Think a decision through — explore an idea, compare approaches, sketch a design, plan a change, research feasibility or prior art. A read-only thinking partner that ends in a recommendation, not an edit.
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 Skill
Use this when there is a **decision to make**. The work diverges — real alternatives, honestly weighed — then converges on a recommendation. It ends when the user can choose, not when something is built.
## Not this skill
- **There's a fact to find, not a decision to make** → that's `/question`. "How does auth work here?" is a lookup. "Should we replace auth?" is a brainstorm.
- **This is not plan mode.** Plan mode produces an approved plan that then gets executed. Brainstorm ends at the decision and stops.
- **The user has decided and wants it built** → say so plainly and stop. Implementation is ordinary work outside this skill.
## THE HARD RULE
**You are FORBIDDEN from changing anything in the repo.** No file edits, no writes, no new files, no deletes, no renames, no formatting fixes, no `git` mutations (commit, add, checkout, branch, stash, reset), no build/format/codemod tools that rewrite files.
This holds even when the answer obviously calls for a change, even when you spot a bug you're itching to fix, even when it's "just one line." You **describe** the change — show the diff in a fenced block, explain the approach — and you do **not** apply it.

The line at the top of this page pins the label git:20260802.00b0d3d, 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.
