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

Annotations already declare readOnlyHint, idempotentHint and destructiveHint=false, so the safety profile is covered. The description adds two things the annotations do not: the result ordering ('newest first') and an authentication requirement ('Requires an API key'). It omits pagination/default-limit behavior, which keeps it from a 5.

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, front-loaded with the resource and scope, no filler or repetition of the title. Every clause carries 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 three undocumented parameters, no output schema, and no explanation of what a returned order looks like or how 'limit' paginates, the description leaves significant gaps for a filtering tool. Only the auth and sorting facts are supplied.

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%, so the description carries the full burden, yet it only partially explains the 'role' parameter ('buyer, seller or both') and says nothing about 'limit' or the eight-value 'status' filter. Two of three parameters remain semantically opaque.

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+resource ('list ... orders') with the scope qualifier 'as buyer, seller or both' and an ordering guarantee ('newest first'). This is clearly separable from the singular get_order sibling, though it never names an alternative explicitly, which keeps it just short of 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 only implied: an agent can infer this is the bulk-retrieval counterpart to get_order, and 'as buyer, seller or both' hints at the role parameter's purpose. There is no explicit when-to-use rule, no when-not-to-use, and no mention of siblings, so it stays at minimum-viable.

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