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

There are no annotations, so the description must carry the behavioral burden. It only says 'Task text discarded,' which is a useful but narrow disclosure. It does not mention return structure of connection methods, external network calls, authentication/rate limits, or any side effects. For a tool with zero annotations, this is insufficient.

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 only two sentences and every sentence is meaningful. It front-loads the core purpose and adds a behavioral note without redundancy or filler, making it efficient.

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?

No annotations, no output schema, but 9 optional parameters. The description gives task examples but doesn't specify which parameter(s) map to which task (weather -> city?, search -> query?, scrape -> url?). Return format could include connection methods in what shape? Not clarified. Therefore, the definition is not complete for reliable use.

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 coverage is 100% with descriptive parameter definitions, so the baseline is 3. The description's phrase 'task text discarded' provides cross-parameter context that parameter values are not persisted. However, with 9 optional parameters and no description of which parameter corresponds to a given task category, the agent still needs richer mapping to use the tool correctly.

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 the tool finds a public pay-per-call tool gateway for specific task categories (weather, search, scrape, voice) and returns connection methods. This is a clear verb+resource, but it does not explicitly distinguish it from sibling tools that also handle weather or search (e.g., weather-hint, web-fetch).

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 description implies when to use the tool (when a public pay-per-call gateway is needed, for tasks like weather, search, scrape, or voice) but provides no explicit 'when not to use' guidance or alternative tool comparisons. The usage context is present but shallow.

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