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

With no annotations at all, the description carries the full burden and does meaningful work: it discloses the pagination default (30 records per page), that credentials come from the OpenAny gateway, and that charges and authorization are gateway-determined. Remaining gaps are behavioral edge cases (failure when no identifier is given, ordering of results) rather than core traits.

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 short sentences, front-loaded with the retrieval action and identifier, followed by pagination and gateway/billing notes. No filler, though the gateway-credentials sentence is somewhat boilerplate across this provider's tools.

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 small read-only lookup with no output schema and no annotations, the description covers what is retrieved, how the enterprise is addressed, page size, and credential/cost handling. The one material omission is that it never says an identifier argument is required in practice despite the schema marking none as required.

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 the baseline is 3, but the description adds real meaning by framing id and tyshxydm as alternative enterprise identifiers rather than two independent filters — a relationship the schema does not state. It also surfaces page size context that pageNo in the schema does not describe.

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 clear verb and resource ('Retrieve administrative penalty records for an enterprise') plus the key used to look it up, which is much more specific than the name/title alone. It does not differentiate itself from nearby siblings in the same family, such as the serious-illegal or abnormal-operation enterprise endpoints, so a 4 rather than a 5.

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 implied by the identifier guidance ('using its enterprise ID or unified social credit code'), but there is no explicit when-to-use or when-not-to-use node, and no statement about which identifier is mandatory even though the schema declares zero required parameters. An agent must infer that at least one of id/tyshxydm must be supplied.

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