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

With no annotations, the description carries the full burden, and it does add some behavioral value: it says the tool returns connection methods and that task text is discarded. However, it does not disclose authentication needs, whether external paid calls are made, rate limits, or other side effects, so transparency is adequate but incomplete.

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 two short sentences with no filler. It front-loads the core purpose and then states the return value and a privacy-relevant behavior, making it optimally sized given that parameter details live in the schema.

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?

The description does not explain how the 9 input parameters relate to the task categories, what a 'connection method' actually looks like, or which parameters to populate for a weather versus search task. With no output schema and many siblings, an agent lacks enough context to invoke this tool 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 100%, and each of the 9 parameters has its own explanation in the schema, so the baseline is 3. The tool description itself adds no parameter-level guidance about how to choose among city, query, feed, etc., but that information already exists in the schema.

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 ('Find') and a concrete resource ('a public pay-per-call tool gateway'), gives task examples, and names the return value ('connection methods'). It is clear enough to distinguish this index-like tool from the direct sibling tools, though it never explicitly contrasts itself with them.

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 phrase 'for a task such as weather, search, scrape, or voice' provides clear context for when an agent should consider this tool. It does not offer exclusions or name alternatives, so it falls short of the ideal, but the usage context is present.

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