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

Goes beyond the annotations by disclosing the concrete effect (funds released from escrow to the seller), the auth requirement (API key), and reinforcing irreversibility. The destructiveHint already flags the mutation, but the description adds meaningful financial and access context on top of 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?

Four short, front-loaded sentences: the action, the consequence, the irreversibility, and the prerequisite. Zero filler and the most decision-relevant facts come first.

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 destructive, irreversible payment-release tool with no output schema, the description covers the consequence, irreversibility, and auth need. It omits prerequisite state (e.g., order must be delivered) and error behavior, but an agent has enough to invoke it knowingly.

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% and the description never mentions order_id, its format, or where to obtain it. The single parameter is largely self-evident from its name and the UUID pattern in the schema, so the gap is not severe, but the description does nothing to compensate.

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 (accept delivered work) and the concrete effect: releasing escrowed USDC to the seller. It's clear what the tool does, but it never names the sibling alternatives (request_revision, open_dispute) that occupy the same decision point, so differentiation is left to inference.

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?

"Accept the delivered work" implies the triggering condition (work has been delivered), which is useful context. However, it offers no explicit guidance on when NOT to use it or how it compares to request_revision or open_dispute, which are the natural alternatives at this stage.

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