Review frontend code and live pages against the Front-End Checklist (380+ rules for accessibility, performance, SEO, security, HTML, CSS, JavaScript, images, i18n, privacy, testing) using the `frontendchecklist` CLI. Use when writing, reviewing, or shipping HTML/CSS/JS/JSX/TSX/Vue/Svelte/Astro code, before a commit or PR, or when asked to audit a public URL.
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
# Front-End Checklist CLI `frontendchecklist` checks frontend code against the Front-End Checklist rules. It works offline, prints JSON when its output is piped (which is how you will usually call it), and uses exit codes you can branch on. Run it with `npx -y @frontendchecklist/cli <command>` if `frontendchecklist` is not installed. ## When to use it - After writing or editing frontend files: `frontendchecklist review <paths>`. - Before committing: `git diff --cached | frontendchecklist review -`. - When the user asks to audit a deployed page: `frontendchecklist audit https://...`. - When you need the authoritative guidance for a topic: `frontendchecklist search <topic>`, then `frontendchecklist rule <slug>`. - For a structured pass (launch, accessibility, SEO, performance): `frontendchecklist checklists`, then `frontendchecklist checklist <slug>`. ## Commands | Command | Purpose | | --- | --- | | `review <paths...\|->` | Static review of files, directories (walked; vendor dirs skipped), or stdin | | `audit <https-url>` | Fetch a public page and review its HTML | | `search [query] [--focus a,b] [-n 10]` | Find rules by keyword, technology, or category | …

How to install
mdr add thedaviddias/front-end-checklist/frontendchecklist@sha256:699424dff3501737The line at the top of this page pins the label git:20261001.9b4f0d0, 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.
