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

Beyond the annotations, the description reveals important side effects: up to four licensed agents receive the request and contact details under contact_consumer, sell_identity permits sharing with marketing partners, nothing leaves without consent, every delivery and refusal is receipted, and POST /forget revokes. This gives an agent a strong model of the real-world impact of calling the tool.

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 definition is dense but efficient: it front-loads the core purpose, then layers prerequisites, consent mechanics, scope behavior, and side effects without repetition or filler. Every clause adds information an agent needs to invoke the tool correctly.

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?

For a tool with 9 parameters, nested objects, and no output schema, the description supplies the most critical context: prerequisites, consent handling, scope semantics, side effects, and revocation. It falls short only by not describing the exact response shape and by leaving several optional parameters unexplained.

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 description adds meaning by sourcing quote_id from get_quotes and by explaining the consent and scope semantics. However, with schema coverage at 44%, it does not compensate for the undocumented optional parameters like best_time, email_address, preferred_channel, or the full_name context, and it does not explain verify_token's role beyond what the schema already says.

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 opens with an explicit action and outcome: 'Connect the consumer with licensed insurance agents who can quote firm and bind,' which clearly states the resource and purpose. It is unambiguous and unlikely to be confused with sibling lookup/registration tools, though it does not explicitly compare itself to them.

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 gives concrete prerequisites: the quote_id must come from get_quotes, and the consumer's name, phone, and explicit consent are required. It also explains scope-dependent behavior and consent modalities. It lacks explicit when-not-to-use guidance or named alternatives, but the context and sequencing are clear.

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