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

With no annotations, the description reveals the tool returns a deep-link URL and optionally captures a lead (a side effect). However, it does not disclose whether the quote is persisted, idempotency, rate limits, or auth requirements. The side effect is mentioned but understated.

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 sentences front-load the core purpose and return type. The second sentence adds optional contact handling. Could be slightly more structured by separating the components list from the lead capture, but still short and mostly efficient.

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?

Given 7 parameters including nested objects and no output schema, the description is too brief. It does not explain the purpose of each parameter (e.g., 'family', 'horsepower'), what the deep-link URL enables, or what happens on failure. The completeness is inadequate for an agent to reliably invoke the 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?

Schema description coverage is 0%, so the description must explain parameters. It lists components like 'propeller' and 'financing tier' that do not directly map to any schema properties (e.g., missing from schema parameters). Key parameters like 'family', 'boat_info', and 'horsepower' are not explained, leaving much ambiguity.

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 builds an itemized CAD quote listing explicit components (motor, installation, etc.) and returns a deep-link URL. This distinguishes it from siblings like estimate_trade_in or search_motors which focus on subtasks.

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 use for building a complete quote, but does not explicitly state when to use this vs. alternatives or provide conditions like prerequisites or when not to use. The mention of optional CRM lead capture hints at a specific use case but lacks clarity.

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