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

Annotations already declare readOnlyHint, idempotentHint, non-destructive, and a closed-world profile, so the safety surface is covered. The description adds genuine behavioral context beyond that: it returns prices exactly as printed and deliberately performs no calculation. It does not mention whether the Spanish page yields translated or mirrored prices, which matters given the language parameter.

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?

Two sentences, no filler, with the content inventory first and the scope limitation ('no custom totals') second. The opening colon-fragment ('The pricing page:') is slightly awkward but reads efficiently and every listed item is substantive.

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?

An output schema exists and annotations are rich, so return-value and safety explanations are not needed here. For a one-optional-parameter read tool, the description covers scope, content, and the no-calculation boundary adequately; only the language-parameter behavior is left unaddressed.

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 100% — the single 'language' enum is fully documented in the schema with defaults and the /es/ path. The description adds nothing about the language parameter, so the baseline 3 applies: the schema carries the semantic load.

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 names a specific resource (the pricing page) and enumerates its contents: per-machine washer/dryer prices, typical wash-and-dry cost, vending prices, the Scan to Pay surcharge note, and the commercial/bulk note. It also scopes itself with 'Returns published prices without calculating custom totals.' It is not explicitly differentiated from any named sibling, but among the listed siblings (amenities, hours, machines, payment methods) no other tool plausibly competes for pricing content, so ambiguity is low.

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?

There is no explicit when-to-use or when-not-to-use guidance, nor any named alternative. The clause 'without calculating custom totals' implies a boundary (do not invoke for computed/custom pricing), but it never states the positive trigger condition or what to do instead for custom totals. Usage is inferable rather than guided.

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