#Hooks

#Hook Mechanism

Hooks allow you to run custom scripts before and after Claude Code performs specific operations.

#Lifecycle Hooks

{
  "hooks": {
    "pre-command": "./scripts/pre-command.sh",
    "post-command": "./scripts/post-command.sh",
    "pre-commit": "./scripts/lint.sh",
    "post-commit": "./scripts/notify.sh"
  }
}

#Custom Hooks

#Example: Pre-commit Hook

#!/bin/bash
# .claude-code/hooks/pre-commit.sh

echo "Running pre-commit checks..."

# Run linter
npm run lint || exit 1

# Run tests
npm test || exit 1

echo "✓ Pre-commit checks passed"
