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

Annotations already declare readOnlyHint=true and openWorldHint=false, so the safety profile is covered. The description adds what the payload contains (license scope, citation string, download URLs), which is useful behavioral context, but says nothing about format, completeness, or whether the addresses are stable.

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?

It is a single sentence fragment with no verb, which reads as a bullet list of payload items rather than a front-loaded purpose statement. Every element is relevant, but the lack of a leading verb hurts scannability.

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?

With no output schema, the description must explain the return values, and it does so adequately: license terms, citation text, and download addresses. It stops short of describing the shape of the response or how an agent should use the returned citation, which is a minor gap for a zero-param informational tool.

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?

The tool takes zero parameters, so the baseline of 4 applies. The description does not introduce any parameter-related confusion, and the schema coverage is moot with an empty object.

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 names the specific content returned (license terms, citation text, CSV/JSON download addresses) and, with the title, makes clear this is a citation/reuse resource rather than a word-list retrieval tool, distinguishing it from siblings like get_word_list. It lacks an explicit verb phrase, but the resource is unambiguous.

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?

Usage is implied by the title 'How to cite and reuse the word lists' — an agent can infer it should call this when attribution or download links are needed. There is no explicit when-not or reference to sibling tools, and no statement about how it complements list_word_lists/get_word_list.

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