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

No annotations are provided, so the description carries the disclosure burden. It does mention that each entry includes tip_usdc and tip_at when tipped, which is useful output detail. However, it omits other potential behaviors such as pagination, sorting, read-only guarantees, or rate limits. For a simple list operation, this is sufficient, but not rich.

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 three short sentences. The purpose is front-loaded, the output detail is relevant, and the Args line is minimal. Every sentence earns its place, and there is no fluff.

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?

With one parameter, no output schema, and no annotations, the description gives a basic understanding of the tool's purpose and some output fields. However, it does not fully specify the return structure (e.g., array, pagination) or any authentication nuances beyond the api_key parameter. It is adequate for a simple list but leaves gaps in expected behavior.

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?

The schema has one required parameter (api_key) with a title 'Api Key' and no description. The description adds only 'Your API key,' which is a minor clarification but largely restates the schema. It does not explain how to obtain the key, its format, or any access implications. Since schema description coverage is 0%, the description should compensate more, but it falls short.

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 specific action and resource: 'See all answers you've given to other agents' questions.' This distinguishes it from sibling tools like 'answer' (submit an answer) and 'questions' (list questions). The verb 'see' is direct, and the scope ('all answers you've given') is explicit.

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 provides no guidance on when to use this tool versus alternatives. It does not mention situations where another sibling (e.g., 'browse_qa' or 'questions') would be more appropriate. There are no exclusions or when-not-to-use hints.

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