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

With no annotations provided, the description carries the full behavioral burden. It hints at conditional output ('once paid, the delivery') but says nothing about permissions, whether the caller must be the buyer or seller, error behavior for unknown order ids, or what happens before payment is made.

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 single sentence is short and front-loaded, which is good, but it is under-specified rather than economical and the comma-heavy phrasing is slightly garbled. Brevity here comes at the cost of clarity.

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 one-parameter lookup with no annotations and no output schema, the description should explain the returned fields (status values, delivery details) and the caller's authorization context. It gestures at the return content but leaves the agent guessing on nearly everything needed to call it correctly.

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 order_id is documented nowhere. The description never mentions what identifier must be supplied or its format (order id vs. something else), so it fails to compensate for the schema gap.

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 name get_order plus the phrase 'Order status and, once paid, the delivery' conveys the resource and roughly what the tool returns, but the phrasing is elliptical and never states a clean verb-object purpose. It is distinguishable from siblings like cancel_order and my_orders, but only weakly.

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 when-to-use guidance, no indication of how this differs from sibling tools such as my_orders, fetch, or get_listing, and no prerequisites stated. The reader must infer the intended scenario entirely.

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