Can I use hooks to block dangerous commands?

Yes, PreToolUse hooks can inspect tool inputs and block execution by exiting with a non-zero code, making them ideal for security and validation.

How do I configure these hooks?

Hooks are configured within your `.claude/settings.json` file, where you define matchers (regex) and the specific commands or scripts to execute.

Do hooks support multi-step automation?

Yes, the 'hooks' property accepts an array of commands that execute sequentially, allowing for complex workflows like formatting, linting, and testing in a single trigger.

What information do hooks receive?

Depending on the hook type, they receive metadata such as tool names, input arguments, prompt text, or session data to enable context-aware automation.

What are Claude Code hooks?

Hooks are lifecycle callbacks that execute at specific points in the Claude Code workflow, such as before a tool runs (PreToolUse) or after a user submits a prompt (UserPromptSubmit).
