EasyShip_updateScheduledPackages

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

With no annotations, the description carries the full burden. It usefully discloses that this is a catalog entry that runs in the caller's Kuudo deployment, not in the tool environment, and that it mutates the slot. However, it does not mention required permissions, side effects, or failure behavior.

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 every clause adds information, including the unusual deployment caveat. 'Catalog entry' is slightly cryptic and the purpose appears after the caveat, which is why it is not a 5.

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?

For a mutating operation with no annotations and no output schema, the description is thin: it identifies the package but not the payload shape, accepted time-slot values, response, or prerequisites. An agent could select it but would have to guess at invocation details.

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 no properties and allows additional properties, so the description's mention of 'specified scheduledPackageId' is the only documentation of the parameter. It adds semantic meaning but omits type, format, requiredness, and any time-slot arguments needed to perform the update.

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 ('Updates') and resource ('time slot for handing over the package indicated by scheduledPackageId'), making the operation clear and distinct from EasyShip_getScheduledPackage and EasyShip_createScheduledPackage. It does not explicitly contrast with siblings, so it stops short of a 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?

No guidance is given on when to choose this over alternatives, prerequisites, or when not to use it. The only operational note is that it runs in the Kuudo deployment rather than here, which is a deployment caveat, not a usage-versus-alternative guideline.

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