Biome Linting

What it does

This skill enables AI agents to automatically lint codebases using Biome, a fast and reliable tool for formatting and analyzing JavaScript, TypeScript, JSX, TSX, JSON, CSS, SCSS, and Markdown files. It ensures consistent code style and detects potential issues across multiple file types simultaneously.

When to use it

• Enforce strict formatting standards on large monorepos containing mixed frontend and configuration files.
• Automatically clean up code before deployment or review to reduce manual editing time.
• Validate project consistency when working with TypeScript, JSX, and CSS in a single workflow.
• Integrate into CI/CD pipelines to catch style drift early in the development cycle.

Key capabilities

• Supports linting for JavaScript, TypeScript, JSX, TSX, JSON, CSS, SCSS, and Markdown.
• Provides fast performance suitable for large-scale codebases.
• Handles formatting and analysis rules within a unified toolchain.

Example prompts

• "Run Biome linting on my entire project to check for style violations."
• "Format all TypeScript and JSON files in the repository using Biome standards."
• "Analyze the CSS and SCSS files for consistency issues using the Biome linter."

Tips & gotchas

Biome is designed for speed, making it ideal for large projects, but ensure your project includes a biome.json configuration file to define specific rules. Since this skill covers multiple languages, verify that your codebase uses compatible syntax versions for all supported file types before running the agent.
