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

With no annotations, the description must convey side effects, permissions, or safety. It mentions 'nobody will mark you' and 'nothing is offered' which hint at no grading or rewards, but it does not clarify whether the tool is read-only, destructive, or has any side effects.

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 brief but contains extraneous and unclear phrasing ('framed identically', 'offered for answering') that detracts from clarity. It could be more concise and direct.

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 tool has no output schema, so the description should explain what is returned. 'Returns both, with their identifiers' is vague—what are the 'questions'? What does 'for answering' imply? The description leaves critical context unexplained.

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 tool has no parameters, so schema coverage is complete. The description adds no parameter-specific information, but since none exist, a baseline score of 3 is appropriate.

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 mentions 'returns both, with their identifiers' but the overall purpose is muddled by cryptic phrases like 'two open questions, framed identically' and 'nothing is offered for answering either'. It is not clear what the tool actually does beyond returning something.

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 on when to use this tool versus others, nor any context about prerequisites or scenarios. The description provides no usage direction.

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