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

With no annotations provided, the description carries the behavioral disclosure burden. It does this well by stating that nothing is bought, ordered, or paid, that no quote is guaranteed, that the service is free, and by listing exactly what the tool returns: who receives the details, the consent wording, and how confirmation happens. It could be even more explicit that the tool itself has no side effects, but the existing disclosure is strong.

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 sentences with no wasted words. 'Read first' is an effective front-loaded call to action, and each sentence earns its place by covering purpose, exclusions, and return contents.

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 zero-parameter informational tool with no output schema, the description is largely complete: it explains what the tool does, what it does not do, and what information it returns. The only minor gap is not explicitly stating that invoking this tool has no side effects, but the framing as a description makes that reasonably clear.

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 zero parameters and the schema is empty, so the baseline is 4. The description adds meaningful context about the tool's purpose and return value, which is more than necessary for a parameterless informational tool.

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 the tool's role: it 'states plainly what submit_enquiry does' on Club Grants, which is a specific informational purpose tied to a named resource. It also distinguishes itself from the sibling submit_enquiry by describing rather than performing the action, though it does not position itself against the checker_* siblings.

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?

'Read first' gives a clear contextual cue that this tool should be consulted before using submit_enquiry, and the description clarifies that it is not a submission or purchase. However, it does not explicitly state when not to use it or name alternative tools, so guidance is implied rather than fully specified.

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