## What it does

This skill guides pre-implementation discovery for uncertain features. It begins by scanning repository context, inspecting `docs/SUMMARY.md`, coding standards, and existing dependencies. It then asks focused questions about objectives, non-goals, and constraints instead of diving into code immediately.

Next, the skill generates two to five viable technical options. Each option includes pros, trade-offs, and an estimated complexity score. Once an approach is picked, the agent drafts the foundation, interface contracts, error handling, and testing strategies step by step.

The workflow forbids altering production files during the session. If chosen, final notes export straight into `docs/.brainstorms/` as standardized Markdown summaries.

## Install

### Claude Code (native platform)

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

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

### Codex

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

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

### Cursor

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

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

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install buiducnhat/cobrew brainstorm
```

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

### Gemini CLI

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

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

### Windsurf (Devin Desktop)

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

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add buiducnhat/cobrew --skill brainstorm -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/brainstorm/SKILL.md

## When to use it
- clarify project scope and non-goals before writing code
- evaluate trade-offs and complexity across several design options
- document data models, error handling, and verification plans
- save structured brainstorming artifacts into the repository

## Example prompts
- /brainstorm redesign the authentication flow to support passkeys
- /brainstorm evaluate background worker architecture for video exports
- /brainstorm migrate local file storage to S3

# Brainstorm

## Overview

Use this skill to convert rough ideas into clear, reviewable design outputs through structured dialogue.

The goal is to:

1. Clarify requirements and constraints
2. Explore alternatives with trade-offs
3. Produce a concrete, validated design brief in artifacts or a handoff to planning

## Workflow

### Step 1: Gather Project Context

Load only the project context relevant to the current idea:

- 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 interactive input/question tool before broad changes.

Also check key implementation files relevant to the idea and note constraints from existing architecture, dependencies, and conventions.

Keep this pass focused. Only gather what is needed for the current idea.

### Step 2: Clarify Requirements

Ask targeted questions sequentially to remove ambiguity with interactive input/question tool:

- Focus on:
  - Objective and user value
  - Scope boundaries
  - Constraints (technical, UX, performance, timeline)
  - Success criteria
  - Non-goals

Do not jump to implementation details too early.

### Step 3: Explore Approaches

Propose 2-5 viable approaches.

For each approach, include:

- Short summary
- Pros
- Cons / risks
- Complexity estimate
- Recommended use conditions

Lead with your recommended option and explain why it best fits the project context and constraints.

After presenting all approaches, use interactive input/question tool to let the user pick their preferred approach. List the summary options. Example:

- Approach A, short summary
- Approach B, short summary
- Approach C, short summary
- Other (please specify)

with the tag added for the recommended approach to guide the user.

### Step 4: Present the Design Incrementally

After user selection, present the design incrementally with sections:

- **1. Foundation** - Problem framing, goals, and proposed architecture/flow.
- **2. Technical Details** - Data model, interfaces, error handling, edge cases and risks.
- **3. Delivery** - Testing/verification strategy and rollout considerations (if applicable).

After presenting, use input/question tool immediately to ask whether to:

1. Proceed to the next step
2. Adjust the design (require typing)

### Step 5: Close the Loop

After you and the user have worked through requirements and the design is validated, determine the next actions.

Use input/question tool to present the user with three high-level next actions:

- "Write plan immediately" - skip the artifact step and move straight to a `write-plan` handoff with visualization.
```
