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

Annotations (readOnlyHint=false, openWorldHint=true) are sparse and arguably surprising for what appears to be a data-fetch operation, so the description carries the burden of explaining behavior — and it discloses nothing: no mention of what is returned, whether translation is machine-generated, fallback behavior, or limits. The only hints come from the schema, not the description.

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?

One short sentence, but its brevity reflects under-specification rather than economy — the same title text is repeated with no functional content front-loaded. There is nothing to be concise about because nothing informative is said.

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 four parameters, no output schema, and annotations that do not establish a read-only profile, the description would need to explain the operation and its semantics. It says nothing useful, leaving the agent unable to confidently select or invoke the tool against the many sibling patent-description endpoints.

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 description coverage is 100%, and the schema itself richly documents lang, patentId, patentNumber, and replaceByRelated including precedence rules and limits. Per the high-coverage baseline, 3 applies; the description itself contributes zero additional parameter 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 merely restates the title: 'Patent Intelligence ZY: description Data Translated API.' It names no verb and no operation, so an agent cannot tell from the text whether it fetches, translates, or submits patent descriptions. Only by reading the parameter names (patentId, lang) can one infer it retrieves translated description text, and nothing distinguishes it from the sibling nexscope_data_zy_description_data.

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?

There is no guidance whatsoever on when to call this tool, no prerequisites (e.g., needing a patent ID vs. a publication number), and no mention of the untranslated sibling nexscope_data_zy_description_data or nexscope_patent_description_data_translation. The agent is left to guess between near-identical siblings.

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