Action Details

plan (Plan Phase)

1. Check if docs/01-plan/features/{feature}.plan.md exists

2. If not, create based on plan.template.md

3. Create Task: [Plan] {feature}

4. Context Anchor Generation: After generating Plan document, extract Context Anchor (WHY/WHO/RISK/SUCCESS/SCOPE) from Executive Summary, Requirements, and Risk sections. Write as ## Context Anchor table between Executive Summary and Section 1.

   Dimension	Content
   WHY	Core problem being solved
   WHO	Target users/stakeholders
   RISK	Top 3 risks identified
   SUCCESS	Measurable success criteria
   SCOPE	In-scope / out-of-scope boundary

design (Design Phase)

1. Verify Plan document exists
2. Create docs/02-design/features/{feature}.design.md
3. Create Task: [Design] {feature} (blockedBy: Plan)
4. Context Anchor Embed: Copy Plan's ## Context Anchor table to Design document top (between header metadata and ## 1. Overview). If Plan has no Context Anchor, skip gracefully.
5. Generate 3 Architecture Options:
   • Option A — Minimal Changes: Least modification, maximum reuse
   • Option B — Clean Architecture: Best separation of concerns
   • Option C — Pragmatic Balance: Good boundaries without over-engineering
6. Present comparison table with trade-offs (complexity, maintainability, effort, risk)
7. Ask user which option to select before proceeding

do (Do Phase)

1. Verify Design document exists
2. Provide implementation guide
3. Create Task: [Do] {feature} (blockedBy: Design)
4. Full Upstream Context Loading: Read ALL upstream documents:
   • PRD (docs/00-pm/{feature}.prd.md) — WHY context
   • Plan (docs/01-plan/features/{feature}.plan.md) — Context Anchor, Success Criteria
   • Design document — architecture decisions
5. Decision Record Chain Display:

   Decision Record Chain
   [PRD] Target: {segment} — {rationale}
   [Plan] Architecture: {option} — {rationale}
   [Design] Pattern: {approach} — {rationale}
   

6. Display Context Anchor from Design document header
7. Parse --scope parameter: If --scope module-1 provided, filter implementation guide to matching modules only from Design's Session Guide
8. Ask user to confirm scope before starting implementation

analyze (Check Phase)

1. Call gap-detector agent
2. Compare Design vs implementation
3. Calculate Match Rate
4. Create Task: [Check] {feature}
5. After gap-detector analysis, also call bkit_iterate MCP tool for quantitative gap measurement:
   • This tool compares design document vs actual implementation
   • Returns matchRate percentage and specific gaps with file references
   • If matchRate < 90%, recommend calling /pdca iterate

iterate (Act Phase)

1. Check results (when matchRate < 90%)
2. Call pdca-iterator agent
3. Auto-fix and re-verify
4. Max 5 iterations
5. Call bkit_iterate MCP tool for automated gap analysis:
   • Input: feature name, project directory, target match rate (default 90%)
   • Tool returns gaps with specific file:line references
   • Fix the identified gaps
   • Call bkit_iterate again to re-check
   • Repeat until matchRate >= 90% or max 5 iterations
   • Server tracks iteration count internally

qa (QA Phase)

When running QA, call bkit_qa_run MCP tool:

• Input: feature name, project directory, test levels [1,2,3,4,5]
• The tool auto-detects test framework (jest/vitest/playwright)
• L1: Unit tests, L2: API tests, L3-L5: E2E/browser tests (if playwright installed)
• Review results: passRate, coverage, defects
• If passRate < 95%, fix issues and re-run

report (Completion Report)

1. Verify Check >= 90%
2. Call report-generator agent
3. Create completion report
4. Load ALL upstream documents for comprehensive reporting:
   • PRD — compare original value proposition vs delivered value
   • Plan — compare planned Success Criteria vs actual results
   • Design — note architecture decisions and any deviations
   • Analysis — include final Match Rate
5. Include Decision Record summary and Success Criteria final status
