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

Annotations already declare readOnlyHint, idempotentHint, destructiveHint=false and openWorldHint=false, so safety and repeatability are covered. The phrase 'authenticated customer order' adds a useful scoping detail (results are limited to the caller's own orders, since no customer identifier is accepted), but no auth failure or not-found behavior is described.

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?

One short, front-loaded sentence with no waste. It is efficient, though borderline under-specified for the amount of structure the neighboring tools carry.

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 single-parameter read with a full set of annotations and no output schema, the minimum viable information is present. It still omits what happens on an unknown/unauthorized orderId, which is relevant given the tool is auth-scoped.

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% and the single required parameter orderId is undocumented in both schema and description. The schema supplies format and pattern constraints but not meaning, and the description does not compensate by saying where the ID comes from or that only the owner's order resolves.

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 (Read), resource (order), and cardinality scope (one), which implicitly separates it from orders_list. However, it doesn't name any sibling or clarify how it differs from orders_get_tracking, which also retrieves order-related data.

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 reach for this tool versus orders_list or orders_get_tracking, and no mention of preconditions such as owning the order or having a valid orderId from a prior call. Usage must be inferred entirely from the tool name.

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