# Task briefs

Each file here is a self-contained brief for a sub-session (typically Sonnet) to execute one chunk of work. Briefs assume the executor has read [`/CLAUDE.md`](../../CLAUDE.md) — do not restate the stack or architecture there.

## How to use a brief

1. Read `/CLAUDE.md` first.
2. Read the task file end-to-end.
3. Stop when **all** acceptance criteria pass. Do not bolt on extra scope.
4. If a brief turns out to be wrong, update the brief in the same commit as the code.

## Brief format

Every task file has these sections:

- **Goal** — one sentence.
- **Why** — what this unlocks; how it fits the larger plan.
- **Depends on** — task numbers that must be done first.
- **Scope** — bullet list of what to build.
- **Out of scope** — explicit non-goals to prevent drift.
- **Acceptance criteria** — checkable list. Done = all checked.
- **Notes** — gotchas, recommended libs, sketches.
