get_order_by_id

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

With no annotations, the description carries the full burden. It discloses the return format ('Dict containing the order details or error information'), which is helpful. However, it does not explicitly state that the operation is read-only, mention permissions, or describe error conditions beyond 'error information', limiting transparency.

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?

The description is extremely concise and well-structured with clear Args and Returns sections. Every sentence earns its place, with no redundant information.

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?

Given the tool's simplicity (one parameter, no nested objects, output schema present), the description covers purpose, parameter, and return behavior. However, it could be more complete by explicitly guiding usage relative to the many sibling order-related tools, which is a minor gap.

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. It explains order_id as 'The order ID to search for', adding meaning beyond the schema's bare 'Order Id' title. This adequately describes the parameter for a simple lookup, though it lacks examples or format constraints.

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 description clearly states 'Retrieve a specific order by its ID', which is a specific verb+resource+scope. This distinguishes it from sibling tools like get_all_orders and get_orders_by_customer_name, which operate on different criteria or return multiple 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?

The description implies usage when you have an order ID and need that specific order, but it does not explicitly state when to use it over alternatives. No mention of when not to use or reference to sibling tools, so guidance is only implied.

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