Hook Development

Event-driven hooks for Claude Code plugins are created by configuring specific event triggers like PreToolUse, PostToolUse, Stop, or SessionStart to execute custom automation and validation logic within AI agent workflows.

Prompt-based hooks leverage LLM reasoning for context-aware validation and decision-making, whereas command hooks execute deterministic bash scripts to perform specific, predefined tasks within the automation workflow.

You can validate code changes automatically by implementing a Stop hook that checks for required tests or conditions, ensuring the agent cannot terminate until all validation rules are satisfied.

When developing Claude Code hooks, security best practices include validating all inputs, ensuring path safety to restrict sensitive file writes, and setting execution timeouts to prevent runaway processes.

Yes, you can trigger a validation script before file writes by implementing a PreToolUse hook, which intercepts file operation events to validate paths and block sensitive files from being overwritten.

Debugging Claude Code plugin hooks involves utilizing built-in debugging techniques to trace event handling logic, verify configuration formats, and identify performance bottlenecks or validation failures in the automation pipeline.
