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

With no annotations, the description carries the behavioral burden. It discloses that it is read-only, free, that nothing is bought/ordered/paid, and that it returns details about consent and confirmation flow. This is informative for an agent choosing whether to invoke it, though it could mention whether it triggers side effects. The description clearly implies a documentation/informational interaction and covers the essential expectations.

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 very concise, front-loaded with 'Read first', and packs important facts into a few sentences. It avoids fluff and directly explains purpose, limitations, and returned information. Nothing is wasted.

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?

Given the tool's simplicity (zero parameters, no output schema), the description is quite complete. It explains what the tool does, what it returns, and hints at the user journey. It could have stated explicitly that it is a documentation/summary tool rather than an action, but the title and text make that clear. Slight gap: it doesn't mention how the output is presented or whether it includes the exact submit_enquiry description.

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?

There are no parameters in the schemachers, so parameter semantics are trivial; with zero parameters, there is nothing to document. The description references the relevant context (what the enquiry does), which is enough. Even though the schema is empty ecc100%, the description adds value by explaining the nature of the tool itself.

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 a specific purpose: it is the read-first companion that explains what submit_enquiry does. It uses concrete language ('states what submit_enquiry does', 'nothing is paid', 'no quote is guaranteed') and differentiates itself from the actual submission sibling by being informational, not transactional.

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 opening imperative 'Read first' provides clear guidance to consult this tool before acting on submit_enquiry dropped. It doesn't explicitly list alternatives, but the subject matter is uniquely tied to submit_enquiry, and the title reinforces the distinction. However, there is no explicit 'when not to use' statement or comparison to other siblings like enquiry_fields.

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