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.

if [ -f bun.lock ] || [ -f bun.lockb ]; then bun run build
