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

Annotations already declare readOnlyHint=true, idempotentHint=true, destructiveHint=false, and openWorldHint=false, so safety and mutability are fully covered. The description adds nothing beyond that — no pagination, filtering behavior, permission requirements, or result shape — so it earns only the minimum for not contradicting the annotations.

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 literally repeats the same sentence twice ('GET /api/leases/:id/payment-requests. GET /api/leases/:id/payment-requests.'), wasting half its length. What remains is a path dump plus a boilerplate operation-ID note, with no front-loaded explanation of what a payment request is.

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?

There is no output schema, and the description does not describe what a payment request contains or how results are returned, so the agent has no model of the response. With zero parameter documentation and an unexplained free-form query object, the definition is not sufficient to call the tool confidently without first invoking describe_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 0% and the description documents neither the required `id` (implicitly the lease id from the path) nor the free-form `query` object. The path token ':id' gives a faint hint about the required parameter, but nothing about what query options are accepted, which is a real gap for a 2-parameter tool with a nested free-form object.

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 is a verbatim copy of the title, itself just a raw HTTP path. It does convey that this retrieves payment requests scoped to a lease, but it restates the name/title rather than describing the operation in human terms, and it offers no differentiation from the hundreds of other lease-subresource GET siblings.

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 a sibling like get_leases_by_id_payments or the accounting lease payment-schedule endpoints. The only routing hint is that describe_operation 'provides native request schemas,' which is a schema-fetch pointer, not usage guidance.

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