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

The annotations already declare readOnlyHint=true and openWorldHint=false, and the description repeats 'Read-only' without adding much beyond that. It adds context about what the content covers (checklist, pricing policy, human advisor follow-up), but it does not describe return format, caching, rate limits, or any other behavioral traits.

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 compact two-sentence definition with no filler. The main content is front-loaded, though the phrase 'The checklist a traveller or agent should send' is slightly awkward and could be reworded for clarity.

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 that the tool has no parameters, no output schema, and a read-only annotation, the description sufficiently explains what the tool offers and for whom. It does not specify the exact format or structure of the checklist, but that is not necessary for an agent to invoke a zero-parameter informational tool correctly.

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, so there is nothing a description must compensate for. The absence of parameter discussion is appropriate, and the description focuses on what the tool provides rather than input semantics.

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 identifies the tool as a reference checklist for travellers or agents requesting a bespoke proposal, covering pricing policy and human-advisor follow-up. It is not a tautology and the 'Read-only' tag helps distinguish it from the sibling tool request_a_proposal, though it does not name that alternative explicitly.

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 the tool is a how-to guide by saying 'The checklist... should send...', so an agent can infer it is meant to be read before or while requesting a proposal. However, it does not explicitly state when to use this tool versus request_a_proposal or mention any prerequisites or exclusions.

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