description: This rule flags GitHub audit log events where deletion actions occur for Codespaces, environments, projects, or repositories (codespaces.destroy, environment.delete, project.delete, repo.destroy). Deletions can indicate destructive impact such as removing resources or disrupting workflows, so monitoring them helps detect unauthorized or risky changes. It relies on GitHub product audit log records that capture the specific action names for these resource types.
