 | `preToolUse` | Before the agent uses any tool (e.g., `bash`, `edit`) | **Approve or deny** tool executions, block dangerous commands, enforce security policies |

 Hook event names can be written in **camelCase** (e.g., `preToolUse`) or **PascalCase** (e.g., `PreToolUse`). Both are accepted, making hook configuration files compatible across GitHub Copilot CLI, VS Code, and Claude Code without modification. Hooks also support Claude Code's nested `matcher`/`hooks` structure alongside the standard flat format.
 
+### Plugin Hooks Environment Variables
+
+When hooks are defined inside a **plugin**, the hook scripts receive two additional environment variables automatically:
+
+| Variable | Description |
+|----------|-------------|
+| `CLAUDE_PROJECT_DIR` | The path to the current project (working) directory |
+| `CLAUDE_PLUGIN_DATA` | The path to a persistent data directory scoped to the plugin |
+
+You can also use these as **template variables** directly in the `bash` or `powershell` fields of your `hooks.json` configuration:
+
+```json
+{
+  "version": 1,
+  "hooks": {
+    "sessionStart": [
+      {
+        "type": "command",
+        "bash": "{{plugin_data_dir}}/scripts/init.sh --project {{project_dir}}",
+        "timeoutSec": 10
+      }
+    ]
+  }
+}
+```
+
+This makes it straightforward to write plugin hooks that are portable across machines and projects without hardcoding paths.
+
 ### Event Configuration
 
 Each hook entry supports these fields:
