Use when user can only recognize what they want by seeing it.
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
# Brainstorm and prototypes
The user has unknown knowns: criteria they can't verbalize but will recognize on sight. Finding those during prototyping is cheap; finding them mid-implementation is expensive, because small spec changes can mean drastically different code. Give them things to react to.
## Steps
1. Establish scope first: what is being decided (layout? approach? data model? tone?) and what is explicitly out of scope. One decision per round.
2. Produce 3-5 variations that are **wildly different, not shades of the same idea**. If two variations would get the same reaction, replace one.
3. Make them cheap and disposable:
- Visual/UX → a single self-contained HTML file with fake data, no backend, no state.
- Approaches → a one-screen sketch of each: the idea, what it optimizes for, its sharpest tradeoff.
- Ranked lists → order from cheapest to most ambitious so the user can draw their line.
4. Label each variation with the belief it bets on ("this one assumes density beats whitespace"), so the user's reaction reveals the underlying criterion, not just a preference.

How to install
mdr add jpeetz/agent-skills/brainstorm-prototypes@sha256:25ae0a5961921a58The line at the top of this page pins the label v1.0.0, 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.
