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:

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):

han plugin install jutsu-biome

Hooks

⚠️

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.

🛑

SubagentStop

Runs when a Claude Code subagent (Task tool call) has finished responding. Can validate subagent outputs, enforce quality standards, or trigger additional workflows after delegated tasks complete.
