What problem does it solve?
This Skill helps you design, validate, and maintain Claude Code plugin hooks that automate decisions, enforce safety rules, and add context at the right moment without fragile ad hoc scripting.
Core Features & Use Cases
- Prompt-based hook design: Create context-aware hooks for PreToolUse, Stop, SubagentStop, and UserPromptSubmit events when you need flexible validation or approval logic.
- Command-based automation: Build deterministic hooks for tasks like session context loading, schema validation, logging, and other repeatable checks.
- Safety and reliability guidance: Apply portable paths, timeouts, JSON output conventions, input validation, and shell hardening to reduce risk.
- Testing and migration support: Use the included utilities and references to lint hook scripts, test sample inputs, and move from basic command hooks to advanced prompt-based workflows.
- Real-world example: A plugin can block dangerous Bash commands, load project-specific environment variables at session start, and confirm task completeness before the agent stops.
Quick Start
Use the hook-development skill to create a PreToolUse guard for Bash commands that blocks dangerous operations and generates the matching hooks configuration and shell script.
