-## Security Best Practices
-
-**⚠️ IMPORTANT: Never commit API keys directly to your repository! Always use GitHub Actions secrets.**
-
-To securely use your Anthropic API key:
-
-1. Add your API key as a repository secret:
-
-   - Go to your repository's Settings
-   - Navigate to "Secrets and variables" → "Actions"
-   - Click "New repository secret"
-   - Name it `ANTHROPIC_API_KEY`
-   - Paste your API key as the value
-
-2. Reference the secret in your workflow:
-   ```yaml
-   anthropic_api_key: ${{ secrets.ANTHROPIC_API_KEY }}
-   ```
-
-**Never do this:**
-
-```yaml
-# ❌ WRONG - Exposes your API key
-anthropic_api_key: "sk-ant-..."
-```
-
-**Always do this:**
-
-```yaml
-# ✅ CORRECT - Uses GitHub secrets
-anthropic_api_key: ${{ secrets.ANTHROPIC_API_KEY }}
-```
-
-This applies to all sensitive values including API keys, access tokens, and credentials.
-We also recommend that you always use short-lived tokens when possible
