hook-development

Event-driven hooks for Claude Code plugins are created by defining JSON hook configurations that execute custom logic for events like PreToolUse, PostToolUse, and SessionStart to validate tool usage and enforce security policies.

Prompt-based hooks leverage LLM reasoning for context-aware validation, such as evaluating file write safety, while command-based hooks perform fast deterministic checks like path traversal validation and environment configuration enforcement.

Security policies are enforced before tool execution by creating PreToolUse hooks that validate file write safety, check for path traversal, and restrict sensitive file access using defined JSON hook configuration schemas.

Yes, jq is required as a dependency to use this event-driven hook framework for Claude Code plugins, as the hook configurations rely on jq for JSON processing and validation.

Workflows across the development lifecycle are automated using event-driven hooks that respond to events like SessionStart and Stop, enabling custom logic execution for validation, security, and automation tasks.
