Messaging_confirmCustomizationDetails

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

With no annotations, the description carries the burden. It discloses a buyer-facing side effect (sends a message) and the unusual routing context ('Runs in your Kuudo deployment, not here'). It does not mention permissions, response behavior, or idempotency, but the core side effect is clearly stated.

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 contains no filler. The functional sentence is clear, though leading with 'Catalog entry' and 'Runs in your Kuudo deployment, not here' puts routing metadata before the core behavior.

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 simple, zero-parameter catalog entry the description conveys the operation and runtime location. It still lacks any indication of the response/return value, and the 'not here' deployment note is ambiguous about whether this tool can actually be invoked from the current environment.

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 parameters and has 100% coverage, so the description does not need to add parameter-level detail. The additionalProperties:true caveat is not explained, but with no declared inputs this is a minor gap.

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 action: sends a message asking a buyer to provide or verify customization details, with concrete examples (name spelling, images, initials). This clearly differentiates it from sibling messaging tools like confirm delivery, order, or service details, although it does not name them explicitly.

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?

Use is implied from the action: an agent should select this tool when a buyer needs to provide or verify customization details. However, it gives no explicit when-to-use guidance, prerequisites, or comparison to alternatives such as the createConfirm* messaging tools.

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