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

The annotations establish that this is a non-read-only, non-destructive write operation, and the description usefully adds the economic consequence: 'Seller paid in full, stakes returned.' However, it does not clarify whether acknowledgement is irreversible, what permissions are required, or what preconditions must hold before calling it.

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 two tight sentences with no filler, and the core action is front-loaded before the outcome. The terseness is appropriate, though the domain term 'Class B' remains unexplained.

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?

This is a consequential state-changing acknowledgement in a multi-step marketplace flow, with no output schema and minimal annotations. The description states the settlement outcome but omits prerequisites, caller eligibility details beyond 'Class B buyer,' and any parameter guidance, leaving important gaps for safe invocation.

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?

Schema description coverage is 0% for the two required UUID parameters, and the description does not mention intentId or agentId at all. An agent gets no explanation of what identifier to supply beyond the bare parameter names.

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 names a specific verb and resource: a 'Class B buyer acknowledges the deliverable.' It also states the resulting settlement effect, so the core action is clear. However, it does not differentiate this tool from similar siblings such as confirm_delivery, verify_delivery, or release_payment.

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?

The only usage signal is that the caller is a 'Class B buyer' acknowledging a deliverable. There is no explicit when-to-use guidance, no prerequisites, no exclusions, and no comparison to related sibling tools that an agent could otherwise choose.

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