get_top_hysa_rates

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

There are no annotations, so the description carries the full burden. It does disclose that the output includes freshness and attribution metadata, which gives some behavioral context beyond a simple 'return rates'. However, it omits details like whether the operation is purely read-only, how 'top' is determined, or any response shape.

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?

One sentence, front-loaded with the core action and resource, with no filler. Every word adds meaning, and the sentence is appropriately sized for the described tool.

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?

Given no annotations, no output schema, and multiple sibling tools, the description is too sparse. It does not explain the output structure, the meaning of 'top', the data source, or how this tool differs from get_top_rates, so an agent lacks enough context to invoke it correctly and confidently.

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 does not mention the 'limit' parameter at all. The schema's minimum/maximum constraints help, but the description fails to explain that limit controls the number of rates returned or how it interacts with the output.

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 states a specific action and resource: return top high-yield savings rates, with explicit output metadata (freshness and attribution). It is clear, but it does not distinguish itself from sibling tool get_top_rates, which may represent the general rates tool.

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 guidance about when to use this tool versus alternatives such as get_top_rates or get_reality_score. No context, exclusions, or conditional conditions are provided; the agent is left to infer the appropriate use case entirely.

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