## What it does

The `write-plan` skill writes its output into `docs/.plans/YYMMDD-HHmm-<plan-slug>/`. You get `SUMMARY.md` plus one file per phase named `phase-XX-<name>.md`. Each phase carries an objective, a complexity and risk level (`S`, `M`, `L`, `XL`), ordered tasks, verification commands and acceptance criteria.

It works in steps. First it loads only the project context that matters, starting from `docs/SUMMARY.md` when that file exists. Then it asks clarifying questions through the input tool to pin down scope and success criteria. After that it designs the phases and, if uncertainty is high, does research. Templates for the artifacts live in `references/summary-template.md` and `references/phase-template.md`.

Planning is all it does. No code gets written and production files stay untouched, apart from the plan artifacts themselves. The `--non-visualize` flag skips the `visualize` skill. Plans are built to survive `/clear` or a handoff to another agent, so nothing should depend on the current chat. When external research isn't available, the skill falls back to local evidence and lists its assumptions.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add buiducnhat/cobrew --skill write-plan -a claude-code
```

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

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add buiducnhat/cobrew --skill write-plan -a codex
```

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

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add buiducnhat/cobrew --skill write-plan -a cursor
```

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

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install buiducnhat/cobrew write-plan
```

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

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add buiducnhat/cobrew --skill write-plan -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/buiducnhat/cobrew --path plugins/cobrew/skills/write-plan
```

### Windsurf (Devin Desktop)

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

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add buiducnhat/cobrew --skill write-plan -a opencode
```

### Claude.ai

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

Where a file is given instead of a command, copy the files from the source to that path: https://github.com/buiducnhat/cobrew/tree/HEAD/plugins/cobrew/skills/write-plan/SKILL.md

## When to use it
- split a large change into verifiable phases
- hand a task to another agent with full context
- record assumptions and risks before coding starts
- resume work after `/clear` from the plan folder
- scope a migration or refactor without editing code

## Example prompts
- Write a phased plan for migrating to the new DB schema, with verification commands
- write-plan: break the TypeScript conversion into phases
- Plan the payment provider swap, don't touch any code

# Write Plan

## Overview

Produce a complete, self-contained implementation plan that can be executed by `execute-plan` with minimal ambiguity, even after `/clear` or by another agent.

This skill is for planning only:

- Do not implement code
- Do not modify production files (except plan artifacts)

## Workflow

### Step 1: Contextualize

Load only the project context relevant to the requested change:

- If `docs/SUMMARY.md` exists, read it first.
- Load only task-relevant detail docs.
- Prioritize `Code Standard` docs for implementation conventions.
- If docs conflict with code or user intent, use the available input/question tool before broad changes.

Then inspect only the code areas relevant to the requested change.

Capture:

- User-visible purpose and expected outcome
- Existing patterns to follow
- Constraints and dependencies
- Files, modules, commands, and docs that orient the executor
- Risks, assumptions, and unknowns

### Step 2: Initialize Plan Artifacts

1. Create: `docs/.plans/YYMMDD-HHmm-<plan-slug>/`
2. Create:
   - `SUMMARY.md`
   - one phase file per implementation phase with naming convention `phase-XX-<name>.md`
3. Add `research/` only if needed.

#### Rules:

- Use timestamp commands from the shared General Principles for folder and document timestamps.

### Step 3: Clarify Requirements

Ask clarifying questions to resolve any ambiguity in the request. Focus on:

- Scope and boundaries
- Success criteria
- Constraints and non-goals
- Priorities and trade-offs

#### Rules:

- If requirements are already clear or come from the brainstorm context, no need the confirmation step.
- Use input/question tool for gathering answers, context.
- State assumptions explicitly in `SUMMARY.md`. If multiple interpretations of the request exist, list them and ask — never pick silently.

### Step 4: Define Strategy and Phases

Design a phased strategy that is safe and verifiable.

Each phase should have:

- A clear objective
- The complexity and risk level appropriate to the phase with values: `S`, `M`, `L`, `XL`
- Ordered tasks
- Verification commands
- Observable acceptance criteria and exit criteria

Granularity rule:

- Tasks should be small, concrete each.
- Prefer phases that can be resumed safely. Document idempotency, recovery notes, or rollback constraints for risky work.
