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

With no annotations, the description must carry the full burden of behavioral disclosure. It discloses that the operation runs elsewhere and is restricted to VOC vendors, but it gives no indication of what happens when called, such as side effects, return values, or errors. The behavior itself remains opaque.

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 front-loaded with the most critical context: 'Catalog entry. Runs in your Kuudo deployment, not here.' The VOC vendor restriction is also valuable. However, the phrase 'Catalog entry' is somewhat redundant with the deployment statement and does not add substantive meaning, so not every sentence earns its place.

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 description is incomplete for an operation with a descriptive but ambiguous name. It fails to explain what 'submitShipmentStatusUpdates' entails, how it relates to the many sibling shipping operations, or what the caller should expect. Given no annotations and no output schema, the description should provide much more functional context.

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?

There are no parameters, so schema coverage is vacuously 100%. The baseline for zero-parameter tools is 4, and the description does not need to explain parameter details. No credit is lost for missing parameter information that simply does not 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 says 'Catalog entry' but never states what the operation actually does. It provides execution context (runs in Kuudo deployment) and eligibility (VOC vendors), but the reader must infer the action from the tool name 'submitShipmentStatusUpdates'. The purpose is vague and does not define a verb+resource relationship.

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?

Gives clear context on when this tool applies: only for Vendor-Own-Carrier (VOC) vendors and only in the customer's Kuudo deployment, not here. It does not mention alternatives or exclusions relative to sibling tools, but the deployment and audience constraints are explicit and useful.

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