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

Annotations already declare readOnlyHint=true and destructiveHint=false, and the description adds no behavioral context beyond that—it does not mention evidence submission, oracle attestation, paymentProof-triggered price quotes, or any side effects. It neither contradicts nor enriches the annotations.

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, but it is under-specified rather than efficiently structured. Three words provide no usable context for a tool with four parameters and an output schema, so the brevity does not earn 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?

While the input schema and output schema cover parameter mechanics and return shape, the description fails to explain the verification process, the role of criteria/evidence, or when this tool should be selected. An agent cannot determine whether this is a read-only attestation, a payment-gated verification, or part of a dispute workflow.

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 100%, so the input schema already documents all parameters, their types, constraints, and optionality. The description contributes no parameter-level detail, but with complete schema coverage the baseline score of 3 is appropriate.

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 'Escrow oracle verification' essentially restates the title 'Verify Escrow Work' and tool name without specifying what the tool actually does, what it returns, or how verification is performed. It names a vague concept ('oracle verification') but does not distinguish this tool from sibling tools like escrow.agent_to_agent.

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 guidance on when to use verify_work instead of related escrow, security, or certification tools. The name hints at a verification context, but no conditions, prerequisites, exclusions, or alternative tools are mentioned.

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