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

With no annotations provided, the description carries the full burden of behavioral disclosure, and it excels: it reveals single-GET behavior, no auto-fetching of continuation pages, local 100-row/256 KiB limits with truncation reporting, refusal of oversized records, price filter quirks (rejects decimals, forwards without rescaling), and measured/unmeasured combination behavior. This is far beyond the structured schema.

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 the core purpose, but the middle is a rambling sequence of measurement notes and caveats that would be clearer organized into sections like 'Behavior', 'Limits', and 'Known Quirks'. Statements such as 'Two pages of two transaction IDs matched the first four rows' are confusing without context and detract from the actionable 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 9 parameters, no output schema, and no annotations, the description covers a remarkable amount: request behavior, truncation, type handling, and tested filters. Still, it omits the response format entirely and leaves several parameters (offset, sort, order, minPrice) undefined in any practical sense, so an agent would still face uncertainty when constructing a full request.

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, and it partially does: it details limit range, price filter behavior (integer accepted, decimal rejected), quantity bounds, and the combined player/sort/price/quantity probe. However, it does not give per-parameter meaning for offset, sort values, or minPrice/maxPrice semantics, and the catch-all note that other filters are forwarded without implied effectiveness is a meta-caveat rather than concrete guidance.

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 opening sentence clearly states the tool reads public SPSP delegation rental offers with a limit of 1-100, which specifies a verb, resource, and constraint. The later clarification that these are token delegation offers/bids, not card-worker rentals, helps distinguish from similar rental tools, though no sibling tool is explicitly named.

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 establishes clear context: this is for public SPSP delegation rental offers, with the explicit caveat that it is not for card-worker rentals. However, it never states when to prefer this tool over siblings like rental_offers_by_player or rental_offers_lowest_price, and the 'when-not' is only implied rather than naming alternatives.

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