Does the description clearly state what the tool does and how it differs from similar tools?
The description states a specific verb ('get'), a precise resource (word overview), and enumerates the exact contents per synset (synset_id, label, definition, lexfile, ontological_types, synonyms, hypernym). It also clarifies a key scoping rule (only synsets where the word itself has a sense count), which makes the tool's purpose distinct from simply listing synsets.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
