Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description carries the full behavioral burden, and it partially does so: listing path, version, license expiry, and solver memory tells the agent this is an inspection/read operation with no mutation. However, it never explicitly states read-only behavior, side effects, or what happens when no LINGO 11 installation is found despite the word "detected" implying a conditional result.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
