# Claude Code Hooks Mastery
[Claude Code Hooks](https://docs.anthropic.com/en/docs/claude-code/hooks) - Quickly master how to use Claude Code hooks to add deterministic (or non-deterministic) control over Claude Code's behavior. Plus learn about [Claude Code Sub-Agents](#claude-code-sub-agents), the powerful [Meta-Agent](#the-meta-agent), and [Team-Based Validation](#team-based-validation-system) with agent orchestration.

### 1. UserPromptSubmit Hook
**Fires:** Immediately when user submits a prompt (before Claude processes it)
**Payload:** `prompt` text, `session_id`, timestamp
**Enhanced:** Prompt validation, logging, context injection, security filtering
### 2. PreToolUse Hook
**Fires:** Before any tool execution
**Payload:** `tool_name`, `tool_input` parameters
**Enhanced:** Blocks dangerous coExcerpt of 41,208 characters
