Secure Claude Code hooks require input validation, path sanitization, and protection of sensitive files. Apply defensive coding practices including explicit exit codes, robust error handling, and validation of all user-supplied data before processing to prevent vulnerabilities and ensure reliable hook execution.

Hook design requires choosing the correct hook type and matchers for your use case, then validating that the hook handles edge cases, protects sensitive files, and doesn't block Claude operations. Review hooks for input validation, path handling, error codes, and performance impact before deployment.

Yes, Claude Code hooks automate tasks like code formatting on save, but must validate file paths, handle edge cases, and avoid blocking operations. Apply security validation and reliability checks to prevent vulnerabilities and ensure the hook performs consistently without disrupting Claude workflows.

Review hooks for input validation gaps, unsanitized paths, unprotected sensitive files, inadequate error handling, and missing exit codes. Apply defensive coding practices and explicit validation logic to harden hooks against injection attacks, path traversal, and file access violations.

Common issues include missing input validation, improper path handling, inadequate error handling, and unclear exit codes. Ensure hooks validate all inputs, sanitize file paths, protect sensitive files, handle errors robustly, and use explicit exit codes to communicate success and failure states.
