WHAT IT DOES

What create_pr_review does on Forgejo

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

RISK

Why create_pr_review is rated Medium

Creating a PR review is a reversible write operation—it adds metadata/comments to a pull request without deleting data or executing arbitrary code. The impact is limited to repository documentation/communication artifacts. Severity is medium because while reviews influence development workflow and can block merges, they don't directly execute code, delete data, or move funds.

From the tool's definition Tool description explicitly states 'Create a review on a pull request', which is a create operation that modifies PR state by adding review feedback.
