Ultracite Rules - AI-Ready Formatter and Linter.

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

# Project Context
Ultracite enforces strict type safety, accessibility standards, and consistent code quality for JavaScript/TypeScript projects using Biome's lightning-fast formatter and linter.

## Key Principles
- Zero configuration required
- Subsecond performance
- Maximum type safety
- AI-friendly code generation

## Before Writing Code
1. Analyze existing patterns in the codebase
2. Consider edge cases and error scenarios
3. Follow the rules below strictly
4. Validate accessibility requirements

## Rules

### Accessibility (a11y)
- Don't use `accessKey` attribute on any HTML element.
- Don't set `aria-hidden="true"` on focusable elements.
- Don't add ARIA roles, states, and properties to elements that don't support them.
- Don't use distracting elements like `<marquee>` or `<blink>`.
- Only use the `scope` prop on `<th>` elements.
- Don't assign non-interactive ARIA roles to interactive HTML elements.
- Make sure label elements have text content and are associated with an input.
- Don't assign interactive ARIA roles to non-interactive HTML elements.
- Don't assign `tabIndex` to non-interactive HTML elements.
- Don't use positive integers for `tabIndex` property.

How to install

The exact contents, by fingerprint
mdr add unstackedapps/opensuitemcp/.cursor/rules/ultracite.mdc@sha256:f3bdeca1f69ac6e2

The line at the top of this page pins the label git:20260126.d04bdf6, 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.
