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 it is unusually rich: one logical GET, no auto-paging, 100-row/256 KiB limits, truncation reporting, refusal of oversized records, and warning against inferring filled state from status. It also notes filters are forwarded without implied effectiveness, which is valuable behavioral context.

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 front-loads purpose well, but it becomes dense and somewhat disorganized. It also repeats the no-auto-paging point twice: 'one bounded GET, no automatic paging' and later 'does not auto-fetch continuation pages,' which wastes space.

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 tool with no annotations and no output schema, the description covers request constraints, response truncation, status caveats, and data preservation. It is incomplete on parameter value details for sort/order/offset, but the core invocation requirements are clear enough.

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 explain limit range and gives a caveat about status, and mentions amount ordering, but it does not define sort/order accepted values, offset semantics, or status values. The compensation is partial rather than complete.

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 resource: 'Read public SPSP delegation offers for an explicit player.' It also distinguishes these from rentals by explicitly stating 'These are token delegations, not card-worker rentals,' which helps differentiate it from sibling tools like rental_offers and rentals_by_player.

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 provides clear context for when the tool is appropriate: an explicit player, public offers, with limit requirements and no automatic paging. It gives exclusions, such as not being card-worker rentals, but does not explicitly name alternative sibling tools or state 'use X instead.'

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