SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes scripts (resource) and references (resource) and assets (resource) components.

What problem does it solve?

This Skill streamlines development by enabling automated responses to Claude Code events, ensuring consistency, security, and efficiency in your workflows.

Core Features & Use Cases

Event-Driven Automation: Trigger actions based on events like tool use, session start, or agent completion.
Pre-execution Validation: Validate tool calls before they run to prevent errors or security risks.
Post-execution Feedback: React to tool results for logging, analysis, or further actions.
Use Case: Automatically validate file write operations to prevent accidental modification of system files or sensitive data.

Quick Start

Use the hook development skill to add a PreToolUse hook that validates file write operations.

FAQPage Schema

How do I create event-driven hooks for Claude Code plugins?▼

Event-driven hooks for Claude Code plugins are created by defining prompt-based or command-based automation triggered by session events such as PreToolUse, PostToolUse, Stop, and SessionStart. You integrate bash scripts and LLM reasoning to execute deterministic and context-aware logic.

Can I validate tool calls before they run to prevent file modification errors?▼

Yes, you can validate tool calls before execution by implementing a PreToolUse hook. This intercepts file write operations to prevent accidental modification of system files or sensitive data, ensuring security and consistency.

What events can I trigger automation hooks on in a development workflow?▼

You can trigger automation hooks on session events including PreToolUse, PostToolUse, Stop, and SessionStart. These event-driven triggers facilitate automated validation, logging, and context-aware actions within your development workflow.

Does hook development work with bash scripts for deterministic logic execution?▼

Yes, hook development integrates directly with bash scripts to execute deterministic logic. It combines bash scripting with LLM reasoning to deliver both strict validation rules and context-aware automation for plugin workflows.

How do I add post-execution feedback to log and analyze tool results?▼

You add post-execution feedback by configuring a PostToolUse hook that reacts to tool results. This event-driven mechanism enables automatic logging, result analysis, and triggering further actions after a tool completes.

When should I not use event-driven hooks for workflow automation?▼

You should avoid event-driven hooks for logic that requires complex state management across multiple independent sessions. Hooks are designed for discrete, event-triggered validation and automation, not continuous background processing.
