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

Annotations already declare readOnlyHint=false, destructiveHint=true, openWorldHint=true and idempotentHint=false, so the safety profile is covered. The description adds that the payload is forwarded to a third-party business and is form-scoped, but it does not explain the destructive/non-idempotent consequences (e.g., duplicate submissions, whether a request can be withdrawn).

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 short sentences with the action and target front-loaded; the scoping sentence carries real information. No filler or restated boilerplate, though it stops just short of maximal density.

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?

An output schema exists, so return values need no explanation, and the schema fully documents the 8 parameters. What remains missing is the consequence of a destructive, non-idempotent write to an external business and the relationship to the request_* siblings, which is thin for an 8-parameter mutation 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 100%, so every parameter including the consent gate, ISO-8601 start format and optional phone/service_address rules is already documented in the schema. The description merely restates a subset of those fields, adding no format or constraint detail beyond the structured data.

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 and resource: it 'sends the user's quote request ... to the chosen business', and it enumerates the payload fields. It is clear on its own, but it never distinguishes itself from closely named siblings like request_service or request_booking, leaving overlap unresolved.

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?

'Called by the quote form only' is a real usage constraint that tells the agent this is not a general-purpose submission tool, which is more than nothing. However, it names no alternatives and gives no condition for choosing request_service or request_booking instead, so the routing guidance is only implied.

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