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

No annotations are provided, so the description must carry the full behavioral burden. It discloses the verification method (public node, not explorer), dual-node cross-check, and field-by-field HOLDS/FALLS return. However, it omits auth requirements, rate limits, latency, and failure/error behavior.

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?

Two sentences, front-loaded with purpose and method, then return format, then a direct usage recommendation. Every sentence earns its place with no wasted wording.

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 4-parameter verification tool with no output schema or annotations, the description explains the method, expected comparison, and return format well enough to invoke and interpret it. It leaves only edge-case/error behavior unspecified, which is a minor gap.

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 schema already defines tx, chain, token, and expect fields. The description adds that verification targets a token Transfer with expected amount and address, but does not add syntax or format details beyond the schema. Baseline 3 is appropriate when the schema does the heavy lifting.

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: independently re-derive and confirm an on-chain token Transfer against expected amount/address in a given tx. It explicitly distinguishes itself from an explorer and gives exact match criteria. No sibling tool competes for this purpose.

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?

Explicitly says when to use it: to check a payout receipt actually settled before trusting it. It also clarifies the method is a public node, not an explorer. It lacks when-not conditions or named alternatives, but the context is clear.

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