ExternalFulfillmentShipments_updatePackageStatus

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

With no annotations, the description must disclose behavioral traits itself. It notes that the tool runs in a Kuudo deployment rather than here, which is useful, but it does not explain status values, required identifiers, side effects, permissions, or response behavior. This is thin for a mutation-like operation.

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 mostly to the point, but 'Catalog entry' is a weak opener and the actual purpose appears last. It is concise, yet the ordering does not front-load the action an agent needs most.

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?

Despite having no declared parameters, the tool still needs context about which packages are affected, what status values are valid, and how the 'not here' execution model affects invocation. Sibling tools overlap enough that the lack of disambiguation makes this definition incomplete for reliable use.

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 schema declares zero properties, so there are no parameter names or descriptions for the schema to capture. The description adds no parameter detail, but with 0 params the baseline is already 4; however, additionalProperties: true leaves input semantics vague.

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 clear action verb and resource: 'Updates the status of the packages.' However, it does not distinguish this from the closely named sibling updatePackage, and 'the packages' is underspecified.

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 phrase 'Runs in your Kuudo deployment, not here' gives operational context but no guidance on when to choose this tool over alternatives like updatePackage or processShipment. No exclusions or conditions of use are provided.

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