When to Use This Skill

Check if planning is needed:

bpsai-pair intent should-plan "user's request here"

Use this skill for: features, refactors, multistep work. Skip planning for: typo fixes, small bugs, documentation tweaks.

Workflow

1. Clarify Requirements

• Restate the goal in 1–3 sentences
• Identify affected components
• Ask clarifying questions if ambiguous
• Research existing code patterns

2. Propose Approaches

Present 2–3 options with pros/cons and recommend one.

3. Create Plan

bpsai-pair plan new <slug> --type feature --title "Title"

4. Add Tasks

Task format in .paircoder/tasks/:

---
id: TASK-XXX
title: Task title
status: pending
priority: P0  # P0=must, P1=should, P2=nice
complexity: 30  # 10-100 scale
---

## Objective
- What this accomplishes.

## Acceptance Criteria
- [ ] Criterion 1
- [ ] Tests pass

## Dependencies
- Requires TASK-YYY (if any)

5. Sync to Trello

bpsai-pair plan sync-trello <plan-id> --target-list "Planned/Ready"

6. Implement Each Task

1. bpsai-pair task update TASK-XXX --status in_progress
2. Write tests first (see implementing-with-tdd skill)
3. Implement feature
4. Complete via managing-task-lifecycle skill
