# gjalla-breakdown

This skill turns a finished feature spec into dependency-ordered work waves and small tasks. Use it before implementation when progress needs a clear structure.

## What it does

gjalla-breakdown reads a feature specification or agent plan, extracts behavior and technical changes, and arranges the work into sequential waves. Tasks in the same wave can run in parallel; later waves wait for their prerequisites.

Each task gets an identifier such as `W1-T1`, a short change summary, exact file paths, dependency references, and an acceptance check. The breakdown also covers documentation, tests, and verification. A task is kept to 1–2 files so its diff stays small and reviewable.

Run the skill after the specification is ready. Its guidance keeps one specification below 20 tasks; a larger feature should be split into several specifications. The resulting breakdown stays beside the design so implementation status can be marked as each wave lands.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add gjalla/engineering --skill gjalla-breakdown -a claude-code
```

2. **Manually: put the files in place**
- File: `~/.claude/skills/gjalla-breakdown/SKILL.md` — Copy the whole skill folder; for one project use .claude/skills/gjalla-breakdown/

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add gjalla/engineering --skill gjalla-breakdown -a codex
```

2. **Manually: put the files in place**
- File: `.agents/skills/gjalla-breakdown/SKILL.md` — For all projects use ~/.agents/skills/

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add gjalla/engineering --skill gjalla-breakdown -a cursor
```

2. **Manually: put the files in place**
- File: `.cursor/skills/gjalla-breakdown/SKILL.md` — Cursor also reads .agents/skills/ and .claude/skills/

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install gjalla/engineering gjalla-breakdown
```

2. **Manually: put the files in place**
- File: `.github/skills/gjalla-breakdown/SKILL.md`

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add gjalla/engineering --skill gjalla-breakdown -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/gjalla/engineering --path skills/gjalla-breakdown
```

### Windsurf (Devin Desktop)

**Manually: put the files in place**
- File: `.devin/skills/gjalla-breakdown/SKILL.md` — The legacy .windsurf/skills/ path still works

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add gjalla/engineering --skill gjalla-breakdown -a opencode
```

### Claude.ai

**Claude.ai**
- Zip the folder and upload it in Settings → Capabilities → Skills

## When to use it
- split a feature specification into tasks
- order work by dependency
- group parallel work into waves
- define file paths and acceptance checks
- include tests and documentation in the plan

## Example prompts
- Break this finished feature specification into dependency-ordered waves.
- Give every task an ID, exact file paths, and an acceptance check.
- Add testing and documentation tasks where the specification requires them.
