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

Annotations already declare readOnlyHint=true, so safety is covered; the description usefully adds the fixed 25-per-page size and the response fields. It stops short of saying how to detect the last page or that total page count is returned (which the schema mentions), and gives no sense of result volume or ordering.

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?

Three tight sentences with the resource and page size front-loaded before the paging rule. The trailing 'GET /baskets.api' is mildly extraneous for an agent that doesn't call HTTP directly, but the rest earns its space.

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, read-only list tool with no output schema, the description supplies what the schema can't: the page size and the shape of each record. What remains missing (sort order, filtering capability) is minor at this complexity level.

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 coverage is 100%, and the schema already explains 1-based paging, the default of 1, and the total-pages reply. The description repeats the increment-by-one rule without adding anything the schema lacks, so the 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?

Specific verb+resource ('List all rental orders') with concrete qualifiers: page size of 25, the fields returned (status, customer, dates), and the underlying endpoint. It is clearly distinct from get_order and the write-oriented order siblings, though it doesn't explicitly name those alternatives.

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?

'List all' plus pagination instructions implies the broad-enumeration use case, and an agent can infer get_order is the single-record counterpart. However, there is no explicit when-to-use/when-not statement or named alternative (e.g., filtering by customer or status) anywhere in the text.

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