Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

No annotations are provided, so the description carries full behavioral burden. It doesn't disclose whether at least one search parameter is required, how multiple parameters combine (AND/OR), rate limits, or the response format. These gaps matter for a 7-param tool with all-optional parameters.

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?

A single, well-structured sentence that front-loads the verb and enumerates the search dimensions efficiently. No wasted words.

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?

For a 7-parameter, all-optional tool with no annotations and no output schema, the description is too thin. It should explain parameter combination behavior, whether at least one criterion is needed, and what the results contain. Key behavioral context is missing.

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?

Schema coverage is 100%, so parameter descriptions are already fully documented in the schema. The description lists the same modes (rhyme, sound, spelling, meaning, adjective/noun) but adds no syntax, format, or combination details beyond what the schema provides. Baseline 3 is appropriate.

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?

States a specific verb ('Find') and resource ('words') and enumerates the search modes (meaning, sound, spelling, rhyme, adjective/noun relationship). This differentiates it from most siblings, though 'datamuse_suggestions' is a related sibling that isn't addressed. The purpose is clear.

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 by listing the search modes, but never states when to use this tool versus alternatives like datamuse_suggestions or dictionary_lookup. No explicit when/when-not guidance is given; the agent must infer that this is a general word-finding tool.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
