Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description must disclose all behavioral traits. It only says 'Create a plan' which implies mutation-free planning, but it does not mention whether this plan is persisted, what side effects it has, or what the plan contains. The 'hash-bound evidence-tagged' is a behavioral characteristic but is not explained.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
