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 value by disclosing that responses are sent to the provider for review, that it returns confirmation and updated order status, and that authentication is required. These go beyond the annotation hints and provide practical expectations for the agent.

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, front-loaded with the primary action, and includes essential outcomes in the second sentence. Every word contributes: no repetition of schema fields, no vague filler. It is concise and well-structured for quick agent comprehension.

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?

Given the tool's moderate complexity (nested answers object, 3 parameters, output schema exists), the description sufficiently covers purpose, outcome, and authentication. It does not explain prerequisites like needing to call provider_questions first, but the output schema and schema descriptions fill in many details. The description is complete enough for an agent to select and invoke correctly.

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 all parameters have descriptive text. The tool description does not add additional meaning beyond the schema: no formatting constraints, examples, or behavioral notes for parameters. It only mentions 'Requires authentication' which aligns with the bearer_token parameter, but does not enrich parameter understanding. Baseline 3 applies.

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 verb and resource: 'Submit answers to provider follow-up questions for a specific order.' It distinguishes from siblings like provider_questions (which likely requests questions) by specifying the submission action and intended recipient. The additional outcome 'sent to the provider for review' further clarifies the tool's unique role.

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 implies clear use context: use when you have answers to provider follow-up questions for an order. It does not explicitly exclude alternatives or provide when-not-to-use guidance, but the context is specific enough that an agent can infer when this tool is appropriate. No explicit alternative tools are named, but the sibling 'provider_questions' suggests the complementary flow.

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