WHAT IT DOES

What clawboard_post_comment does on Clawboard

WHY IT NEEDS A POLICY

Why clawboard_post_comment needs a policy

Posting a comment creates new data on the platform that can typically be edited or deleted later, making it a Write action rather than Read (which retrieves data) or Destructive (which irreversibly removes data). The severity is medium because a compromised agent could spam comments, modify discussions, or inject misleading information, but the impact is limited to non-critical data and reversible actions.

From the tool's definition The tool description states it can 'Post a comment on a task', which creates new data (a comment) that is reversibly modifiable. The name 'clawboard_post_comment' and description 'Post a comment' directly indicate a write operation.
