# /plan — Generate PRD and Sprint Contracts
Read a spec or feature description, decompose it into stories, and write `.loop/prd.json` and `.loop/contracts/`. This skill does NOT write any project source code or start the loop.
## STOP: What This Skill Does NOT Do
- Does NOT write any project source code (no .js, .py, .ts, .html, .css, etc.)
- Does NOT start the loop or invoke /agent-loop:run
- Does NOT make git commits to project code
## Prerequisites
`.loop/config.json` must exist. If not, tell the user to run `/agent-loop:init` first and stop.
## Steps
### 1. Find the feature spec or description
Check these locations for an existing spec:
- `docs/superpowers/specs/*.md`
- `docs/specs/*.md`
- `SPEC.md`, `PRD.md`, `DESIGN.md` at project root
If found: "I found a spec at `{path}`. Using it."
If not found, check if the user passed a description as an argument. If nothing: ask "What do you want to build? 1-3 sentences."
### 2. Analyze the project
- Read relevant source directories
- Check for existing tests and conventions
- Run `git log --oneline -20` if git history exists
### 3. Ask 2-3 clarifying questions
Only questions where human judgment is needed. Do NOT ask what you can answer from the code or spec.
### 4. Generate prd.json
**CRITICAL: Use this EXACT schema. The loop orchestrator will break if you deviate.**
Write `.loop/prd.json`:
```json
{
"project": "<project name>",
"branchName": "loop/<feature-slug>",
"description": "<one-line description>",
"userStories": [
{
"id": "US-001",
"title": "Short descriptive title",
"description": "What this story delivers",
"acceptanceCriteria": [
"Specific, verifiable criterion",
"Another criterion"
],
"priority": 1,
"passes": false,
"notes": "",
"rejections": 0
}
]
}
```
**Rules:**
- Top-level array key MUST be `userStories`. Not `sprints`, `stories`, or `tasks`.
- IDs: `US-001`, `US-002`, etc.
- `passes`: always `false`. `notes`: always `""`. `rejections`: always `0`.
- Each priority is unique (1 = highest).
- Each story fits in one agent context window (1-3 files changed).
- Acceptance criteria must be independently verifiable — not "works well" but "returns X when given Y".
### 5. Generate sprint contracts
Create `.loop/contracts/` directory. For each story, write `.loop/contracts/{id}.contract.md`:
```markdown
# Sprint Contract: {id} — {title}
## What Will Be Built
Concrete deliverable description.
## Done Conditions
- [ ] Specific testable condition
- [ ] All acceptance criteria from prd.json met
## Evaluation Criteria
- [ ] What the evaluator checks
- [ ] No regressions
## Out of Scope
- Things NOT in this story
## Key Files
- path/to/file — what changes
## Dependencies
- Depends on: [IDs or "none"]
- Blocks: [IDs or "none"]
```
### 6. Initialize progress.md
Write `.loop/progress.md`:
```markdown
# Progress
## Codebase Patterns
- [Patterns from analysis]
---
## Session Log
### Planning Session
Date: {today}
**PRD created:** {N} stories for "{description}"
---
```
### 7. Present for review
> **Plan Ready — Review Before Running**
>
> | Stories | Mode | Branch |
> |---------|------|--------|
> | {N} | {mode} | {branchName} |
>
> **Stories:**
> 1. US-001: {title}
> 2. US-002: {title}
> ...
>
> **Review before running:**
> - `.loop/prd.json` — stories and acceptance criteria
> - `.loop/contracts/` — done conditions per story
>
> When ready:
> ```
> /agent-loop:run
> ```
**STOP HERE. Do NOT start the loop. Wait for the user to run /agent-loop:run explicitly.**
