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

With no annotations, the description carries the full behavioral burden. It does disclose the sort order (most recent first), but says nothing about pagination behavior, result size limits, permissions, or what the returned records contain.

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 front-loaded sentence with zero filler; the scoping and ordering facts come first. It is efficient, though its brevity partly reflects missing content rather than disciplined compression.

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 list tool with two undocumented paging parameters, no annotations, and no output schema, the description should cover pagination and result shape. It leaves the agent without guidance on how many orders come back or how to page.

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 description mentions neither limit nor offset. The schema carries defaults and min/max bounds, but the meaning of these paging parameters and how to use them is documented nowhere.

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 and resource (lists... letter orders) and adds useful scope ('this customer's') plus default ordering ('most recent first'). It is distinguishable from get_order (singular fetch) by implication, but never names the sibling or explicitly contrasts with it.

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 gives no when-to-use guidance, no mention of alternatives like get_order for a single order, and no note on when not to use it. Usage is only inferable from the verb 'Lists'.

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