rental_offers_by_player

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

With no annotations, the description carries the full burden and provides substantial detail: one GET, no auto-paging, 100-row/256 KiB limits, truncation reporting, oversized-record refusal, numeric-string preservation, filter pass-through caveats, and a status interpretation warning. However, some clauses are cryptic, such as 'Two pages of two matched four rows,' which reduces clarity.

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 a dense, rambling block with redundancy: 'one bounded GET, no automatic paging' is repeated as 'Makes one logical GET request Does not auto-fetch continuation pages.' The cryptic 'Two pages of two matched four rows' reads like test-observation debris rather than useful guidance.

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 tool with no output schema, it gives strong request, limit, and truncation behavior, but it never clearly states the response shape or field list. Optional parameter semantics are incomplete, and the unclear 'Two pages...' clause adds confusion instead of completing the context.

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 0%, so the description must compensate. It adds meaning for player, limit, status, and sort/order ordering, and warns that filters are forwarded without implied effectiveness. However, offset is left unexplained, and accepted values for sort, order, and status are absent.

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 action and target: 'Read public SPSP delegation offers for an explicit player.' It also explicitly distinguishes this from 'card-worker rentals,' which helps separate it from the many rental/delegation sibling 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?

It clearly signals explicit-player lookups and explains the required limit and bounded single-request behavior. It gives a when-not signal ('not card-worker rentals'), but it does not name alternative sibling endpoints or state when a broader rental/offers tool is preferred.

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