Unified Skill for managing PDCA cycle. Supports the entire Plan → Design → Do → Check → Act flow.

Arguments

Action Details

pm (PM Analysis Phase)

Run PM Agent Team for product discovery and strategy analysis before Plan phase.

1. Call pm-lead Agent (orchestrates 4 sub-agents)
2. pm-lead runs Phase 1: Context Collection (project info, git history)
3. pm-lead runs Phase 2: Parallel Analysis (3 agents simultaneously)
   • pm-discovery: Opportunity Solution Tree (Teresa Torres)
   • pm-strategy: Value Proposition (JTBD 6-Part) + Lean Canvas
   • pm-research: 3 Personas + 5 Competitors + TAM/SAM/SOM
4. pm-lead runs Phase 3: PRD Synthesis via pm-prd agent
   • Beachhead Segment (Geoffrey Moore) + GTM Strategy
   • 8-section PRD generation
5. Output PRD to docs/00-pm/{feature}.prd.md
6. Create Task: [PM] {feature}
7. Update .bkit/state/pdca-status.json: phase = "pm"
8. Guide user to next step: /pdca plan {feature}

Output Path: docs/00-pm/{feature}.prd.md

Requirements:

• Agent Teams enabled: CLAUDE_CODE_EXPERIMENTAL_AGENT_TEAMS=1
• Project level: Dynamic or Enterprise (Starter not supported)

plan (Plan Phase)

0. Template Loading: Read ${CLAUDE_PLUGIN_ROOT}/templates/plan.template.md to understand the required Plan document structure and sections. Use this template's sections as your document outline. This is MANDATORY — do not generate Plan documents from memory or assumptions.
1. PRD Auto-Reference: Check if docs/00-pm/{feature}.prd.md exists
   • If found: Read PRD and use as context for Plan document (improves quality significantly)
   • If not found: Proceed normally (tip: run /pdca pm {feature} first for better results)
2. Check if docs/01-plan/features/{feature}.plan.md exists
3. If not, create based on plan.template.md
4. If exists, display content and suggest modifications
5. Checkpoint 1 — Requirements Confirmation: Present understanding of the feature (problem, scope, constraints) and use AskUserQuestion: "요구사항 이해가 맞나요? 빠진 건 없나요?" Wait for user confirmation before proceeding.
6. Checkpoint 2 — Clarifying Questions: Identify underspecified elements (edge cases, error handling, integration points, compatibility). Present organized question list. Wait for answers before generating the document.
7. Generate Plan document with user-confirmed requirements
8. Complete predecessor Task first: If a [PM] {feature} Task exists and is still in_progress, use TaskList to find it and TaskUpdate it to status: "completed" before creating the Plan Task (see Phase Transition Rule). Then Create Task: [Plan] {feature}
9. Update .bkit/state/pdca-status.json: phase = "plan"
10. Write ## Executive Summary at document top with 4-perspective table (Problem/Solution/Function UX Effect/Core Value), each 1-2 sentences
11. 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. This anchor propagates to Design/Do documents for cross-session context continuity.
12. MANDATORY: After completing the document, also output the Executive Summary table in your response so the user sees it immediately without opening the file

Output Path: docs/01-plan/features/{feature}.plan.md

Tip: For features with ambiguous requirements or multiple implementation approaches, use /plan-plus {feature} instead. Plan Plus adds brainstorming phases (intent discovery, alternatives exploration, YAGNI review) before document generation for higher-quality plans.

design (Design Phase)

0. Template Loading: Read ${CLAUDE_PLUGIN_ROOT}/templates/design.template.md to understand the required Design document structure. Use this template's sections as your document outline. This is MANDATORY — do not generate Design documents from memory or assumptions.
1. Verify Plan document exists (required - suggest running plan first if missing)
2. Read Plan document to understand requirements and scope
3. PRD Context Loading: Check if docs/00-pm/{feature}.prd.md exists. If found, read the Executive Summary and Beachhead/GTM sections to inform architecture decisions with market context. This prevents strategic context loss at the Plan→Design handoff.
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 (legacy), skip this step gracefully.
5. Generate 3 Architecture Options (inspired by feature-dev Phase 4):
   • Option A — Minimal Changes: Least modification, maximum reuse of existing code. Fast but potentially coupled.
   • Option B — Clean Architecture: Best separation of concerns, most maintainable. More files, more refactoring.
   • Option C — Pragmatic Balance: Good boundaries without over-engineering. Recommended default.
6. Present comparison table with trade-offs (complexity, maintainability, effort, risk)
7. Checkpoint 3 — Architecture Selection: Use AskUserQuestion: "3가지 설계안 중 어떤 걸 선택하시겠습니까?" Include recommendation. Wait for user selection.
8. Create docs/02-design/features/{feature}.design.md using selected architecture
9. Use design.template.md structure + reference Plan content
10. Session Guide Generation: Analyze Design's ## 11. Implementation Guide structure to generate Module Map and Recommended Session Plan. Add as ### 11.3 Session Guide within Implementation Guide section. This enables /pdca do {feature} --scope module-N for multi-session incremental implementation.
11. Design Anchor Integration (Pencil MCP): If the feature involves UI and Pencil MCP is available:
    • Suggest: "UI 컨셉 페이지를 1-2개 먼저 만든 후 /design-anchor capture {feature} 로 디자인 토큰을 잠그세요"
    • If Design Anchor already exists (docs/02-design/styles/{feature}.design-anchor.md), embed it in the Design document as ## Design Anchor section
    • This ensures design tokens (colors, typography, spacing) are locked before implementation
12. Complete predecessor Task first: Use TaskList to find the [Plan] {feature} Task (and any earlier phase Task for this feature still in_progress) and TaskUpdate each to status: "completed" — this resolves the blockedBy chain and prevents stale phase status from leaking into prompt context (see Phase Transition Rule). Then Create Task: [Design] {feature} (blockedBy: Plan task)
13. Update .bkit/state/pdca-status.json: phase = "design"

Output Path: docs/02-design/features/{feature}.design.md

do (Do Phase)

1. Verify Design document exists (required)
2. Read Design document FULLY (read the entire document, not just a summary. This is critical — full context reload ensures each session starts with complete architectural context)
3. Full Upstream Context Loading (Phase 2+3): Load the COMPLETE upstream document chain:
   • Read PRD (docs/00-pm/{feature}.prd.md) — extract WHY context (JTBD, value proposition, market positioning)
   • Read Plan (docs/01-plan/features/{feature}.plan.md) — extract Context Anchor, Success Criteria, Requirements
   • This ensures implementation decisions are guided by strategic intent from PRD→Plan→Design, not just the Design spec
4. Decision Record Chain Display: Extract and display key decisions from PRD→Plan→Design as a unified chain. Format:

   📋 Decision Record Chain
   [PRD] Target: {market/user segment} — {rationale}
   [Plan] Architecture: {selected option} — {rationale}
   [Design] State Mgmt: {selected approach} — {rationale}

5. Success Criteria Tracking: Extract Success Criteria from Plan document. Display as implementation checklist — each criterion must be addressed during implementation. Mark criteria that are covered by the current --scope.
6. Parse --scope parameter: If arguments contain --scope <value>, extract module list (comma-separated scope keys). Match against Design's Session Guide Module Map. Filter implementation items to show only matching modules.
7. Display Context Anchor: Show the Context Anchor table from Design document header. Format: "📌 Context Anchor" + WHY/WHO/RISK/SUCCESS/SCOPE table. This reminds the user WHY we're building this feature.
8. Session Guide Display:
   • If no --scope: Show full Module Map from Design + recommend session split + proceed with full implementation guide
   • If --scope provided: Show only the selected modules' implementation items
9. Summarize implementation scope:
   • Files to create: N
   • Files to modify: M
   • Estimated changes: ~X lines
10. Checkpoint 4 — Implementation Approval: Present scope summary and use AskUserQuestion: "이 범위로 구현을 시작해도 되겠습니까?" DO NOT START IMPLEMENTATION WITHOUT USER APPROVAL.
11. After approval, provide implementation guide based on do.template.md
12. Reference implementation order from Design document (filtered by --scope if provided)
13. Code Comment Convention (Phase 3): During implementation, add Design reference comments for key architectural decisions:
    • At module/file level: // Design Ref: §{section} — {decision rationale}
    • At critical logic: // Plan SC: {success criteria being addressed}
    • These comments create traceable links from code back to design decisions
14. Complete predecessor Task first: Use TaskList to find the [Design] {feature} Task (and any earlier phase Task for this feature still in_progress) and TaskUpdate each to status: "completed" — this resolves the blockedBy chain and prevents stale phase status from leaking into prompt context (see Phase Transition Rule). Then Create Task: [Do] {feature} (blockedBy: Design task)
15. Update .bkit/state/pdca-status.json: phase = "do"

--scope Parameter:

/pdca do feature                      # Full scope (backward compatible) + session guide
/pdca do feature --scope module-1     # Only module-1
/pdca do feature --scope module-1,module-2  # Multiple modules

Guide Provided:

• Context Anchor (WHY/WHO/RISK/SUCCESS/SCOPE)
• Session scope (filtered or full)
• Implementation order checklist
• Key files/components list
• Dependency installation commands

analyze (Check Phase)

1. Verify Do completion status (implementation code exists)
2. Full Upstream Context Loading (Phase 2+3): Load the COMPLETE upstream document chain for comprehensive evaluation:
   • Read PRD (docs/00-pm/{feature}.prd.md) — verify strategic alignment (was the right problem solved?)
   • Read Plan (docs/01-plan/features/{feature}.plan.md) — verify Requirements fulfillment + Success Criteria
   • Read Design (docs/02-design/features/{feature}.design.md) — verify structural implementation match
   • This 3-layer verification catches gaps that single-document comparison misses
3. Context Anchor Embed: Copy Context Anchor from Design to Analysis document header.
4. Strategic Alignment Check (Phase 3): Before structural gap analysis, verify:
   • Does the implementation address the PRD's core problem (WHY)?
   • Are Plan Success Criteria met or on track?
   • Were key Design decisions (architecture, data model, API) followed?
   • Flag strategic misalignments as Critical regardless of structural match rate
5. Plan Success Criteria Reference: Evaluate each Success Criteria from Plan:
   • Mark as ✅ Met / ⚠️ Partial / ❌ Not Met
   • Include evidence (file:line or test result)
   • Criteria violations are automatically Critical severity
6. Call gap-detector Agent (v2.3.0: Static Analysis + Runtime Verification Plan)
   • gap-detector performs static analysis (Structural + Functional + Contract)
   • gap-detector outputs a Runtime Verification Plan (L1/L2/L3 test specs)
7. Compare Design document vs implementation code on 3 static axes:
   • Structural Match: File existence, route coverage, component list
   • Functional Depth: Placeholder detection, Page UI Checklist verification, actual logic completeness
   • API Contract: 3-way verification (Design §4 ↔ Server route.ts ↔ Client fetch calls)

8. Runtime Verification (v2.3.0): After gap-detector completes, execute runtime tests.

   • Preferred: Run existing tests from tests/e2e/{feature}.spec.ts (written during Do phase)
   • Fallback: If no test file exists, generate from gap-detector's Runtime Verification Plan
   • Test scenarios are defined in Design §8 Test Plan, implemented during Do phase, executed here

   L1 — API Endpoint Tests (always run if server is available):

   • Execute each curl command from gap-detector's L1 plan
   • Check: HTTP status code matches expected
   • Check: Response JSON shape matches expected (has .data, .error, .pagination)
   • Check: Auth guard returns 401 for protected endpoints
   • Check: Zod validation returns 400 with fieldErrors for invalid input
   • Check: Rate limiting returns 429 after threshold
   • Detect server: curl -s -o /dev/null -w "%{http_code}" http://localhost:3000/
   • If no server running: skip L1, warn user, use static-only formula

   L2 — UI Action Tests (run if Playwright is installed):

   • Generate Playwright test file from gap-detector's L2 plan
   • Write to tests/e2e/{feature}-actions.spec.ts
   • Run: npx playwright test tests/e2e/{feature}-actions.spec.ts
   • Each test: navigate to page → perform action → assert result
   • Check: API calls triggered by UI match expected endpoints
   • If Playwright not installed: skip L2, suggest pnpm add -D @playwright/test

   L3 — E2E Scenario Tests (run if Playwright is installed):

   • Generate Playwright test file from gap-detector's L3 plan
   • Write to tests/e2e/{feature}-e2e.spec.ts
   • Run: npx playwright test tests/e2e/{feature}-e2e.spec.ts
   • Full user journey: multi-page flows with state persistence
   • Check: complete flow from start to end without errors

   Match Rate Formula (v2.3.0):

   If runtime executed:
     Overall = (Structural × 0.15) + (Functional × 0.25)
             + (Contract × 0.25) + (Runtime × 0.35)
   If static only (no server):
     Overall = (Structural × 0.2) + (Functional × 0.4) + (Contract × 0.4)

9. Calculate Match Rate and generate Gap list. Report all rates separately.
10. Decision Record Verification (Phase 3): Check if key decisions from Decision Record Chain were followed in implementation. Flag deviations.
11. Checkpoint 5 — Review Decision: Present issues by severity (Critical/Important only, confidence ≥80%). Use AskUserQuestion with options:
    • "지금 모두 수정" — proceed to iterate
    • "Critical만 수정" — iterate critical only
    • "그대로 진행" — accept current state Wait for user decision before proceeding.
12. Complete predecessor Task first: Use TaskList to find the [Do] {feature} Task (and any earlier phase Task for this feature still in_progress) and TaskUpdate each to status: "completed" — this resolves the blockedBy chain and prevents stale phase status from leaking into prompt context (see Phase Transition Rule). Then Create Task: [Check] {feature} (blockedBy: Do task)
13. Do not copy the match rate by hand. When gap-detector finishes, bkit records its Overall Match Rate as matchRate (and metric M1) and moves the phase to "check". Confirm with /pdca status. Write matchRate to .bkit/state/pdca-status.json yourself only when status shows it as not measured, or when the L1–L3 runtime results changed the Overall from gap-detector's value.

Output Path: docs/03-analysis/{feature}.analysis.md

qa (QA Phase)

1. Verify Iterate completion (Match Rate ≥ target or max iterations reached)
2. Delegate to qa-phase skill: Invoke the standalone /qa-phase {feature} skill, which owns L1-L5 test planning, generation, execution, and reporting.
3. The qa-phase skill:
   • Reads Design doc §8 Test Plan
   • Calls qa-test-planner to refine L1-L5 test specs
   • Calls qa-test-generator to emit runnable test files
   • Executes L1 (API) / L2 (UI actions) / L3 (E2E) tests via Chrome MCP
   • Optional L4 (perf) / L5 (security) for Enterprise level
4. Emit one of:
   • QA_PASS → auto-advance to report phase
   • QA_FAIL → fall back to iterate phase
   • QA_SKIP → mark qa as skipped, proceed to report
5. Complete predecessor Task first: Use TaskList to find the [Check] {feature} Task and the latest [Act-N] {feature} Task (and any earlier phase Task for this feature still in_progress) and TaskUpdate each to status: "completed" (see Phase Transition Rule). Then Create Task: [QA] {feature}
6. Update .bkit/state/pdca-status.json: phase = "qa", qaStatus = <PASS|FAIL|SKIP>

Output Path: docs/05-qa/{feature}.qa-report.md

Agent: bkit:qa-lead (mapped via frontmatter agents.qa)

iterate (Act Phase)

1. Check results (when matchRate < 90%)
2. Call pdca-iterator Agent
3. Auto-fix code based on Gap list
4. After pdca-iterator returns, re-run Check by calling the gap-detector Agent yourself (a subagent cannot start another subagent). Its new Overall Match Rate moves the phase from "act" back to "check".
5. Complete predecessor Task first: Use TaskList to find the [Check] {feature} Task and any prior [Act-*] {feature} Task for this feature still in_progress and TaskUpdate each to status: "completed" (see Phase Transition Rule). Then Create Task: [Act-N] {feature} (N = iteration count)
6. Stop when >= 90% reached or max iterations (5) hit

Iteration Rules:

• Max iterations: 5 (adjustable via bkit.config.json)
• Stop conditions: matchRate >= 90% or maxIterations reached

report (Completion Report)

0. Template Loading: Read ${CLAUDE_PLUGIN_ROOT}/templates/report.template.md to understand the required Report document structure. Use this template's sections as your document outline. This is MANDATORY — do not generate Report documents from memory or assumptions.
1. Verify Check >= 90% (warn if below)
2. Full Upstream Context Loading (Phase 2+3): Load ALL upstream documents for comprehensive reporting:
   • Read PRD — compare original value proposition vs delivered value
   • Read Plan — compare planned Requirements/Success Criteria vs actual results
   • Read Design — note architecture decisions and deviations
   • Read Analysis — include final Match Rate and resolved gaps
   • This ensures the report reflects the FULL journey from PRD→Code
3. Call report-generator Agent
4. Integrated report of PRD, Plan, Design, Implementation, Analysis
5. Decision Record Summary (Phase 3): Include section "Key Decisions & Outcomes":
   • List decisions from PRD→Plan→Design chain
   • For each: was it followed? what was the outcome?
   • This creates a learnable record for future PDCA cycles
6. Success Criteria Final Status: Include Plan Success Criteria with final status:
   • Each criterion: ✅ Met (with evidence) / ❌ Not Met (with reason)
   • Overall Success Rate: X/Y criteria met
7. Include ## Executive Summary with ### 1.3 Value Delivered reflecting actual results (4 perspectives with metrics)
8. MANDATORY: After completing the report, also output the Executive Summary table in your response
9. Complete predecessor Task first: Use TaskList to find the [QA] {feature} Task (or the [Check] {feature} / latest [Act-N] {feature} Task if QA was skipped) and any earlier phase Task for this feature still in_progress, and TaskUpdate each to status: "completed" (see Phase Transition Rule). Then Create Task: [Report] {feature}
10. Update .bkit/state/pdca-status.json: phase = "completed"

Output Path: docs/04-report/{feature}.report.md

team (Team Mode) - v1.5.1

Start PDCA Team Mode using Claude Code Agent Teams (requires CLAUDE_CODE_EXPERIMENTAL_AGENT_TEAMS=1).

team [feature] - Start Team Mode

1. Check if Agent Teams is available: call isTeamModeAvailable() from lib/team/coordinator.js
2. If not available, display: "Agent Teams is not enabled. Set CLAUDE_CODE_EXPERIMENTAL_AGENT_TEAMS=1 to enable."
3. Detect project level via detectLevel() - Starter projects cannot use Team Mode
4. Generate team strategy via generateTeamStrategy(level):
   • Dynamic: 3 teammates (developer, frontend, qa) — CTO Lead orchestrates
   • Enterprise: 5 teammates (architect, developer, qa, reviewer, security) — CTO Lead orchestrates
5. CTO Lead (cto-lead agent, fable) automatically:
   • Sets technical direction and selects orchestration pattern
   • Distributes tasks to teammates based on PDCA phase
   • Enforces quality gates (90% Match Rate threshold)
6. Show strategy and confirm with AskUserQuestion before starting
7. Assign PDCA tasks to teammates via assignNextTeammateWork()

team status - Show Team Status

1. Call formatTeamStatus() from lib/team/coordinator.js
2. Display: Team availability, enabled state, display mode, teammate count
3. Show current PDCA feature progress per teammate if active

Output Example:

📊 PDCA Team Status
─────────────────────────────
Agent Teams: Available ✅
Display Mode: in-process
Teammates: 4 / 4 (Enterprise)
─────────────────────────────
Feature: user-auth
  architect: [Design] in progress
  developer: [Do] waiting
  qa: idle
  reviewer: idle

team cleanup - Cleanup Team Resources

1. Stop all active teammates
2. Record team_session_ended in PDCA history via addPdcaHistory()
3. Return to single-session PDCA mode
4. Display: "Returning to single-session mode"

Required Environment: CLAUDE_CODE_EXPERIMENTAL_AGENT_TEAMS=1

Level Requirements:

archive (Archive Phase)

1. Verify Report completion status (phase = "completed" or matchRate >= 90%)
2. Complete the terminal Task: Use TaskList to find the [Report] {feature} Task and any other [Phase] {feature} Task for this feature still in_progress, and TaskUpdate each to status: "completed" — the feature is terminal, so no phase Task should remain open (see Phase Transition Rule).
3. Verify PDCA documents exist (plan, design, analysis, report)
4. Create docs/archive/YYYY-MM/{feature}/ folder
5. Move documents (delete from original location)
6. Update Archive Index (docs/archive/YYYY-MM/_INDEX.md)
7. Update .bkit/state/pdca-status.json: phase = "archived", record archivedTo path
8. Remove feature from status (or preserve summary with --summary option)

Arguments:

Output Path: docs/archive/YYYY-MM/{feature}/

Documents to Archive:

• docs/01-plan/features/{feature}.plan.md
• docs/02-design/features/{feature}.design.md
• docs/03-analysis/{feature}.analysis.md
• docs/04-report/features/{feature}.report.md

FR-04: Summary Preservation Option (v1.4.8):

When using --summary (or --preserve-summary, -s), the feature data in .bkit/state/pdca-status.json is converted to a lightweight summary instead of being deleted:

// Summary format (70% size reduction)
{
  "my-feature": {
    "phase": "archived",
    "matchRate": 100,
    "iterationCount": 2,
    "startedAt": "2026-01-15T10:00:00Z",
    "archivedAt": "2026-01-20T15:30:00Z",
    "archivedTo": "docs/archive/2026-01/my-feature/"
  }
}

Use --summary when you need:

• Historical statistics and metrics
• Project duration tracking
• PDCA efficiency analysis

Important Notes:

• Cannot archive before Report completion
• Documents are deleted from original location after move (irreversible)
• Feature name must match exactly
• Default behavior: complete deletion from status
• Use --summary to preserve metrics for future reference

cleanup (Cleanup Phase) - v1.4.8

Clean up archived features from .bkit/state/pdca-status.json to reduce file size.

1. Read archived features from .bkit/state/pdca-status.json
2. Display list with timestamps and archive paths
3. Ask user for confirmation via AskUserQuestion (FR-06)
4. Delete selected features from status using cleanupArchivedFeatures()
5. Report cleanup results

Arguments:

Output Example:

🧹 PDCA Cleanup
─────────────────────────────
Archived features found: 3

1. feature-a (archived: 2026-01-15)
2. feature-b (archived: 2026-01-20)
3. feature-c (archived: 2026-01-25)

Select features to cleanup:
[ ] All archived features
[ ] Select specific features
[ ] Cancel

Related Functions (lib/pdca/status.js):

• getArchivedFeatures() - Get list of archived features
• cleanupArchivedFeatures(features?) - Cleanup specific or all archived
• deleteFeatureFromStatus(feature) - Delete single feature
• enforceFeatureLimit(max=50) - Auto cleanup when limit exceeded

Notes:

• Only archived/completed features can be deleted
• Active features are protected from deletion
• Archive documents remain in docs/archive/ (only status is cleaned)

status (Status Check)

1. Read the status through getPdcaStatusView() (lib/pdca/status.js), never the file alone. It returns the stored .bkit/state/pdca-status.json with any feature whose phase is evidenced only by its documents filled in, and marks each feature's source as status-file or documents. .bkit-memory.json is a deprecated v1.6.0 legacy path that no lib module reads or writes; the migrated .bkit/state/memory.json holds the 9-phase pipeline status, which is a different thing from the PDCA phase.
2. Display current feature, PDCA phase, Task status
3. Visualize progress
4. For any feature whose source is documents, add one line: phase read from documents — no run recorded it. Do not present it as a recorded phase, and do not write it to the status file from here.

Output Example:

📊 PDCA Status
─────────────────────────────
Feature: user-authentication
Phase: Check (Gap Analysis)
Match Rate: 85%
Iteration: 2/5
─────────────────────────────
[Plan] ✅ → [Design] ✅ → [Do] ✅ → [Check] 🔄 → [Act] ⏳

next (Next Phase)

1. Check current PDCA phase — through getPdcaStatusView(), for the reason given under status above
2. Suggest next phase guide and commands
3. Confirm with user via AskUserQuestion

Task Integration

Each PDCA phase automatically integrates with Task System:

Task Creation Pattern:
┌────────────────────────────────────────┐
│ [PM] {feature}                         │
│   ↓ (optional, pre-Plan)               │
│ [Plan] {feature}                       │
│   ↓ (blockedBy)                        │
│ [Design] {feature}                     │
│   ↓ (blockedBy)                        │
│ [Do] {feature}                         │
│   ↓ (blockedBy)                        │
│ [Check] {feature}                      │
│   ↓ (blockedBy, Check < 90%)           │
│ [Act-1] {feature}                      │
│   ↓ (on iteration)                     │
│ [Act-N] {feature}                      │
│   ↓ (Check >= 90%)                     │
│ [Report] {feature}                     │
│   ↓ (after Report completion)          │
│ [Archive] {feature}                    │
└────────────────────────────────────────┘

Phase Transition Rule (task completion)

The diagram above shows task creation. Advancing a phase also requires task completion:

Before creating a new phase's Task, mark every prior [Phase] {feature} Task for this feature that is still in_progress as completed — use TaskList to find them and TaskUpdate {status: "completed"} on each. The archive action likewise completes the terminal [Report] Task.

Why this matters: a blockedBy chain is only semantically correct when the predecessor is completed by the time the successor is created. More importantly, Claude Code surfaces the native Task list into ambient prompt context every turn. If a predecessor Task is left in_progress, that stale phase (e.g. "design" during a "do" phase) keeps leaking back to the user — disagreeing with .bkit/state/pdca-status.json's phase field, which is the phase source of truth. Completing predecessors keeps the two in sync. Each phase action above embeds this step immediately before its Create-Task step.

Legacy Commands Mapping

Output Style Integration (v1.5.1)

PDCA workflows benefit from the bkit-pdca-guide output style:

/output-style bkit-pdca-guide

This provides PDCA-specific response formatting:

• Phase status badges: [Plan] -> [Design] -> [Do] -> [Check] -> [Act]
• Gap analysis suggestions after code changes
• Next-phase guidance with checklists
• Feature usage report integration

When running PDCA commands, suggest this style if not already active.

Agent Teams Integration (v1.5.1)

For Dynamic/Enterprise projects, PDCA phases can run in parallel using Agent Teams:

/pdca team {feature}        Start parallel PDCA
/pdca team status            Monitor teammate progress
/pdca team cleanup           End team session

Suggest Agent Teams when:

• Feature is classified as Major Feature (>= 1000 chars)
• Match Rate < 70% (parallel iteration can speed up fixes)
• Project level is Dynamic or Enterprise
