get_order_state

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

Annotations already declare readOnlyHint=true and openWorldHint=true, so the safety profile is covered. The description adds the content of the response (execution status, filled quantity, average price), which is genuinely useful since there is no output schema, but it says nothing about auth requirements, freshness/real-time behavior, or error cases for an unknown order.

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?

Short and front-loaded, with the purpose stated before the Args block. The Args list duplicates the schema field titles, adding a little redundancy, but the overall text stays tight.

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 two-param read tool with readOnly annotations and no output schema, the definition is mostly sufficient: it names the key returned fields. It falls short only on ID format and the failure case of an invalid or unknown order_id.

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 must compensate, but it does not: 'account_id: Account ID' and 'order_id: Order ID' merely restate the parameter names. No format, expected ID type, or relationship between the two params is given.

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 (Get) and resource (detailed status of a specific order) and enumerates the returned content: execution status, filled quantity, average price. The singular 'specific order' implicitly separates it from the sibling list-tool get_orders.

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?

No when-to-use guidance, no mention of alternatives like get_orders, and no prerequisites (e.g., an existing/open order). Usage is only inferable from the tool name and return fields.

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