Claude Code Offers 'Hooks' Feature for Workflow Automation

The Hooks feature can be utilized to solve the problem of Claude Code arbitrarily skipping certain steps or deciding a task is 'good enough' and skipping it when performing work.

Hooks are Shell commands configured to run at specific points in Claude's workflow, and they are forcibly executed regardless of Claude's judgment. The key features are as follows:

• PostToolUse: Automatically runs a formatter such as Prettier after file modifications to maintain consistency.
• PreToolUse: Preemptively blocks modifications to sensitive files such as .env or package-lock.json.
• Notification: Supports user multitasking through macOS notifications during operation.
• Stop: Automatically runs the test suite after task completion for verification.

Configuration can be managed in JSON format in the .claude/settings.json file, or conveniently set up through the interactive /hooks menu within Claude Code. When a command is executed, Exit code 0 allows normal progress, while Exit code 2 blocks the action and delivers an error message back to Claude as feedback.
