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

With no annotations, the description carries the burden, and it does add useful context: 30 records per page by default and that charges/authorization come from the OpenAny gateway. It does not say whether at least one identifier is required (schema shows zero required params) or what happens if none is supplied, which matters for a lookup tool.

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?

Two short sentences with zero filler, and the core retrieval scope plus identifier options is front-loaded ahead of the pagination and gateway notes. Nothing is wasted, though the second sentence is somewhat tangential to invocation.

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 read-only paginated lookup with no output schema, the description covers pagination and cost/authorization adequately. The key gap is that with zero required parameters it never clarifies whether an identifier is mandatory or which of the two should be preferred when both are available.

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%, so id, pageNo, and tyshxydm are already documented in the schema. The description echoes the two identifier options and the default page size but adds no format, precedence, or fallback detail beyond structured data, so the baseline 3 applies.

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 states a specific verb (retrieve) and a specific resource (registration change records) for an enterprise, identified by ID or unified social credit code. It is clear enough to distinguish from sibling risk tools like enterprisepunishment or enterprisepledge, though it never names those siblings to make the contrast explicit.

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 tells the caller what inputs identify the enterprise but gives no when-to-use or when-not guidance, and does not route to any alternative sibling such as enterprisebaseinfo or enterprisesearch. The agent must infer the use case purely from the tool name and resource description.

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