Skills are plain text instructions the agent follows, sometimes with scripts. Check the source, prefer repositories with many installs and stars, and read any script it ships.
Install
npx skills add anthropics/claude-plugins-official@hook-developmentRuns in a terminal with Node.js 18 or newer. Add -y to skip the prompts and -g to install for every project instead of this one.
Install for your agent

Start a new session afterwards so the agent picks the skill up. In Claude Code you can also call it directly with /hook-development.
What it does
Hook Development for Claude Code Plugins Overview Hooks are event-driven automation scripts that execute in response to Claude Code events. Use hooks to validate operations, enforce policies, add context, and integrate external tools into workflows. Key capabilities: - Validate tool calls before execution (PreToolUse) - React to tool results (PostToolUse) - Enforce completion standards (Stop, SubagentStop) - Load project context (SessionStart) - Automate workflows across the development lifecycle Hook Types Prompt-Based Hooks (Recommended) Use LLM-driven decision making for context-aware…
