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

Annotations already declare readOnlyHint=true and destructiveHint=false, so the safety profile is covered. The description adds real value by enumerating the returned payload (status values, delay, items, total, order_url, seller), which matters because there is no output schema. It omits whether 'delay' is a field or a modifier and says nothing about errors for unknown order_ids.

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?

A single sprawling sentence that leads with the return payload rather than the action, and buries the one routing hint ('Same as order_status') at the very end. The status enum list consumes most of the text, pushing the purpose and usage signal out of the front-loaded position.

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-parameter read with no output schema, enumerating return fields is the right instinct and mostly covers the gap. But ambiguity around order_status redundancy and the lack of any failure behavior leave the agent with open questions before calling.

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 100%, with order_id explained as coming from place_order or my_orders and shop explained via find_shops. The description adds nothing beyond that, so baseline 3 applies.

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 identifies the specific resource and enumerates exactly what it returns: status enums, items, total, order_url, seller. It is a noun phrase rather than a verb-led statement, but an agent can still tell it fetches a single order. The closing 'Same as order_status' hints at the closest sibling, though ambiguously.

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 use this versus order_status, my_orders, or quote_order. 'Same as order_status' is the only nod to an alternative and it reads more like a duplication notice than a routing rule, leaving the agent unsure which of the two to call.

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