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

There are no annotations, so the description carries the full burden of behavioral disclosure. It clearly explains side effects: the enquiry is not submitted until step 2, an email is sent, and providers see nothing until the person clicks a link. This is unusually transparent.

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 long, but nearly every sentence carries necessary process information. It is front-loaded with the core purpose and caveat, then walks through the two steps. It could be tightened with bullet formatting, and the 'not a purchase' point repeats the title, but it remains efficient enough for the complexity involved.

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 description fully covers the two-step flow, consent requirement, confirmation token behavior, email activation step, and the exact consent text. For a tool with no output schema, it still names what step 1 returns and what step 2 accomplishes, leaving no critical gap for an agent to call it 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 input schema already documents all three parameters, so the baseline is 3. The description adds valuable semantics by explaining that confirmation is the token returned in step 1, that the same answers and consent must be reused in step 2, and that answers come from enquiry_fields. This goes beyond the schema without being redundant.

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?

States a clear verb and resource: 'Submits an enquiry to Golden Visa Calculator.' It also distinguishes itself from a purchase or guaranteed quote, which separates it from sibling tools like calculate and leaves no ambiguity about what the tool does.

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?

Provides explicit when-to-use guidance: call first with answers and consent, show the summary, then call again with the confirmation token only if the person agrees. It also points to enquiry_fields for answer keys, making the correct invocation sequence fully specified.

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