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

With no annotations, the description carries the full behavioral burden and does so thoroughly: it discloses that the provider offers no independent entity identity, freshness, completeness, ownership, compliance or safety certification; that results are first-page-only with at most 5 rows; that empty results are not safety findings; that total count is omitted; and that calls cost 0.011 USDC apiece.

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 purpose is front-loaded and the caveats are information-dense, but the text repeats itself: the opening disclaimer and the closing 'No completeness or safety guarantee' duplicate the same idea, and 'One selected Chinese company data tool call' is vague filler.

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 an opaque data-retrieval tool with no output schema and no annotations, the description supplies the essential operating constraints: cost, pagination limits, row cap, empty-result interpretation, and where to find the required company_id. It leaves return fields unspecified, but the provider limitations are sufficiently disclosed that an agent can invoke it responsibly.

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 0% and the single parameter is an opaque nested 'arguments' object. The description partially compensates by instructing the agent to pass arguments matching get_cn_data_tool_schema("v3_sina") and by naming company_id as a field sourced from cn_data_v3_company_detail, but it does not document the expected argument structure or syntax.

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 Chinese sentence clearly states the tool queries enterprise/institution Weibo information, giving a specific verb and resource. It distinguishes itself from company_detail by telling the agent to source company_id from that sibling, but it does not explicitly contrast itself with other media or news siblings.

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?

It supplies a concrete prerequisite (use company_id from cn_data_v3_company_detail) and usage limits (provider first page only, at most 5 rows, no pagination input, additional pages require separate requests). It lacks explicit when-not-to-use guidance or direct sibling alternatives, but the operational context is clear.

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