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

readOnlyHint=true already tells the agent this is a safe read. The description adds context about what the response contains (totals, tips, tax, discounts) and the endpoint, which is modest but real added value. It says nothing about error behavior for a missing/invalid id.

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 what is returned, followed by the API path. No filler.

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 tool with readOnlyHint and no output schema, the description covers purpose, returned fields, and endpoint adequately. Minor gap: no note on what happens when the order does not exist.

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?

Only one parameter (order_id) with 0% schema description coverage, so the description must compensate. The '/v1/orders/{id}' path does imply order_id is the order identifier used as a path segment, which is some help, but format/validity of the id is never clarified.

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?

Specific verb+resource ('Get one order') plus an enumeration of the content returned (totals, tips, tax, discounts) and the underlying endpoint. It implicitly distinguishes itself from the many sibling list_* tools (e.g. moego_list_orders) by saying 'one order', but never names an 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: the singular 'one order' plus the path template suggest it is for fetching a single known order rather than listing. There is no explicit statement of when to pick this over moego_list_orders or what prerequisites (a valid order id) are needed.

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