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

With no annotations, the description carries the full burden and does substantial work: it discloses cost (0.011000 USDC per call), a hard truncation to the first page of up to 5 rows, and that results do not attest entity identity or completeness. It is slightly muddled because "no pagination input" sits awkwardly beside "additional pages require separate requests," and the completeness disclaimer is repeated.

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?

Purpose is front-loaded, which is good, but the text is choppy and repetitive — pagination limits are stated twice and the no-completeness/no-identity caveat twice. The price is written with excessive precision (0.011000) and several sentences could be merged without losing information.

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 and no annotations, the description supplies the key operational facts an agent needs: dependency on company_detail, row cap, no paging, per-call cost, and reliability caveats. Return-value structure is not described, but the description does indicate what the rows represent.

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 0% and the single nested 'arguments' object is opaque (additionalProperties: true), so the description must compensate. It does name the required value (company_id from cn_data_v3_company_detail) and redirects to get_cn_data_tool_schema for the full argument shape, but leaves the remaining argument fields unexplained.

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 the resource precisely — recorded software copyrights — which distinguishes it from sibling tools covering patents, trademarks, and standards. The verb is implied rather than stated (it reads as a noun phrase), but an agent can still tell what data class this returns.

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?

Gives a clear prerequisite — company_id from cn_data_v3_company_detail — and points to get_cn_data_tool_schema("v3_software_list") for argument shape, which establishes the call context. It offers no exclusions or comparison against alternative software/IP tools, so it falls short of a 5.

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