WHAT IT DOES

What git_steer_pr_create does on Git Steer

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

WHY IT NEEDS A POLICY

Why git_steer_pr_create needs a policy

Creating a pull request modifies repository state by introducing a new PR object and potentially triggering CI/CD workflows. While reversible (PRs can be closed), the blast radius is high because an AI agent could create malicious PRs targeting security-sensitive repositories, inject code into review pipelines, or flood repositories with spam PRs.

From the tool's definition Tool name 'git_steer_pr_create' and description 'Open a pull request' indicate creation of a new pull request, which creates reversible changes in a repository.
