Messaging_CreateAmazonMotors

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 states the side effect—sending a message to a buyer—but omits prerequisites, eligibility rules, consent requirements, whether sending is immediate or queued, and failure behavior. 'Runs in your Kuudo deployment' adds some execution context but is vague and unexplained.

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 front-loaded, with the core action in the final sentence. However, 'Catalog entry' is cryptic and contributes little, while 'Runs in your Kuudo deployment, not here' is unexplained. It is compact but sacrifices clarity.

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 tool with no annotations and no output schema, this description is incomplete. It provides only the basic action and an unclear execution-location note, leaving an agent without enough information about required inputs, permissions, side effects, or expected results.

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 has zero parameters and schema description coverage is effectively complete, so there is little for the description to add; the zero-parameter baseline is 4. The description could have noted expected implicit inputs such as order identifier and message details, especially since additionalProperties is allowed, but no schema parameters exist to document.

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 clearly states the core action: 'Sends a message to a buyer to provide details about an Amazon Motors order.' This identifies a specific verb, resource, and context that distinguishes it from generic Messaging siblings. However, the opening 'Catalog entry. Runs in your Kuudo deployment, not here' muddies whether this is actually an invokable tool, preventing 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?

There is no explicit guidance on when to use this tool versus alternatives like Messaging_createUnexpectedProblem or Messaging_CreateWarranty. The phrase 'Runs in your Kuudo deployment, not here' is a location/context cue, not a when-to-use or when-not-to-use guide. No alternative tools are named.

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