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

Annotations already declare readOnlyHint=true and the description is consistent with a safe read. It adds the useful pagination fact ('one page'), which signals the caller must iterate, but says nothing about ordering, default result size beyond the schema, or what a page contains — with annotations covering safety, that is an acceptable but thin contribution.

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 paging behavior and no filler. The trailing raw HTTP path is mildly redundant with the tool identity rather than earning space, which keeps it from a 5.

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 seven parameters, no output schema, and a read-only annotation, the definition is minimal but workable because the schema is fully documented. It stops short of describing the response shape or how to sequence paging against pageIndex, which an agent needs when a result set spans multiple pages.

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 all seven parameters (id, limit, fields, wField/wValue/wOperator, pageIndex) are already documented in the schema. The description adds no extra semantics beyond the implied pagination, 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 title and tool name establish that this lists an account's orders, but the description body only says 'Read one page of related records' without naming the resource. The GET path 'GET /v1/accounts/{id}/orders' implicitly identifies the resource, so an agent can infer the purpose, but it must decode a URL rather than read a stated verb+resource.

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?

There is no guidance on when to use this versus siblings such as servicemonster_list_orders (global order list) or servicemonster_get_account / servicemonster_get_account_profile. The description gives no conditions, prerequisites, or exclusions to route the agent correctly.

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