rental_bids_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 delivers extensively: single bounded GET, no auto-paging, observed ordering quirks, numeric string preservation, status-field caveats, local 100-row/256 KiB truncation with reporting, and refusal of oversized records. This far exceeds typical behavioral disclosure.

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 content is valuable but poorly organized: the no-auto-paging behavior is stated twice ("no automatic paging" and "Does not auto-fetch continuation pages"), which violates the every-sentence-earns-its-place rule. There are also grammar and punctuation issues ("Require limit 1-100", "Makes one logical GET request Does not auto-fetch", "The data list are", and the cryptic "Two pages of two matched four rows"). A single dense paragraph without structure hurts scannability.

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 there is no output schema and no annotations, the description covers the high-risk operational aspects well: paging behavior, filter effectiveness, status semantics, truncation reporting, and oversized-record handling. It does not explicitly describe the overall return shape or error/success codes, but the field-preservation and truncation notes bring it close to complete for a read-only endpoint.

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: it reinforces limit bounds (1-100), explains the status semantics (do not infer filled state), and broadly warns that extra filters like sort/order/offset are forwarded without guaranteed effectiveness. It does not individually document every parameter's exact meaning, but it covers the critical ones and manages expectations for the rest.

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 first sentence states a specific verb+resource+scope: "Read public SPSP delegation bids for an explicit player." It also disambiguates from confusing domains with "These are token delegations, not card-worker rentals," which separates 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?

The description gives clear context: this reads only public bids for an explicit player, requires limit 1-100, and performs a single bounded GET with no paging. It also warns that "Other declared filters are forwarded as supplied; their effectiveness is not implied by the schema" and cautions against inferring filled state from status. It stops short of explicitly naming a sibling alternative, but the "not card-worker rentals" exclusion is strong contextual direction.

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