Shipping_linkCarrierAccount

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

With no annotations, the description carries the full burden of behavioral disclosure. It does reveal that it runs in a separate deployment and that two operations share the name, but it omits side effects, auth requirements, idempotency, or output behavior for a mutating link 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, but the actual purpose is buried after 'Catalog entry' and the environment note. The meta-statements are somewhat useful but the structure could front-load the operation more effectively.

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?

It includes important context about the deployment location and the name collision between two API operations, which helps an agent avoid mis-invocation. However, it never explains how the carrier account is specified, what the response looks like, or whether direct invocation is intended at all.

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 has zero declared parameters, so the baseline is 4 and there is little to document. The description only mentions a 'specified carrier account' without indicating what parameter carries that identifier, which is a minor gap given additionalProperties is allowed.

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?

States a specific verb and resource: associates/links the specified carrier account with the merchant. It is clear enough to identify the intended operation, though the 'Catalog entry' preface and lack of explicit sibling differentiation keep it from 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?

Provides no when-to-use vs. when-not-to-use guidance, no named alternatives, and no prerequisites. The action itself weakly implies a use case, but the 'Runs in your Kuudo deployment, not here' note is confusing about whether this tool should even be invoked from the current environment.

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