WHAT IT DOES

What add_approval_request_comment does on Huly

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

RISK

Why add_approval_request_comment is rated Medium

The tool performs a create operation that adds a comment to an approval request, which is a reversible modification. This is characteristic of Write category tools. Severity is medium because while comments are generally low-risk, they modify business-critical approval workflows and could be used to spam, mislead, or obstruct approval processes if misused by an agent.

From the tool's definition Tool description states 'Add a plain markdown comment to an approval Request' — this creates new data (a comment) that modifies the approval request record.
