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

Annotations already declare readOnlyHint=true and destructiveHint=false, so the 'Read-only' statement is largely redundant. However, the description adds real value by enumerating the return payload (the five statements, unsupported categories, false-statement consequences), which the absent output schema otherwise leaves undisclosed. The openWorldHint=true is not addressed.

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 content is front-loaded and there is little filler, but the opening fragment 'The five statements --accept-declaration attests to.' is awkward and would confuse a reader skimming the first clause. A small edit would make the whole entry tighter.

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?

With no output schema, the description carries the burden of describing the return value and does so reasonably well (three categories of returned content). For a simple read-only, zero-required-param tool, this is close to sufficient; a note on formatting or pagination would complete it.

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% and the single 'business' parameter (optional, omit to act as yourself) is fully documented in the schema. The description adds nothing about it, so baseline 3 applies.

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?

Specific verb-resource pair: it returns 'the five statements a merchant attests to when submitting business verification,' plus the unsupported product categories and the false-statement consequences. An agent can distinguish this read-only declaration viewer from sibling write tools like agenta_verify_submit without opening the schema.

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?

Explicit sequencing guidance: 'Show these to the merchant before calling agenta_verify_submit with acceptDeclaration true.' This names the alternative tool and the condition that triggers it, leaving nothing to inference.

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