Hook Development

Event-driven automation hooks for Claude Code are created by implementing prompt-based or command-based scripts that trigger on specific events like PreToolUse, PostToolUse, Stop, and SessionStart to execute automated validation workflows.

Yes, you can enforce security checks before file operations by building a PreToolUse hook that intercepts tool calls and validates file write operations to prevent unauthorized or malicious actions before execution.

Multi-stage validation in Claude Code plugin workflows chains conditional execution logic across different event hooks, allowing you to verify complex conditions like requiring corresponding tests for code changes before the agent stops.

Project context is loaded automatically when a session starts by configuring a SessionStart hook, which triggers context retrieval and state initialization processes across cross-event workflows for the agent environment.

No external dependencies are required to implement cross-event workflows; the hook development process relies entirely on internal scripts and references to manage state and conditional execution across PreToolUse, PostToolUse, and Stop events.
