Use when Codex needs to inspect the GitHub pull request for the current branch, extract AI review findings from CodeRabbit or greptile-apps, read failed checks, MegaLinter warnings, or failed test signals from the PR page, and then verify which findings should be fixed in the local codebase. Trigger explicitly with $gframework-pr-review or with prompts such as "look at the current PR", "extract CodeRabbit comments", "extract Greptile comments", or "check Failed Tests on the PR".
