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

No annotations are provided, so the description carries the full behavioral burden. It does not state permissions, whether 'verified' means availability-checked, rate limits, failure behavior, or how count/hours affect the result; only the phrase 'free-first' hints at ordering.

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?

Single sentence, front-loaded with the action and result. It contains no padding or wasted words, though it is under-specified rather than efficiently complete.

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, so return values need not be explained. However, with no annotations and 0% schema description coverage across three parameters, the description omits key context: parameter meanings, selection guidance, and behavioral constraints.

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%, and the description explains none of the three parameters. It does not define 'gpu', 'count', or 'hours', nor their default values or units. The word 'GPU' is not enough to disambiguate the required parameter.

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?

States a specific verb and resource ('Return ... GPU offer'), and the qualifier 'cheapest verified free-first' distinguishes it from sibling price, availability, and recommendation tools. It does not name those siblings or fully unpack 'free-first', but the core purpose is clear.

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?

No when-to-use guidance, no alternatives, and no exclusions. An agent cannot tell from the description when to choose this over gpufeed_recommend, gpufeed_compare_providers, or gpufeed_get_availability.

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