Overview

Comprehensive Biome skills for fast JavaScript/TypeScript linting and formatting with modern tooling and performance optimization.

Skills

This plugin provides the following skills:

  • Biome Configuration - Master Biome configuration files, rules, and project setup
  • Biome Linting - Expert knowledge of Biome's linting capabilities and rule configuration
  • Biome Formatting - Formatting patterns, options, and code style management

Usage

Skills can be invoked using the Skill tool:

javascript
Skill("jutsu-biome:biome-configuration")
Skill("jutsu-biome:biome-linting")
Skill("jutsu-biome:biome-formatting")

Each skill provides specialized knowledge and patterns for Biome development.

Quality Hooks

This plugin includes hooks that ensure Biome checks pass before completing work. The hooks use @thebushidocollective/han to support both single-package and monorepo projects.

Monorepo Support

The hooks automatically detect directories with biome.json and run Biome checks in each:

bash
han hook run --fail-fast --dirs-with biome.json -- npx biome check .

This ensures all packages in your monorepo pass Biome validation before work is marked complete.

Installation

Install with npx (no installation required):

bash
han plugin install jutsu-biome

Hooks

⚠ī¸

Token Usage Notice

Hooks run automatically during Claude Code sessions and their output is sent to the model for processing. This may increase token usage and associated costs. Consider disabling hooks you don't need via han-config.yml.

🛑

Stop

Runs when the main Claude Code agent has finished responding. Can verify task completion, check quality gates, or ensure documentation requirements are met before the session ends.
