rentals_by_player

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

With no annotations, the description carries full burden and is unusually candid: it discloses that paging/sort are not independently established, that the call returns one bounded response without auto-pagination, that other filters are forwarded without implied effectiveness, and that rows are locally limited to 100 and 256 KiB with truncation reporting and refusal of oversized records.

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 front-loaded with purpose and covers necessary caveats, but it is repetitive: 'Returns one bounded response without automatic continuation' is essentially restated by 'Makes one logical GET request and does not auto-fetch continuation pages,' and some sentences like 'Required inputs reflect tool policy...' add little concrete value.

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 read endpoint with no annotations and no output schema, the description supplies substantial context: response bounding, local truncation limits, text/metadata truncation reporting, refusal behavior, and wire-string preservation for key fields. It stops short of 5 because there is no explicit description of the overall return shape beyond these fields.

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. It does add meaning for the limit (1-100), required inputs, and warns that other declared filters are forwarded as supplied without implied effectiveness. However, it does not define accepted values or behavior for sort, order, or offset, leaving a clear gap.

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 legacy SPSP delegation rental records for an explicit player and limit of 1 to 100.' It also distinguishes the domain by stating these are token delegation rentals, not worker-card rentals, which separates it from the many sibling rental tools.

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 clear context by scoping use to legacy SPSP delegation rentals and explicitly excluding worker-card rentals. It does not name a sibling alternative (such as rentals_v3_by_player) or provide a when-not condition, so it stops short of a 5.

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