Messaging_createConfirmServiceDetails

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

With no annotations, the description must disclose behavior itself. It does disclose a message-sending side effect, but it does not mention required authorization/order context, whether the action is reversible, or what result the caller can expect. The 'Runs in your Kuudo deployment, not here.' line adds execution context but not behavioral transparency.

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 short and the second sentence conveys the actual action, but the opening 'Catalog entry.' is filler and the deployment note is placed before the purpose. While not bloated, the ordering weakens the definition's usefulness for quick scanning.

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?

The tool likely needs some context such as which customer/order and what service details to confirm, but neither the schema nor the description provides that; the schema is empty and the description only names the general scenario. With no annotations and no output schema, an agent lacks enough information to invoke the tool with correct inputs.

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?

The input schema declares zero properties, so there are no parameter semantics for the description to clarify; the 0-param baseline is 4. The description does not add parameter detail, but 'additionalProperties: true' might allow arbitrary inputs, and the description would be stronger if it warned about or named expected inputs. Still, no schema-described parameters exist.

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 identifies the core action ('Sends a message to contact a Home Service customer') and the resource/domain ('Home Service', 'service call'), which distinguishes it from sibling messaging tools like createConfirmOrderDetails or createConfirmDeliveryDetails. However, the first sentence 'Catalog entry. Runs in your Kuudo deployment, not here.' is a meta-comment rather than a functional statement, so it is not a fully crisp 5.

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 a clear use case: use this for arranging a service call or gathering pre-service information. It does not explicitly name alternatives, exclusions, or conditions such as 'use confirmCustomizationDetails instead when ...', so the guidance is present but not explicit about sibling differentiation.

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