Annotations already provide readOnly, openWorld, idempotent, and non-destructive hints, so the description's additional claim of returning a single sentence adds minimal behavioral insight. However, it does not disclose error behavior or quality criteria.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is a single sentence of 14 words, front-loading the key action and result. No extraneous information is present.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given the presence of an output schema (which likely explains return values) and annotations covering safety, the description is mostly complete for a simple tool. It could mention edge cases (e.g., word not found) but is generally adequate.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
With 0% schema description coverage, the description should explain parameters but does not. While 'word' is self-explanatory, 'useCanonical' is not described at all, leaving the agent guessing about its meaning.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the tool returns a single highest-quality usage example sentence for a word from Wordnik's corpus. It specifies the verb 'Return', the resource 'usage example sentence', and includes a qualifier 'single highest-quality', which distinguishes it from sibling tools like 'examples' that likely return multiple examples.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Does the description explain when to use this tool, when not to, or what alternatives exist?
The description implies usage for obtaining the top example but does not explicitly state when to use this versus alternatives (e.g., 'examples' for multiple). It also omits guidance on the optional 'useCanonical' parameter.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
