Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
The description adds substantial behavioral detail beyond the annotations: it stages membership ends for member confirmation, writes nothing until accepted, and is idempotent across repeated sweeps. It also notes that investor relationships still naming the old firm are included, which is useful operational context for a mutation-adjacent sweep.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
