Create one stable, traceable result contract for a capable fresh agent.

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

# Mission Brief

Use **mission command**: freeze an adopted result, its proof, and its hard boundaries while leaving the route to the executing Agent.

A Mission Brief is a result contract, not a proposal review, final design, implementation plan, or execution request. When a request needs another product too, keep the products separate and settle any decision that defines the commission before freezing it.

If a request for a final plan or design through this Skill leaves the deliverable unclear, explain the difference and ask which product is wanted. Do not promise both a plan and a Brief without authorization, even while waiting for missing source material.

## Principles

- **Outcome over route.** The executing Agent has fresher workspace and environment evidence, so specify what must become true and let it choose a viable route.
- **Source status.** An **Authority Source** can bind the Mission; a **Reference Source** preserves useful knowledge without becoming binding merely because it is retained or linked.

How to install

The exact contents, by fingerprint
mdr add sumo91/mission-brief/mission-brief@sha256:60341a45d6385bcb

The line at the top of this page pins the label git:20260905.2fa31fc, 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.
