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

Annotations already declare readOnlyHint false, idempotentHint true, and destructiveHint true. The description adds that responses are sent to the provider and that it returns confirmation and updated order status, plus requires authentication. However, it does not explain the destructive hint (e.g., overwriting previous responses), leaving some behavioral ambiguity.

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 two sentences, immediately stating the action and outcome. It is concise, front-loaded, and contains no wasted words.

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 an output schema present, return values are already documented. The description covers the main action, the need for authentication, and the effect (responses sent to provider, order status updated). It omits the prerequisite relationship with provider_questions and the destructive overwrite behavior, but given the tool's simplicity and existing structured hints, it is sufficiently complete.

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%, with each parameter having a description. The tool description adds no additional parameter-level meaning; for instance, the 'answers' object's keyed-by-question-ID structure is already in the schema. Thus the description does not enhance the schema's parameter semantics.

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 uses a specific verb 'Submit answers' and identifies the resource as 'provider follow-up questions for a specific order.' This clearly distinguishes it from the sibling tool 'provider_questions' (which retrieves questions) and other submission tools like intake_submit.

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 clear context: it is for submitting answers to a specific order's provider follow-up questions and requires authentication. It does not explicitly name alternatives or state when not to use it, but the context is unambiguous enough for an agent to infer the appropriate use case.

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