Context isolation is the primary goal, not parallelization. Even sequential plans spawn separate subagents for fresh 200k context. Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>

Project State
Project Summary
Building: Brownfield support for GSD - /gsd:map-codebase workflow that analyzes existing codebases using parallel Explore agents, producing structured .planning/codebase/ documents.
Core requirements:
/gsd:map-codebaseproduces useful codebase documents from any codebase- Documents are focused (<100 lines each) and easy to update incrementally
/gsd:new-projectdetects existing code and offers mapping/gsd:plan-phaseloads relevant codebase context automatically- Codebase map updates after plan execution
Constraints:
- Explore agents required for initial mapping
- Each codebase map file must stay under ~100 lines
- Only load relevant codebase sections into phase planning
- Follow existing GSD command/workflow/template patterns
Current Position
Phase: 99 of 99 (Test Parallel - THROWAWAY) Plan: 3 of 3 in current phase Status: Phase complete (via parallel execution) Last activity: 2026-01-12 - Completed Phase 99 via /gsd:execute-phase
Progress: Test phase complete (throwaway - not counted in main milestone)
Performance Metrics
Velocity:
- Total plans completed: 23
- Average duration: 3.7 min
- Total execution time: 85 min
By Phase:
| Phase | Plans | Total | Avg/Plan |
|---|---|---|---|
| 1 | 3 | 9 min | 3 min |
| 2 | 2 | 5 min | 2.5 min |
| 3 | 1 | 2 min | 2 min |
| 4 | 2 | 7 min | 3.5 min |
| 5 | 2 | 5 min | 2.5 min |
| 6 | 2 | 4 min | 2 min |
| 7 | 1 | 4 min | 4 min |
| 8 | 1 | 1 min | 1 min |
| 9 | 1 | 3 min | 3 min |
| 10 | 4 | 33 min | 8.3 min |
| 11 | 4 | 12 min | 3 min |
| 99 | 3 | 1 min | <1 min (parallel) |
Recent Trend:
- Last 5 plans: 11-02 (2m), 11-03 (3m), 11-04 (3m), 99-01/02/03 (<1m parallel)
- Trend: Parallel execution dramatically faster
Updated after each plan completion
Accumulated Context
Decisions Made
| Phase | Decision | Rationale |
|---|---|---|
| 0 | Folder with focused files | Easier to update incrementally than monolithic file |
| 0 | Update after plan execution | Fits existing STATE.md update pattern |
| 0 | Parallel Explore agents | Thoroughness for initial mapping |
| 0 | Selective context loading | Avoid loading irrelevant sections |
| 6 | Frontmatter with dependency graph | Enable automatic context assembly via transitive closure |
| 6 | Intelligent summary selection | Scan frontmatter, build graph, auto-select relevant phases |
| 8 | Active milestone details in ROADMAP.md | Single source of truth during development, archive only on completion |
| 9 | Phase-scoped UAT issues | Keep UAT findings tied to specific plan, not global ISSUES.md |
| 10 | git mv preserves history | Rename workflow while keeping git history intact |
| 10 | execute-plan = single, execute-phase = parallel | Clear naming for single-plan vs multi-plan execution |
| 10 | Agent-history v1.2 schema | Extended for parallel tracking, dependencies, resume support |
| 11 | Frontmatter parallelization markers | parallelizable, depends_on, files_exclusive in plan template |
| 11 | Vertical slices over workflow stages | Maximize independence when parallelization enabled |
| 11 | SUMMARY references only when needed | Avoid reflexive sequential chains |

Roadmap Evolution
- Phase 4 added: Plan-phase optimizations (~37% context reduction target)
- Phase 5 added: TDD instructions for appropriate test-driven development
- Phase 6 added: Frontmatter and related system upgrade
- Phase 7 added: Backfill existing summaries with frontmatter
- Phase 8 added: Improve roadmap system
- Phase 9 added: Integrate verify-work (community contribution from OracleGreyBeard)
- Phase 10 added: Parallel phase execution (rename workflow, create /gsd:execute-phase with parallelization)
- Phase 11 added: Parallel-aware planning (update plan-phase.md to create parallelizable plans when enabled)
