Produces comprehensive research files (SUMMARY, STACK, FEATURES, ARCHITECTURE, PITFALLS) in `.planning/research/`. **Key Patterns**: - Three research modes: Ecosystem, Feasibility, Comparison - Tool hierarchy: Context7 → Official docs → WebSearch → Verification - Confidence levels (HIGH/MEDIUM/LOW) with source attribution - Treats training data as hypothesis requiring verification **Artifacts**: - Creates: `.planning/research/{SUMMARY,STACK,FEATURES,ARCHITECTURE,PITFALLS}.md` - Reads: PROJECT.md, Context7, WebFetch, WebSearch **Workflow Stage**: Discovery (pre-Planning) **Local Candidates**: | Local File | Similarity Reason | Priority | |------------|-------------------|----------| | `plugins/plugin-creator/skills/feature-discovery/SKILL.md` | Autonomous research producing artifacts, identifies gaps | **High** | | `.claude/skills/research-and-compare/SKILL.md` | Verification protocol, confidence levels | **High** | | `plugins/python3-development/agents/feature-researcher.md` | Researches before implementation, surfaces questions | Medium | --- ### Source 3: gsd-research-synthesizer.md **Purpose**: Synthesizes outputs from 4 parallel researcher agents into unified SUMMARY.md. Convergence point after parallel discovery research. **Key Patterns**: - Multi-source synthesis (reads 4 research files) - Executive summary creation - Pattern identification across domains - Roadmap implications derivation - Atomic commit of all research outputs **Artifacts**: - Creates: `.planning/research/SUMMARY.md` - Reads: `.planning/research/{STACK,FEATURES,ARCHITECTURE,PITFALLS}.md` **Workflow Stage**: Planning/Synthesis **Local Candidates**: | Local File | Similarity Reason | Priority | |------------|-------------------|----------| | `plugins/python3-development/agents/codebase-analyzer.md` | Writes analysis docs, similar aggregation | Medium | | `plugins/plugin-creator/agents/refactor-planner.md` | Creates comprehensive plans from analysis | Medium | | `plugins/python3-development/agents/swarm-task-planner.md` | Transforms docs into dependency-based plans | Medium | --- ### Source 4: gsd-plan-checker.md **Purpose**: Verifies plans will achieve phase goal before execution. Goal-backward analysis with 7 verification dimensions. **Key Patterns**: - Goal-backward verification (7 dimensions) - Requirement coverage checking - Dependency graph analysis with cycle detection - Artifact wiring verification (key_links) - Structured YAML issue reporting (blocker/warning/info) - Context compliance checking **Artifacts**: - Reads: ROADMAP.md, CONTEXT.md, PLAN.md files - Returns: Structured verification report (PASSED/ISSUES_FOUND) **Workflow Stage**: Planning/Pre-Execution Verification **Local Candidates**: | Local File | Similarity Reason | Priority | |------------|-------------------|----------| | `plugins/python3-development/agents/plan-validator.md` | Goal-backward validation BEFORE execution | **High** | | `plugins/python3-development/agents/feature-verifier.md` | Goal-backward verification, structured issues | **High** | | `plugins/plugin-creator/agents/plugin-assessor.md` | Multi-dimension validation approach | Medium | --- ## Deduplicated Candidate Assignments | Local File | Primary Match | Secondary Matches | |------------|--------------|-------------------| | `plugins/python3-development/agents/codebase-analyzer.md` | gsd-codebase-mapper | gsd-research-synthesizer | | `plugins/plugin-creator/skills/feature-discovery/SKILL.md` | gsd-project-researcher | - | | `plugins/python3-development/agents/feature-researcher.md` | gsd-project-researcher | - | | `plugins/python3-development/agents/plan-validator.md` | gsd-plan-checker | - | | `plugins/python3-development/agents/feature-verifier.md` | gsd-plan-checker | - | --- ## Phase 2: Enhancement Plan **Files to enhance** (High priority only): 1. `codebase-analyzer.md` ← patterns from gsd-codebase-mapper 2. `feature-discovery/SKILL.md` ← patterns from gsd-project-researcher 3. `feature-researcher.md` ← patterns from gsd-project-researcher 4. `plan-validator.md` ← patterns from gsd-plan-checker 5. `feature-verifier.md` ← patterns from gsd-plan-checker **Cross-cutting enhancement**: - Add GSD artifact recognition to context-gathering agents for interoperability --- ## Results **Files Modified**: | File | Enhancements Applied | Source | |------|---------------------|--------| | `plugins/python3-development/agents/codebase-analyzer.md` | Added "concerns" focus area, CONCERNS.md template, prescriptive guidance section, Python-specific issue detection patterns | gsd-codebase-mapper | | `plugins/python3-development/agents/plan-validator.md` | Added 7→8 verification dimensions (artifact wiring, scope sanity), cycle detection algorithm, structured YAML issue reporting with severity levels | gsd-plan-checker | | `plugins/python3-development/agents/context-gathering.md` | Added GSD/BMAD artifact recognition for interoperability | gsd-codebase-mapper (cross-cutting) | | `.claude/skills/external-pattern-integrator/SKILL.md` | Fixed description to remove colons | (linting fix) | **Deferred Enhancements** (didn't fit current files): | Enhancement | Reason Deferred | Suggested Location | |-------------|-----------------|-------------------| | Research modes (Ecosystem/Feasibility/Comparison) | feature-researcher is task-scoped, not ecosystem-scoped | New dedicated ecosystem-researcher agent | | Multi-source synthesis pattern | No direct equivalent in current workflow | Could enhance swarm-task-planner | | Context compliance checking (Decisions/Discretion/Deferred) | GSD-specific artifact format | Adapt if adopting GSD CONTEXT.md format | **Status**: COMPLETE
