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

Annotations already declare readOnlyHint, idempotentHint, and destructiveHint, so the safety profile is covered. The description adds useful behavioral context by stating the envelope is non-binding and untransmitted, clarifying that 'create' does not mean persistence or transmission. It does not discuss auth or return behavior, but annotations carry much of the burden.

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 a single sentence with the key qualifiers front-loaded. The nine-item coverage list is compact but somewhat vague; it earns its place by conveying scope, though it could be more 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?

With no output schema and a sparse description, an agent lacks guidance on how to construct the query, what terms and constraints should contain, why capability_id is required, or what the tool returns. For a tool with nested objects and four parameters, this is incomplete.

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%, and the description does not name or explain any of the four parameters (query, terms, constraints, capability_id). The list of coverage areas (price, volume, limits, etc.) hints at what the envelope contains but does not map to specific parameters or clarify required inputs.

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 states a specific verb ('Create') and resource ('quote-request envelope'), and clarifies scope with 'non-binding, untransmitted'. This distinguishes it from submission and validation siblings and gives a clear sense of what the tool produces.

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 qualifiers 'non-binding, untransmitted' imply this is for preparing a request rather than sending it, but there is no explicit when-to-use guidance, no exclusions, and no mention of alternative tools. Usage context is implied rather than stated.

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