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

Annotations already declare readOnlyHint=true, openWorldHint=false and destructiveHint=false, so safety and locality are covered by structured data. The description adds that this is a starting/orientation call and that content is static reference material, but no rate limits, auth requirements or return format are described, so the added behavioral value is modest.

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?

Two short sentences, front-loaded with the resource identity and followed by the actionable directive. Every clause earns its place by listing concrete returned content.

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?

There is no output schema, but the description compensates by enumerating the categories of information returned (licence, lines, states, contact, hours), which is exactly what an agent needs to decide to call it. With zero parameters and full annotation coverage, nothing material is missing.

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 takes zero parameters, so there is no parameter semantics for the description to clarify; the baseline for a zero-parameter tool applies. The description correctly signals that no inputs are needed by framing this as a plain informational lookup.

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 names a concrete resource (the agency itself) and enumerates exactly what it returns: licence, lines and states written, contact details and hours. This is immediately distinguishable from the siblings check_appetite, request_quote and start_online_quote, which are all transactional actions rather than static reference data.

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?

"Call this first" gives explicit ordering guidance that tells the agent when to reach for this tool ahead of the others. It stops short of naming alternatives or stating when not to use it, so it falls one step below fully explicit routing guidance.

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