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

With no annotations provided, the description carries full burden. It discloses the cost ($0.10/call) and support for existing assessmentId projects, but it does not clarify whether the tool persists data, mutates existing assessments, or is read-only. The phrase 'create the property benchmark' suggests a write operation, yet side effects and reversibility are undisclosed.

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 relatively concise and front-loaded with the main action and outcome in the first sentence. The 'Quote Guardian' label adds minor redundancy but is not harmful, and the cost note is a useful addition. Overall, it is efficient and structured.

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 has 10 parameters, no output schema, and no annotations, so the description must provide substantial context. It covers the high-level purpose but omits critical details such as required input relationships, behavior for different service types, output format, error handling, and side effects, making it incomplete for a tool of this complexity.

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?

Schema description coverage is only 40%, and the description highlights postalCode and quoteText without explaining the other parameters (city, state, serviceType, propertyType, monthlyBillRange, apiKey, country). It does clarify the mutual exclusivity of postalCode and assessmentId, but it fails to compensate for the majority of undocumented parameters.

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 defines the tool's purpose: submit postalCode and quoteText to create a property benchmark, review risks across price, sizing, equipment, financing, and warranty, and receive a secure Builder checkout handoff. This specific verb+resource structure distinguishes it from sibling tools like get_quote_link or create_energy_assessment.

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 used when you have an installer quote and need a comprehensive review plus checkout handoff, and notes that existing assessmentId projects remain supported. However, it does not explicitly compare against alternatives or state when not to use it, leaving the guidance at an implied level.

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