Use when the user wants to capture a feature as a brief or spec before planning it -- "arma un brief para esto", "necesito un spec antes de planear", "definamos el alcance de la feature", "write a brief for this", "spec this out before we plan 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

# Brief Spec

Brief Spec is how the orchestrator turns what it agreed with the user into a
brief: an objective, observable acceptance criteria, the decisions taken, and
the boundaries, ready for gaia-planner. The brief is the contract the plan is
audited against, so the orchestrator owns its content and owns checking the
plan that comes back.

## The database is the brief

A brief is a row in `briefs` plus its child rows (`acceptance_criteria`,
`brief_decisions`, `milestones`), written and read only through `gaia brief`.
What `gaia brief show` prints is a rendering of those rows: nothing on disk is
authoritative and there is no file to write. Code or docs that still describe
`.claude/project-context/briefs/` are legacy -- flag them in
`cross_layer_impacts` instead of editing them as a side effect.

**Execution follows authority.** The orchestrator co-creates the brief and may
use its trusted Gaia CLI lane for bounded reads and user-confirmed
`new`/headless `edit`/`set-status`/AC/decision writes. `gaia-operator` remains
the alternative for batching or operational separation. Destructive deletion is
outside the direct lane. The orchestrator owns the questions, confirmation,
…

How to install

The exact contents, by fingerprint
mdr add metraton/gaia/brief-spec@sha256:502c9d042d8d662c

The line at the top of this page pins the label git:20260925.3549fb0, 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.
