pdca-batch

name	pdca-batch
classification	workflow
classification-reason	Batch PDCA management persists regardless of model advancement
deprecation-risk	none
effort	high
description	Manage multiple PDCA features as independent parallel cycles (no shared scope/budget). For multiple features that share scope, budget, or timeline as one cohesive initiative, use /sprint (v2.1.13) — sprint groups features into a single 8-phase container, while pdca-batch keeps them independent. Triggers: pdca-batch, batch, multiple features

PDCA Batch Skill

User-invocable skill for managing multiple PDCA features and batch operations.

Arguments

Argument	Description	Example
(none)	Show all active features (same as status)	/pdca-batch
status	Show all active features and their PDCA status	/pdca-batch status
plan <f1> <f2> ...	Plan multiple features in sequence	/pdca-batch plan auth search api
manage	Interactive dashboard for parallel features	/pdca-batch manage

Action Details

status (Default)

Show all active PDCA features and their current status.

1. Read .bkit/state/pdca-status.json
2. Filter to active features (exclude archived/completed unless --all flag)
3. For each feature, display: phase, matchRate, iterationCount, last updated
4. Show summary: total active, total completed, total archived
5. Warn if approaching max parallel limit (3)

Output Format:

--- PDCA Feature Dashboard ------------------------
Active Features: 2/3 (max)

  #  Feature            Phase     Match%  Iter  Last Updated
  1  user-auth          check     85%     2/5   10 min ago
  2  search-api         design    -       0/5   2 hours ago
  -  (1 slot available)

Completed (recent):
  3  payment-flow       archived  96%     3/5   2 days ago

---------------------------------------------------
Totals: 2 active | 1 completed | 0 stale
Tip: Use /pdca-batch manage for interactive control

plan ...

Plan multiple features in a batch sequence.

1. Parse feature names from arguments (space-separated)
2. Validate: max 5 features per batch plan
3. Check current active feature count (max 3 concurrent)
4. For features exceeding the parallel limit, queue them
5. Display batch plan summary and ask for confirmation via AskUserQuestion
6. On confirmation, for each feature sequentially: a. Initialize feature in pdca-status.json (state: idle) b. Create Plan document using plan template c. Record batch origin: batchId in feature metadata
7. Display batch plan results

Batch Plan Output:

--- Batch Plan Results ----------------------------
Batch ID: batch-1710842700000
Features planned: 3

  Feature       Status    Plan Document
  auth          OK        docs/01-plan/features/auth.plan.md
  search        OK        docs/01-plan/features/search.plan.md
  api-v2        QUEUED    (waiting for slot, 2/3 active)

---------------------------------------------------
Next: Run /pdca design <feature> for each planned feature

Constraints:

• Maximum 5 features per batch plan command
• Maximum 3 features active simultaneously
• Features beyond the limit are queued with phase: queued
• Queued features auto-activate when a slot becomes available

manage

Interactive dashboard for managing parallel features.

1. Read all active features from pdca-status.json
2. Display interactive-style management panel
3. Show available actions per feature
4. Accept user input for next action via AskUserQuestion

Output Format:

--- Feature Management Dashboard ------------------
Active Features: 2/3

[1] user-auth (check, 85%, iter 2/5)
    Actions: [a]nalyze  [i]terate  [r]eport  [p]ause

[2] search-api (design, -, iter 0/5)
    Actions: [d]esign-review  [n]ext  [p]ause

[Q] user-input (queued, waiting for slot)
    Actions: [c]ancel  [p]rioritize

---------------------------------------------------
Global Actions:
  [s] Switch active feature
  [n] New feature (if slot available)
  [r] Refresh dashboard
  [x] Exit dashboard
---------------------------------------------------
Select feature number or action:

Management Actions:

Action	Description
Switch feature	Change which feature is "focused" for subsequent /pdca commands
Prioritize queued	Move a queued feature to next available slot
Pause feature	Temporarily halt a feature's PDCA progression
Cancel queued	Remove a feature from the queue
New feature	Start a new PDCA cycle if slot available

Parallel Feature Rules

1. Maximum 3 concurrent features: Prevents context overload and resource contention
2. Independent state: Each feature has its own phase, matchRate, and iteration count
3. Shared guardrails: Automation level and trust score are global (not per-feature)
4. Queue system: Features beyond limit are queued and auto-activated on slot availability
5. Isolation: Features do NOT share checkpoints or audit entries

State File Schema

Features in pdca-status.json with batch support:

    "batchId": "batch-1710842700000",
    "queuePosition": null,
    "lastUpdated": "2026-03-19T10:30:00.000Z"
  },
  "search-api": {

Module Dependencies

Module	Function	Usage
lib/pdca/status.js	getPdcaStatus()	Read all feature states
lib/pdca/status.js	updatePdcaStatus()	Update feature state

lib/pdca/lifecycle.js	activateQueuedFeature()	Auto-activate from queue
lib/audit/audit-logger.js	writeAuditLog()	Record batch operations

Usage Examples

# View all features

# Interactive management
/pdca-batch manage

Integration with /pdca

The /pdca-batch skill complements the main /pdca skill:

Scope	Use /pdca	Use /pdca-batch
Single feature operations	Yes	No
Multi-feature overview	No	Yes
Phase transitions	Yes	No (redirects to /pdca)
Batch planning	No	Yes
Feature switching	No	Yes (manage)

When using /pdca commands, they operate on the currently "focused" feature. Use /pdca-batch manage to switch the focused feature.
