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

Annotations already declare readOnlyHint=true, openWorldHint=true and destructiveHint=false, so the safety profile is covered. The description adds that the response includes line items and exposes the underlying REST route, but says nothing about not-found behavior, permissions, or payload shape beyond 'lines'.

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 verb+resource and the key 'with its lines' detail. Nothing is redundant and no padding is present.

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 simple one-parameter lookup with annotations covering safety, the description is close to sufficient, and 'with its lines' partially compensates for the missing output schema. Still, with no output schema the agent gets no sense of the response structure or error behavior.

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?

There is a single parameter at 0% schema description coverage, so the schema gives no help. The description's 'by id' hints that sales_order_id identifies the order, but it adds no constraints (positive integer, source of the id, what happens with an unknown id).

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 and resource ('Get a sales order') and adds meaningful scope: retrieval by id, including the order's lines. It implicitly contrasts with list-oriented siblings like laudus_list_sales_orders ('by id' = single record), but never names that alternative explicitly.

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 tool to call when it has a specific sales order id. There is no explicit statement of when to prefer it over laudus_list_sales_orders or laudus_pending_sales_orders, and no prerequisites or failure conditions are given.

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