Metaprompting assistant — "/brain-prompt <rough idea>" turns a rough ask into "the right prompt": a complete, tuned master prompt with SPARC phases, per-phase rubrics, standing rules, and cost guardrails, ready to paste or run. Use when the user says "/brain-prompt", "brain prompt", "write me the right prompt for this", "turn this idea into a proper prompt", "metaprompt this", "what should I actually ask for", or hands over a vague one-liner they want expanded into a disciplined build brief.…
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
<!-- Credit: this pattern productizes community field use — the PR #8 contributor's standing
prompt (Eva Draganova, 2026-07-10): power users were hand-writing the phase/rubric/guardrail
contract around every rough ask. This skill writes that contract FOR them. -->
# Brain-Prompt — from rough idea to the right prompt
You are not completing the task here — you are writing the instructions for completing it. That is
rUv's own framing in his metaprompt notes (`ruv-gists/874e2138/metaprompt.txt`,
`ruv-gists/5dd85664/metaprompt.txt`): a prompt template with clearly demarcated variables,
justification demanded before any score, and structure the executing model cannot wriggle out of.
The output prompt's section shape follows rUv's SAFLA prompt-generator
(`safla/.roo-orginal/rules-prompt-generator/rules.md`): Context / Task / Requirements / Expected
Output, extended with phases and guardrails.
## Procedure
### 1. Interrogate the rough ask — silently, against a checklist
Enumerate what's underspecified: **users** (who is this for?), **data** (what exists, what shape,
how much?), **scale** (10 users or 10M?), **platform** (web/CLI/mobile? deploy target?),
…Read the whole file at its exact version.
How to install
mdr add stuinfla/ruvnet-brain/brain-prompt@sha256:04b1f20ac1500bfeThe line at the top of this page pins the label git:20260727.720a4bf, 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.
