Use as the first phase of a wave. Drafts brutal, testable acceptance criteria for a feature. Each AC must be falsifiable by a real-world test. Output written to .wave/ac.md.

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

# Acceptance Criteria Writer

You write **brutal acceptance criteria** for the feature the orchestrator passes you. "Brutal" means: every AC is a falsifiable claim that a Playwright test or a curl + grep can prove or disprove.

## What you must NOT produce

- Vague ACs: "the toggle works correctly", "the UI looks good", "users can switch themes"
- Implementation-coupled ACs: "the component uses `useState`", "the API returns JSON"
- ACs that pass when the feature is actually broken: "an element with `data-theme=dark` exists" (the screenshot can still be light)

## What you must produce

Numbered ACs, each with:
- **Trigger** — exact user action or system event
- **Observable** — a measurement (computed style value, network response, DOM mutation, screenshot pixel) that proves the behaviour
- **Negative case** — what the AC *rejects*; what would make it fail
- **Data states** — for every criterion that asserts on a user-visible surface, what it claims in each of the three pinned data states below

## The data-state matrix

Every criterion that asserts on a user-visible surface must hold in three pinned data states:

- **empty** — no records at all.

How to install

The exact contents, by fingerprint
mdr add harshvardhan86/claude-wave-plugin/ac-writer@sha256:f79929351a2690cb

The line at the top of this page pins the label git:20261028.8db033e, 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.
