# 🪝 Hooks

Hooks enable automated workflows triggered by specific events during GitHub Copilot coding agent sessions, such as session start, session end, user prompts, and tool usage.
### How to Contribute

See [CONTRIBUTING.md](../CONTRIBUTING.md#adding-hooks) for guidelines on how to contribute new hooks, improve existing ones, and share your use cases.

### How to Use Hooks

**What's Included:**
- Each hook is a folder containing a `README.md` file and a `hooks.json` configuration
- Hooks may include helper scripts, utilities, or other bundled assets
- Hooks follow the [GitHub Copilot hooks specification](https://docs.github.com/en/copilot/how-tos/use-copilot-agents/coding-agent/use-hooks)

**To Install:**
- Copy the hook folder to your repository's `.github/hooks/` directory
- Ensure any bundled scripts are executable (`chmod +x script.sh`)
- Commit the hook to your repository's default branch

**To Activate/Use:**
- Hooks automatically execute during Copilot coding agent sessions
- Configure hook events in the `hooks.json` file
- Available events: `sessionStart`, `sessionEnd`, `userPromptSubmitted`, `preToolUse`, `postToolUse`, `errorOccurred`

**When to Use:**
- Automate session logging and audit trails
- Auto-commit changes at session end
- Track usage analytics
- Integrate with external tools and services
- Custom session workflows
