PR Reviewer Guide 🔍

Here are some key observations to aid the review process:

⏱️ Estimated effort to review: 2 🔵🔵⚪⚪⚪

🧪 No relevant tests

🔒 No security concerns identified

⚡ Recommended focus areas for review Test Coverage The workflow only runs doc tests and unit tests with --lib flag, which might miss integration tests or binary tests. Consider adding a step to run all tests with cargo test --workspace without flags. - name: Run doc and unit tests run: cargo test --doc --workspace && cargo test --lib --workspace Missing Format Check The job name mentions "Format" but there's no step that actually runs cargo fmt --check to verify code formatting. name: Format, Tests & Coverage

PR Code Suggestions ✨

Explore these optional code suggestions:

Category	Suggestion	Impact
Security	Use standard runners for security Consider using a standard GitHub-hosted runner instead of a self-hosted runner for better security. Self-hosted runners can be vulnerable to security risks when running code from external contributors in pull requests. .github/workflows/pr_checks_rs.yaml [19] -runs-on: self-hosted +runs-on: ubuntu-latest Apply this suggestion Suggestion importance[1-10]: 8 __ Why: Using self-hosted runners for PR checks can pose significant security risks, especially when processing code from external contributors. GitHub-hosted runners provide an isolated, secure environment that automatically resets after each job.	Medium
General	Split tests for better visibility Split the test commands into separate steps for better visibility of failures in the GitHub Actions UI. This makes it easier to identify which specific test type failed. .github/workflows/pr_checks_rs.yaml [41-42] -- name: Run doc and unit tests - run: cargo test --doc --workspace && cargo test --lib --workspace +- name: Run documentation tests + run: cargo test --doc --workspace + +- name: Run unit tests + run: cargo test --lib --workspace Apply this suggestion Suggestion importance[1-10]: 6 __ Why: Splitting the test commands into separate steps improves workflow readability and debugging. When tests fail, it becomes immediately clear which type of test (documentation or unit) is failing, making troubleshooting more efficient.	Low

CI Feedback 🧐

Action: Tests

Failed stage: [❌]

Failure summary: The action failed because it was waiting for a runner to pick up the job but no runner was available or assigned. This is an infrastructure issue rather than a code problem. The job was defined in the workflow file pr_checks_rs.yaml but couldn't start execution.
