WHAT IT DOES

What issue_comment_write does on GitHub

AI agents use issue_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 issue_comment_write is rated Medium

This tool modifies issue comments reversibly via update operations. While the description mentions deletion capability, the tool name and primary framing emphasize 'write' rather than 'destructive'. Updating comments is a Write operation.

From the tool's definition Tool name is 'issue_comment_write' and description states 'Update or delete issue comment'. The 'write' suffix and 'update' verb indicate a reversible modification operation.

RECOMMENDED RULE

The rule that runs issue_comment_write safely

issue_comment_write Rate-limited

issue_comment_write stays usable, but capped: an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.
