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-codebase produces useful codebase documents from any codebase
• Documents are focused (<100 lines each) and easy to update incrementally
• /gsd:new-project detects existing code and offers mapping
• /gsd:plan-phase loads 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: 14 of 14 (Researcher Agent) Plan: 1 of 3 in current phase Status: In progress Last activity: 2026-01-15 - Completed 14-01-PLAN.md

Progress: █████████████████████████░░ 31/33 plans (~94%)

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
13	Consolidated debugging expertise to 990 lines	Complete methodology with 59% reduction from source material
13	Thin orchestrator pattern for /gsd:debug	Orchestrator <200 lines, expertise in agent - reduces main context from ~2,400 to ~150
13	Deprecated reference files with redirect notices	No duplicate content between references and agent
14	4 explicit research modes	Ecosystem, feasibility, implementation, comparison cover all needs
14	Context7 > Official > WebSearch hierarchy	Prevents hallucination with authoritative sources first
14	902 lines from ~1,200 source (25% reduction)	Preserved all concepts while removing redundancy

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)
• Phase 12 added: Changelog & update awareness (remote changelog fetch, /gsd:whats-new, publish workflow integration)
• Phase 13 added: Dedicated debug agent (gsd-debugger with baked-in expertise, thin orchestrator pattern)
• Phase 14 added: Dedicated researcher agent (gsd-researcher with research methodology, tool strategy, output formats)
