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

Annotations already declare readOnlyHint, idempotentHint, destructiveHint=false, and openWorldHint=false, so the safety profile is covered. The description adds useful context by saying the operation is authenticated and that it returns payment/execution/delivery state, but it does not cover pagination, permission scope, or how the limit parameter behaves.

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 a single front-loaded sentence with no filler. It states the operation, the authenticated scope, and the relevant order state categories without wasting words.

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?

The output schema can carry return-value details, and annotations cover safety traits, so the description does not need to explain those. However, it omits how role and limit shape results, and it does not route the agent away from sibling trade tools, leaving the definition only minimally complete for a simple optional-parameter list operation.

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 only 50%, and the description adds no parameter meaning. The role parameter has a brief schema description, but limit has only default/min/max and no semantic explanation, and the tool description does not compensate for that gap. This is below the baseline 3 for well-covered schemas.

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 uses a specific verb ('Read') and resource ('authenticated Trade orders') and adds the returned state dimensions. It clearly indicates this is a read operation for the caller's own orders, though it does not explicitly name sibling tools like nexus_trade_list_offers or nexus_trade_create_order.

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 alternatives, and no exclusions. An agent can infer that 'my orders' means authenticated user orders, but the description never states when to choose this over list_offers or create_order, nor how role=buyer/seller/all affects usage.

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