+# safe-to-test Label Usage Guide
+
+## Quick Overview
+
+The `safe-to-test` label is used to trigger full integration tests for fork PRs (requires secrets).
+
+## For Maintainers
+
+### When to Use
+
+When a fork PR needs to run full integration tests that require secrets (e.g., `OPENAI_API_KEY`).
+
+### Steps
+
+1. **Review PR code** - Confirm the code is safe and contains no malicious behavior
+2. **Add label** - On the PR page, click "Labels" on the right → search for `safe-to-test` → add it
+3. **Wait for tests** - Adding the label automatically triggers the `pull_request_target` event and runs full tests
+
+### ⚠️ Security Notes
+
+- **Only add the label after confirming the code is safe**
+- Once the label is added, the PR code will have access to secrets
+- If suspicious code is found, **remove the label immediately**
+
+## For Contributors
+
+If your fork PR needs full tests:
+
+1. Submit PR (basic tests will run automatically but fail due to missing secrets)
+2. Wait for maintainer code review
+3. After maintainer adds `safe-to-test` label, full tests will run automatically
+4. After tests pass, the failed `pull_request` check will be automatically updated to success, and the PR can be merged
+
+## How It Works
+
+- **`pull_request` event**: Automatically triggered for fork PRs, but cannot access secrets, tests will fail
+- **`pull_request_target` event**: Triggered after adding `safe-to-test` label, can access secrets, runs full tests
+- **Auto-update**: After `pull_request_target` succeeds, it automatically updates the `pull_request` check status to success
+
