WHAT IT DOES

What pull_request_comment_write does on GitHub

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

RISK

Why pull_request_comment_write is rated Medium

This tool modifies pull request review comments, which are data that can be updated or removed. While 'delete' is mentioned in the description, the tool name emphasizes 'write' and the context of PR comments (which are reversible through git history and can be recreated) suggests the primary classification is Write rather than Destructive.

From the tool's definition Tool name 'pull_request_comment_write' and description 'Update or delete pull request review comment' indicate modification of existing pull request comments.
