Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations provided, the description carries the full burden of behavioral disclosure. It states the tool 'discovers' and 'transduces', implying a read/compute operation, but it does not disclose whether this mutates state, whether it requires a pre-existing source_lattice_id, what happens when inputs are missing, or what the output contains. The abstract phrasing leaves the tool's actual behavior opaque.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
