writing-codex-briefs

Use when composing the task brief and acceptance criteria for a Codex dispatch (invoked from dispatching-to-codex). Covers the self-contained brief format and how to write acceptance checks that actually protect you — weak checks are the sneakiest way a dispatch goes wrong.

# Writing Codex Briefs

Codex sees **zero** chat history. The brief is the only channel. Anything not in it does not exist for Codex.

## The Acceptance File — `.codex/ACCEPTANCE.md`

Written and committed BEFORE dispatch. This is the frozen bar the judge will enforce.

```
GOAL: <one sentence: what "done" means>

CHECKS (all must pass, exact commands):
- `<command>` exits 0 and prints <expected>
- `<build/typecheck command>` exits 0
