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

No annotations are provided, so the description carries the full burden of behavioral disclosure. It prominently states the cost ('Costs 1 API credit') and lists numerous return categories, giving agents a realistic picture of the tool's scope. It does not discuss error handling, rate limits, or read-only status, but the '$get$' action implies a safe read.

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 single, front-loaded sentence that starts with the primary purpose and then systematically lists data categories. It is somewhat lengthy, but every listed item provides meaningful scope information and serves a purpose.

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?

Without an output schema, the description must explain return values, and it does list many data categories. However, it lacks detail on the response structure, units, or failure behavior, which is a notable gap for a comprehensive data tool.

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 fully describes the address parameter with an example, achieving 100% schema coverage. The description adds only a broad 'any US address' scope and does not provide additional formatting or syntax details beyond what the schema already provides.

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 specifies the action ('Get') and the resource ('comprehensive property risk data for any US address') and even enumerates many data sources. However, it does not explicitly differentiate from the sibling tool get_property_report, so it is clear but lacks explicit sibling differentiation.

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 usage when property risk data for a US address is needed, but it provides no explicit guidance on when not to use this tool or when to prefer the sibling tool get_property_report. No alternatives or exclusions are mentioned.

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