WHAT IT DOES

WHY IT NEEDS A POLICY

Why reopen_pull_request needs a policy

This tool reverses a declined state on a pull request, transitioning it back to an open state. This is a reversible write/state-change operation — it modifies the status of an existing resource but does not delete, execute code, or involve financial transactions. Misuse could cause confusion in code review workflows but has limited blast radius.

reopen_pull_request Rate-limited
