Why update_comment is rated Medium
This tool creates or modifies data reversibly (characteristic of Write category). It does not execute code, delete data, move money, or trigger external operations with unpredictable effects. The severity is medium because unauthorized comment updates could alter project communication and records, but changes can be reverted and the blast radius is limited to comment data within a single issue.
From the tool's definition Tool name 'update_comment' and description 'Update an existing comment' — modifies existing data in a reversible manner. Markdown formatting support confirms text content modification.
Attacks that exploit this kind of access

update_comment 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.
The button opens the PolicyLayer dashboard: create your workspace, connect Huly, apply this rule, and every update_comment call is checked against it from then on.
