Ultracite
haydenbleasel · App
Ultracite is a command line that configures a linter and formatter for JavaScript and TypeScript projects, in single repositories and monorepos. An interactive setup asks which toolchain, framework, editor and AI agents you use, then installs and configures everything. It generates rule and context files for a range of AI agents so people and models share one style, and further commands check code, fix it and diagnose the setup. It suits developers who write code alongside AI agents.
Written by ooruby from the README of ultracite 7.12.4.

Why it's useful
You and your AI agents get one shared set of style rules without hand-writing separate configuration for each tool.
What you could do with it
- Run the interactive setup in a project to pick Biome, ESLint or Oxlint and configure your editor and agents.
- Check or fix lint issues across the whole project, or only the files and globs you name.
- Hand the lint problems it cannot fix to Claude Code or Codex and have them repaired file by file.
Written from its documentation: what it says it can do, not what our checks found.
Maintenance
Not measuredNo release date is on record for this package yet. The nightly publisher check records one as it reaches each npm package, about once every ten nights.
Release activity only: it says nothing about quality or safety, and a finished small package can be fine without releases. How it is measured
- Command execution is bounded
- inventory
- eval (skills/ultracite/SKILL.md:110)
- eval (skills/ultracite/references/code-standards.md:67)
- An inventory of where the code starts another program, not a verdict on this row: whether each one runs a fixed program or whatever it is handed takes a reading by hand.
- Data handling disclosed
- finding
- no statement of what it reads, writes or sends (README.md)
Published because it was found. A finding is information about where the limits are, not a verdict that the software is unsafe.
What this does not cover
- Everything. Treat it as you would software from anywhere else.

In its maker's words
The AI-ready formatter that helps you write and generate code faster.

Static scanned
- What it establishes
- Its published package, or for a hosted server its source repository at a recorded commit, was read file by file, without running it, by every check in our current scan.
- What it does not
- How it behaves when it runs, or anything the scan does not read yet: several rubric checks, the repository's history, and compiled code in folders named dist or build. For a hosted server, that the endpoint runs the code that was read. The ooruby Index sets out exactly what was read.
- Exactly what was read
- Version 7.12.4, the file with digest sha512-6jVEwaZBaytFm6XRoI3WGS2ZydrkrNvHTD0qTf7983ti2FlEWL1YcxnPaMaYuS6PkXqMhIK2XGr0cbsL4x5pQA==, as the registry publishes it. A published version cannot be replaced, so this names the same bytes for anyone who checks.
- Authentication
- Runs locally. No hosted endpoint is listed for this package. You run it on your own machine, so there is no endpoint of ours to authenticate against.
Adding it
Run it with:
npx -y ultracite@7.12.4Pinned to 7.12.4, which is the version the findings above were found in. Drop the version to take whatever is newest, and the report on this page stops describing what you installed.
