Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations, so the description carries the full behavioral burden. It does disclose the destructive effect (all positions closed, capital returned) and the success/error return, which is genuinely useful, but it says nothing about authorization requirements, reversibility, or what happens to active copies/followers of the fund during deactivation.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
