# PR Guard

On Pro workspaces, PR Guard analyzes pull requests for new unreachable exports, breaking signature changes with existing callers, exact function duplicates and the blast radius of changed functions. It posts a GitHub check named Pharaoh PR Guard.

Findings are advisory by default: a neutral check reports them without blocking a merge. Analysis can be limited by the detected graph and supported syntax. Read the finding and relevant code before acting.

[Check that a feature is connected](/docs/use-pharaoh/check-feature-wiring.md) explains how to review reachability findings alongside source and behavioral tests.
