verify_vacation_rental_node

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

The description discloses the tool's read behavior ('Reads https://...') and confirms specific checks. Although no annotations are provided, the description implies non-destructive operation. It does not explicitly state there are no side effects, but the read-only nature is clear.

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 highly concise: two sentences that are front-loaded with purpose and followed by usage guidance. Every word adds value, with no redundancy or extraneous information.

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 lacks an output schema, and the description does not indicate what the tool returns (e.g., success/failure, verification result). While the purpose is clear, the agent misses critical information about the tool's output, making it incomplete for effective usage.

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 provides 100% coverage with a clear description of the 'domain' parameter. The tool description does not add additional parameter-level context beyond what is already in the schema, so 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 clearly states the tool's purpose: to verify a Vacation Rental Protocol host-domain node. It specifies the actions (reads well-known JSON, confirms VRP version, control, keys, endpoint) and distinguishes itself from sibling tools focused on booking operations.

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 gives explicit guidance on when to use the tool ('Use before trusting or quoting a host-domain offer'). While it does not exclude alternatives or mention when not to use, the context is clear and sufficient for an AI agent.

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