blast radius of changes
- Senior engineers at top companies need real intelligence, not file counts
Delivers:
- SQLite graph layer (sql.js - zero native deps) for relationship queries
- Entity-based semantic documentation (Claude writes understanding, not just syntax)
- Semantic
/gsd:analyze-codebasethat creates initial entities - Rich summary generation from accumulated semantic knowledge
- CLI query interface for "what uses this file?" queries
Requirements:
- INTEL-04: Entity files capture semantic understanding (purpose, what exports do)
- INTEL-05: Relationships queryable ("what uses this file?", "blast radius")
- INTEL-06:
/gsd:analyze-codebasecreates initial entity docs via Claude - INTEL-07: Summary reflects accumulated semantic knowledge
Success Criteria:
- Claude can answer "what uses src/lib/db.ts?" from SessionStart context
- Summary includes file purposes, not just file counts
- Transitive dependency queries work (blast radius)
- Works at scale (500+ file codebases)
Phase 5: Subagent Codebase Analysis
Goal: Prevent context exhaustion on large codebases by delegating analysis to subagents Depends on: Phase 4 Plans: 2 plans
Plans:
- 05-01-PLAN.md — Create gsd-entity-generator subagent (Wave 1)
- 05-02-PLAN.md — Refactor analyze-codebase to use subagent delegation (Wave 2)
Wave Structure:
- Wave 1: 05-01 (agent definition)
- Wave 2: 05-02 (command refactor + verification)
Why this phase:
- Current entity generation loads file contents in orchestrator context
- On large codebases (500+ files), orchestrator exhausts context during file selection and batching
- Subagent delegation gives fresh 200k context for entity generation
Delivers:
gsd-entity-generatorsubagent following gsd-codebase-mapper pattern- Refactored
/gsd:analyze-codebasethat spawns subagent instead of inline batching - Preserved orchestrator context for large codebase analysis
Requirements:
- INTEL-08: Entity generation delegated to subagent (not inline)
- INTEL-09: Subagent writes entities directly, returns statistics only
- INTEL-10: Orchestrator passes file paths, not file contents
Success Criteria:
- Entity generation works via subagent spawn
- Orchestrator context preserved (no file contents loaded)
- Entities correctly formatted and graph.db updated
- Works on 500+ file codebases without context exhaustion
