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

Annotations already declare readOnlyHint=false, idempotentHint=false, openWorldHint=true, and destructiveHint=false. The description adds context beyond that: the pricing call is cached, repeat calls return the stored estimate, a mandatory disclosure notice must accompany the prices, and carrier names come from the agent rather than the response. The phrase "Carrier names are shared by the agent" is ambiguous (does the tool omit them or does the agent supply them?), which is the main gap.

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?

Three short front-loaded paragraphs: capability, return payload, then compliance and next step. Almost every sentence earns its place. The one low-value/ambiguous sentence is the carrier-name note, which adds confusion rather than clarity.

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?

With no output schema, the description does the work of describing the response shape in detail, and it flags the legal notice requirement for a pricing tool. Given non-readonly, non-idempotent annotations, it would be stronger if it named the upstream tool that yields a valid quote_id and said what happens when the quote is not yet verified.

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?

There is one parameter at 0% schema description coverage, so the description must carry the meaning. It tells the agent the quote_id refers to a verified estimate and that the same id is passed to request_agent to apply, which is genuinely useful. It never says where the quote_id originates (start_life_quote or verify_contact), leaving the parameter's provenance unexplained.

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?

States a specific verb and resource: "Prices a verified term life estimate" and enumerates exactly what comes back (best monthly premium, carrier count, up to 5 options with premium, AM Best rating, exam flag). The first-call/later-call distinction is a useful behavioral nuance. It stops short of naming the sibling that produces the verified quote (start_life_quote/verify_contact), so differentiation from get_quote_status and start_life_quote is inferred rather than stated.

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?

Gives an explicit next step and the sibling to use for it: "To apply, call request_agent with the quote_id." The prerequisite is implied by "verified" but not spelled out, and there is no guidance on when to use this versus get_quote_status or start_life_quote, so the agent must infer the entry point.

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