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-memory.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. 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)
1. Check if docs/01-plan/features/{feature}.plan.md exists
2. If not, create based on plan.template.md
3. If exists, display content and suggest modifications
4. Create Task: [Plan] {feature}
5. Update .bkit-memory.json: phase = "plan"
6. Write ## Executive Summary at document top with 4-perspective table (Problem/Solution/Function UX Effect/Core Value), each 1-2 sentences
7. 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)

1. Verify Plan document exists (required - suggest running plan first if missing)
2. Create docs/02-design/features/{feature}.design.md
3. Use design.template.md structure + reference Plan content
4. Create Task: [Design] {feature} (blockedBy: Plan task)
5. Update .bkit-memory.json: phase = "design"

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

do (Do Phase)

1. Verify Design document exists (required)
2. Provide implementation guide based on do.template.md
3. Reference implementation order from Design document
4. Create Task: [Do] {feature} (blockedBy: Design task)
5. Update .bkit-memory.json: phase = "do"

Guide Provided:

• Implementation order checklist
• Key files/components list
• Dependency installation commands

analyze (Check Phase)

1. Verify Do completion status (implementation code exists)
2. Call gap-detector Agent
3. Compare Design document vs implementation code
4. Calculate Match Rate and generate Gap list
5. Create Task: [Check] {feature} (blockedBy: Do task)
6. Update .bkit-memory.json: phase = "check", matchRate

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

iterate (Act Phase)

1. Check results (when matchRate < 90%)
2. Call pdca-iterator Agent
3. Auto-fix code based on Gap list
4. Auto re-run Check after fixes
5. 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)

1. Verify Check >= 90% (warn if below)
2. Call report-generator Agent
3. Integrated report of Plan, Design, Implementation, Analysis
4. Include ## Executive Summary with ### 1.3 Value Delivered reflecting actual results (4 perspectives with metrics)
5. MANDATORY: After completing the report, also output the Executive Summary table in your response
6. Create Task: [Report] {feature}
7. Update .bkit-memory.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, opus) 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:

Level	Available	Teammates	CTO Lead
Starter	No	-	-
Dynamic	Yes	3	cto-lead (opus)
Enterprise	Yes	5	cto-lead (opus)

archive (Archive Phase)

1. Verify Report completion status (phase = "completed" or matchRate >= 90%)
2. Verify PDCA documents exist (plan, design, analysis, report)
3. Create docs/archive/YYYY-MM/{feature}/ folder
4. Move documents (delete from original location)
5. Update Archive Index (docs/archive/YYYY-MM/_INDEX.md)
6. Update .pdca-status.json: phase = "archived", record archivedTo path
7. Remove feature from status (or preserve summary with --summary option)

Arguments:

Argument	Description	Example
archive {feature}	Archive with complete cleanup (default)	/pdca archive user-auth
archive {feature} --summary	Archive with summary preservation (FR-04)	/pdca archive user-auth --summary

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 .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 .pdca-status.json to reduce file size.

1. Read archived features from .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:

Argument	Description	Example
cleanup	Interactive cleanup (shows list)	/pdca cleanup
cleanup all	Delete all archived features	/pdca cleanup all
cleanup {feature}	Delete specific feature	/pdca cleanup old-feature

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 .bkit-memory.json
2. Display current feature, PDCA phase, Task status
3. Visualize progress

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
2. Suggest next phase guide and commands
3. Confirm with user via AskUserQuestion

Phase Guide:

Current	Next	Suggestion
None	pm	/pdca pm [feature] (recommended) or /pdca plan [feature]

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

CTO-Led Team Orchestration Patterns:

Level	Plan	Design	Do	Check	Act
Dynamic	leader	leader	swarm	council	leader
Enterprise	leader	council	swarm	council	watchdog

Slash Invoke Pattern (CC 2.1.0+)

Skills 2.0 enables direct slash invocation for all PDCA commands:

• /pdca plan [feature] — Create Plan document
• /pdca design [feature] — Create Design document
• /pdca do [feature] — Implementation guide
• /pdca analyze [feature] — Gap analysis (Check phase)
• /pdca iterate [feature] — Auto-improvement (Act phase)
• /pdca report [feature] — Completion report
• /pdca status — Current PDCA status
• /pdca next — Next phase guide
• /plan-plus [feature] — Brainstorming-enhanced planning

Hot reload: SKILL.md changes reflect without session restart (CC 2.1.0+).

PDCA Auto-Monitoring (CC v2.1.71+)

CC v2.1.71 introduces /loop command and Cron tools for automated monitoring.

Usage Examples

• /loop 5m /pdca status - Check PDCA status every 5 minutes
• /loop 10m /pdca analyze [feature] - Run Gap analysis every 10 minutes
• Use Cron tools for session-level scheduled checks

CTO Team Integration

• Long CTO Team sessions benefit from /loop for progress monitoring
• stdin freeze fixed in v2.1.71 ensures reliable long sessions
• Background agent recovery (v2.1.71) makes background: true agents reliable
