-- Checking out the SDK at the specified version
+- Checking out the extensions repository at the specified version
 - Setting up Python and dependencies
-- Running the PR review agent
+- Running the PR review agent (from extensions repo)
 - Uploading logs as artifacts

 The workflow uses `pull_request_target` so the code review agent can work properly for PRs from forks. Only users with write access can trigger reviews via labels or reviewer requests.
 
 <Warning>
 **Potential Risk**: A malicious contributor could submit a PR from a fork containing code designed to exfiltrate your `LLM_API_KEY` when the review agent analyzes their code.
 
 To mitigate this, the PR review workflow passes API keys as [SDK secrets](/sdk/guides/secrets) rather than environment variables, which prevents the agent from directly accessing these credentials during code execution.
