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

With no annotations, the description must disclose behavioral traits. It states 'Returns connection methods' and 'Task text discarded', which cover output and input handling, but it fails to mention whether the tool makes external network calls, any rate limits, or what 'connection methods' entails. It also introduces a concept ('task text') that doesn't map cleanly to any schema parameter, adding ambiguity rather than transparency.

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 a single sentence, which is concise and front-loaded with the main purpose. However, it sacrifices necessary information for brevity and includes an ambiguous phrase ('Task text discarded') that creates confusion. It's not overly verbose, but it doesn't earn its place fully because key details about usage and parameters are omitted.

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?

For a tool with 9 optional parameters and no output schema, the description is inadequate. It doesn't explain how parameters map to the 'task' or what the agent should pass, nor does it detail the 'connection methods' returned. The absence of prerequisites, examples, or relationship to siblings leaves an agent guessing about correct invocation. Given the tool's meta-purpose, this is a significant gap.

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%, so the baseline is 3, but the description actively confuses parameter semantics. It mentions 'Task text discarded' yet no parameter is named 'task'; the closest is 'query' (described as 'Search text; discarded after the length check'), which differs. The description doesn't clarify which parameter carries the task or how the gateway uses the others, so it detracts from rather than adds to schema meaning.

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 clearly states a verb ('Find') and a resource ('public pay-per-call tool gateway'), and gives example task types (weather, search, scrape, voice). It conveys that the tool returns connection methods. While it doesn't explicitly contrast with siblings, the mention of 'gateway for a task' distinguishes it from the specific single-purpose tools in the sibling list.

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 use when a gateway is needed for a task, but it provides no explicit when-to-use or when-not-to-use guidance relative to the 27 sibling tools. It doesn't say 'use this instead of calling weather-hint directly' or describe scenarios where the gateway is preferred over a direct tool call. The phrase 'Task text discarded' hints at behavior but not selection criteria.

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