Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Without annotations, the description must carry the full behavioral burden. It says it resolves the active project and returns resources and a summary, but doesn't disclose whether it mutates state (it seems read-only), what 'Resources' are, what the summary contains, or the output format. No permissions, rate limits, or side effects are mentioned.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
