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

The description goes far beyond the readOnlyHint annotation (false), providing extensive behavioral disclosure: it's a simulation, no real carrier bound, no premium charged, no coverage issued, and no payment accepted. It also specifies the return payload categories, giving the agent a clear picture of what to expect. This is exemplary transparency for a demo 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 description is three brief sentences that efficiently convey purpose, returns, and demo constraints. It front-loads the core function and adds essential caveats without redundancy. Every sentence earns its place, and it avoids unnecessary detail.

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 demo tool with 5 required parameters and no output schema, the description fully covers what it does, what it returns, and the demo limitations. The precondition (quote_id from get_parametric_quote) is stated. There are no nested objects or complex outputs requiring elaboration, so nothing essential 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?

Schema description coverage is 100%, so the baseline is 3. The description adds minimal parameter-specific value beyond the schema: it repeats the quote_id source (already in the schema) and mentions payment_method only implicitly via 'No payment is accepted'. It does not explain broker_email, client_business_name, or client_contact_email beyond their schema descriptions, so no significant added meaning.

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 simulates accepting a demo quote and binding a policy, and lists the specific returns (demo policy_id, dates, trigger details, confirmation). It distinguishes itself from siblings by emphasizing the demo nature and referencing the get_parametric_quote tool as the source of quote_id, making its purpose unambiguous.

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?

It explicitly instructs to pass quote_id from the demo get_parametric_quote tool, establishing a clear precondition and sequence. It also clarifies this is a demo with no real carrier, premium, or coverage, which guides appropriate use. However, it does not mention alternative tools for different actions (e.g., get_policy_status for checking policy) or explicitly state when not to use it, leaving some room for interpretation.

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