Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
The description thoroughly discloses behavioral traits: it 'never rebuilds from source', 'mints a NEW Roblox version pointing at the old build', and lists specific error codes (404, 422, 409) with meanings. Annotations indicate destructiveHint=true and idempotentHint=false, which the description aligns with. It goes above annotations by detailing rate limits, invalid key handling, and the return payload. This is excellent transparency.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
