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

With no annotations provided, the description carries the full burden, and it delivers extensively: no automatic paging, one bounded GET, local truncation at 100 rows and 256 KiB, oversized records refused, numeric strings preserved, status sample values 0 and 1, and sort/order effects on observed ordering. It also discloses that other declared filters are forwarded as supplied without implied effectiveness, which is transparent about measured limitations.

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 information-dense and front-loaded with purpose, but it is written as a run-on block with repetition: 'no automatic paging' and 'Does not auto-fetch continuation pages' say the same thing twice. Some phrasing is cryptic, such as 'Two pages of two matched four rows,' and the lack of structure makes key caveats harder to parse. It earns a middle score because every sentence carries some useful information, but the organization is poor.

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?

Given no output schema, no annotations, and seven parameters, the description is unusually thorough: it covers request boundaries, local limits, truncation reporting, field preservation, route-specific verification limits, and effectiveness caveats. It does not enumerate output fields or fully specify all parameter value formats, so it is not perfect, but it provides enough behavioral context for an agent to invoke the tool and interpret results with reasonable confidence.

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%, so the description must compensate for the schema's lack of meaning. It explains the required inputs (player, role, limit), enforces limit 1-100, gives observed status values, and notes how sort/order affected ordering. It also clarifies that declared filters are forwarded as supplied but their effectiveness is not guaranteed. It does not fully define every parameter like offset or exact role values, but it adds substantial semantic value beyond raw schema fields.

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 opens with a specific verb and resource: 'Read public SPSP delegation rental records for an explicit player and borrower/lender role.' It also explicitly distinguishes the tool from card-worker rentals, which helps disambiguate it from other rental/delegation endpoints in the sibling list.

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 provides clear context for when to use the tool: it applies to SPSP token delegation rentals, requires explicit player and role, and explicitly states what it is not ('not card-worker rentals'). It also notes measured caveats such as counterparty partial matching being verified only on the player route, which helps set expectations. However, it does not explicitly name alternative sibling tools or give a direct when-not-to-use statement.

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