Design-first ideation gate: three parallel agents propose a simple, a scalable and a user-delight approach, rendered as a tradeoff matrix, then you pick a direction. No code is written. Use when the user asks how to build X, which approach to take, is torn between options, or types $ccc-brainstorm.

Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

What the file says

# $ccc-brainstorm — three options before code

**CC Commander** · $ccc-brainstorm · three distinct approaches, a tradeoff matrix, and one locked decision before any spec or code.

Adapted from superpowers/brainstorming (MIT licensed).

## When to use / when not to

- Use for "how should I build X", "which approach should I take", "I'm torn between X and Y", "help me decide on auth / DB / design system / API shape", "explore options for", "what are my choices for".
- Skip for a bug with an obvious fix (`$ccc-review`, or just fix it), a standard pattern with a known answer, a task with one correct answer (`$ccc-plan` directly), or a mid-implementation pivot where switching costs more than the decision is worth.

## What happens

### 1. Capture the question

If an argument was given, it is the topic. Otherwise ask with the topic picker under Decision points; when the user picks a category, ask for the specifics in one plain sentence.

### 2. Gather light context (optional)

When the topic is about the current codebase, read what grounds the options and nothing more:

```bash
git rev-parse --show-toplevel 2>/dev/null && ls
cat package.json 2>/dev/null | head -40
```
…

How to install

The exact contents, by fingerprint

mdr add kevinzai/commander/ccc-brainstorm@sha256:18b26f5cf68d541a

The line at the top of this page pins the label git:20261013.fbe187d, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
