Messaging_createUnexpectedProblem

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

With zero annotations, the description carries the full disclosure burden. It does disclose the key side effect (sends a critical, customer-facing message) and adds the deployment context that the operation runs in the Kuudo deployment, not here. However, it does not address reversibility, prerequisites, failure behavior, or permission requirements, and the ambiguous 'Catalog entry' phrasing clouds whether the tool is actually executable.

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?

Three short sentences totaling roughly 30 words with no filler. The deployment caveat and catalog-entry status are front-loaded before the purpose statement. The two cryptic fragments ('Catalog entry.' and 'Runs in your Kuudo deployment, not here.') could be merged or expanded, but 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?

Adequate for a zero-parameter, no-output-schema tool: the description covers what the tool does and where it executes. But the 'Catalog entry' phrasing is ambiguous, there is no guidance on what context is needed to invoke it (which buyer/order), and no mention of what happens on success or failure. It is minimally viable with clear gaps.

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 tool has zero defined parameters, so per baseline the description need not explain parameter semantics. Schema coverage is trivially 100%. The one gap is that additionalProperties is true with no guidance about what unstructured inputs (e.g., order identifier, message content) the operation may expect, but this does not lower the score below baseline.

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 states a specific verb and resource: 'Sends a critical message to a buyer that an unexpected problem was encountered affecting the completion of the order.' The trigger scenario ('unexpected problem...affecting completion') distinguishes it from sibling messaging tools like Messaging_createConfirmOrderDetails or Messaging_CreateAmazonMotors. It does not name a sibling it is not, which keeps 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?

Usage context is only implied through the scenario ('unexpected problem was encountered affecting the completion of the order'); there is no explicit when-to-use guidance, no when-not-to-use conditions, and no alternative tools named. The 'Runs in your Kuudo deployment, not here' caveat addresses environment rather than tool selection.

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