Implementation Plan

Transform PRD.md and specs/ into an actionable PLAN.md with phased tasks.

Workflow

1. Check Prerequisites

Look for PRD.md and specs/README.md in project root.

If PRD.md missing: Ask:

"No PRD.md found. Would you like me to:

1. Create one first - Run /prd to define requirements
2. Proceed without it - I'll ask you to describe requirements directly"

If specs/README.md missing: Ask:

"No specs/ found. Would you like me to:

1. Create specs first - Run /specs to define technical approach
2. Proceed without them - Plan will be less precise"

Read all available docs: PRD.md, specs/README.md, and all specs/*.md files.

2. Generate PLAN.md

Create PLAN.md at project root:

# Plan: [Title from PRD]

## Overview
Brief summary of what we're building and success criteria (from PRD).

## Architecture Reference
Link to specs/README.md and summary of key architectural decisions.

## Tasks

### Phase 1: [Phase Name]
- [ ] **Task title** `[pending]`
  - Spec: specs/component.md#section (if applicable)
  - Scope: What this task covers
  - Acceptance: How we know it's done

### Phase 2: [Phase Name]
...

## Dependencies
External dependencies or prerequisites.

## Open Questions
Unresolved questions that may affect implementation.

Task generation rules:

• Create 10-25 tasks organized into logical phases
• Each task independently completable
• Reference specific spec files where applicable
• Include setup/infrastructure tasks at start
• Include validation/testing tasks throughout
• Status values: pending | in-progress | blocked | done
• Checkbox rule: Only use [ ] checkboxes for actionable tasks that a developer or agent can complete. Never use checkboxes for questions, decisions, open items, or anything that cannot be accomplished by an agent executing code/commands.

3. Review Plan

Ask:

"I've created PLAN.md with [N] tasks across [M] phases. Would you like me to:

1. Review the plan - Check for gaps and spec coverage
2. Done - Proceed with the plan as-is"

If review requested, spawn Explore subagent:

Prompt: "Review PLAN.md against PRD.md and specs/. Check:
- Does the plan cover all requirements from PRD?
- Does each spec component have corresponding tasks?
- Are task dependencies correct?
- Are acceptance criteria testable?

Return: 🔴 Critical gaps, 🟡 Missing coverage, 🟢 Well-covered areas."

Present findings. Ask user what to update. Make requested changes.

4. Next Steps

"Plan is ready. Would you like me to:

1. Start implementation - Begin working on the first task
2. Done - Keep the plan for manual execution"
