Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations provided, the description carries the full behavioral disclosure burden. It does add useful behavioral context beyond a bare statement — it reveals the optional hash-computation behavior and the duplicate-detection intent, and 'Inventaria' implies a non-destructive cataloging operation. However, it does not explicitly state whether the tool has side effects, what its output/return looks like, or what scope of assets it scans.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
