github_review_commit · Promethean OS MCP: Risk & Policy

WHAT IT DOES

What github_review_commit does on Promethean OS MCP

AI agents use github_review_commit to create or update resources in Promethean OS MCP — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Promethean OS MCP environment.

WHY IT NEEDS A POLICY

Why github_review_commit needs a policy

This tool writes/creates git commits, which modifies repository history reversibly. It does not delete data (would be Destructive), execute arbitrary code (would be Execute), or move money (would be Financial). While commits can be modified or reverted in git workflows, the direct action is to create/write commits.

From the tool's definition Tool description states "Create a git commit" with options to "stage specific paths" or use "--all" flag. Creating commits is a reversible write operation that modifies the git repository state.
