Deslint Documentation

The verification layer for AI-generated code.
MCP server + ESLint plugin + CLI + GitHub Action.

Choose your surface

Each works on its own. Use any one — or combine them.

MCP server

Use if: Your AI agent (Claude Code, Cursor, Codex, Windsurf) should check design quality as it writes code.

$ npx @deslint/mcp install

Vendor guides

ESLint plugin

Use if: You already run ESLint and want Deslint rules in that pipeline.

$ npm install -D @deslint/eslint-plugin

Flat-config setup

CLI

Use if: You want ad-hoc scans, local pre-commit, or CI without the GitHub Action.

$ npm install -D @deslint/cli

CLI guide

GitHub Action

Use if: You want PR comments, inline review suggestions, and a Design Health Score on every PR.

Evaluating linters?

Deslint vs. stylelint — honest comparison

Different jobs, not rivals. Side-by-side on six real questions — authored CSS, JSX drift, Tailwind arbitrary values, design tokens, CI, and AI agents.

Quick Install — recommended

$ npx @deslint/mcp install
