Batch Skill

Process multiple features or tasks in parallel. Execute PDCA commands across multiple features in a single invocation.

Usage

/batch plan user-auth payment-system notification
/batch design user-auth payment-system
/batch analyze user-auth payment-system notification search
/batch report user-auth payment-system

Execution Model

1. Parse: Extract the command and feature list from arguments
2. Validate: Check that each feature has prerequisites for the requested command
3. Execute: Process each feature sequentially, tracking progress via Task Tracker
4. Report: Output a summary table showing status for each feature

Progress Tracking

Each feature creates a Task Tracker entry:

• Task subject: [Batch {command}] {feature}
• Status updates as each feature completes
• Final summary shows pass/fail per feature

Error Handling

• Fail-forward: If one feature fails, remaining features still execute
• Error log: Failed features are collected and reported at the end
• Retry option: Use --retry-failed to re-run only the failed features

/batch --retry-failed analyze user-auth payment-system

Output Format

Batch Execution Summary
----------------------------------------------
Command: plan
Features: 4 total | 3 success | 1 failed
----------------------------------------------
  user-auth        [OK]   docs/01-plan/features/user-auth.plan.md
  payment-system   [OK]   docs/01-plan/features/payment-system.plan.md
  notification     [OK]   docs/01-plan/features/notification.plan.md
  search           [FAIL] Missing prerequisite: project scope undefined
----------------------------------------------

Feature Discovery

If no features are specified, batch will auto-discover features from:

1. .pdca-status.json primary and secondary features
2. docs/01-plan/features/*.plan.md existing plan files
3. docs/02-design/features/*.design.md existing design files

/batch analyze          # auto-discovers all features
/batch report --all     # explicitly process all known features

Combination with Other Skills

Batch works with any PDCA subcommand and can be combined with loop:

/loop 1h batch analyze user-auth payment-system
