Read-onlyIdempotent

Find canonical model slugs, context limits, and provider prices. Optional provider_slug filters availability, not the provider in bestOffer. bestOffer is selected for 10M input + 2M output tokens; use offer_compare for your workload. Follow pagination.hasMore.

TDQS

A4.4/5.0

Behavior5/5

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

Annotations cover the safety profile (readOnly, idempotent, non-destructive), and the description adds non-obvious behavior: the exact token mix (10M input + 2M output) underlying bestOffer selection and the availability-vs-provider semantics of provider_slug. It also points at pagination.hasMore for continuation, which is behavior the annotations do not convey.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

Three dense sentences, no filler, front-loaded with the primary purpose and followed by the two constraints an agent most needs (bestOffer basis and pagination). Every sentence carries information.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness4/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

An output schema exists, so return values need not be explained, and the description covers the key selection rule and pagination signal. It is slightly thin on the four undocumented query/pagination parameters, which an agent must infer from defaults alone.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 0%, so the schema documents nothing about page, page_size, query, and category_slug. The description compensates only for provider_slug, explaining its filtering semantics, leaving the other four parameters without meaning beyond their names and defaults.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

States a specific verb and resource plus the concrete outputs (canonical model slugs, context limits, provider prices), which immediately distinguishes it from siblings like provider_list or model_detail. An agent can tell what this returns without opening the schema.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines4/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

Routes the agent to a sibling ('use offer_compare for your workload') and clarifies that provider_slug filters availability rather than the bestOffer provider. It lacks an explicit statement of when not to use it or of prerequisites, but the alternative routing is concrete.

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