Claude Code Hooks: Extending Functionality with User-Defined Shell Commands
2025-07-01
Claude Code introduces hooks, user-defined shell commands that execute at various stages of its lifecycle. This allows for deterministic control over Claude Code's behavior, ensuring actions like automatic code formatting, logging, and custom permission checks always occur. Hooks transform suggestions into reliable application-level code, enhancing functionality and simplifying workflows. While powerful, users must prioritize security and ensure commands are safe and reliable.
