Run evidence-backed UI acceptance. Use after generating a page, or when the user wants a design review or recirculatable critique against declared goals and success criteria.
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
# ui-evaluator **Evaluator** contract: turn **declarations** into checks. Do not invent new taste standards. Every issue **points back** to a declaration. ## Steps ### 1. Bind declarations Identify which of these apply to this surface (repo files, prior turns, or design-playbook defaults): `spec` · `domain` · `craft` · `design` · `components` · `template`. When a verified `.scratch/<run>/design-baseline/state.json` binds a baseline (`status: ready`, path from `baseline.path`), include it as the project-specific visual declaration. It can support design-drift findings but is never L6 runtime proof by itself. An explicit `status: waived` disables baseline-drift checks for that run; it does not waive `spec`, accessibility, or craft checks. When `.scratch/<run>/reference/contract.md` exists (ADR-0011), you **may** use it as supporting context for findings about copied brand chrome, distinctive illustration, or other **Do not copy** breaches (`source` = `reference` or the owning declaration). It is **never** L6 proof and never a Pass/Fail gate by itself. **Done when:** the check set is named; if `spec` L6 exists, every criterion and its required proof are on the list. …

How to install
mdr add bandersnatch0x/design-playbook/ui-evaluator@sha256:0f053aaf5a8c3afeThe line at the top of this page pins the label git:20260924.e1cfa82, 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.
