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

With no annotations present, the description carries the load and does add real behavior: results are paginated at 30 per page by default, credentials come from the caller's OpenAny gateway, and charges/authorization are gateway-determined. It does not explain what happens if both id and tyshxydm are supplied, or what an empty/unauthorized response looks like, but the billing and pagination disclosure is substantive.

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?

Three sentences with the retrieval purpose front-loaded, then pagination, then gateway/billing caveats. No redundancy, though the closing gateway sentence is generic boilerplate that could be tightened.

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 three-parameter, no-annotation, no-output-schema read tool, the description covers inputs, pagination, and cost/authorization context, which is close to sufficient. The main remaining gap is any hint about what a software copyright record contains, since there is no output schema to describe it.

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 id, pageNo, and tyshxydm already carry their own descriptions. The description adds the useful either/or framing between enterprise ID and credit code, but does not say whether both may be combined, which takes precedence, or what the per-page cap is beyond the default. 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 ('Retrieve') and resource ('software copyright records') scoped to one enterprise, and names the two acceptable enterprise identifiers. An agent can tell it apart from generic sibling tools like enterprisebaseinfo or enterprisepatent, but it never names a close alternative (e.g. qcc_post_ipr_get_software_copyright_info) that also returns software copyright 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?

Usage is only implied: the tool is for looking up software copyrights of a known enterprise. There is no explicit when-to-use, no when-not, and no routing advice despite many overlapping sibling tools in this namespace. An agent must infer the selection rule.

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