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

Annotations already declare readOnlyHint=true and destructiveHint=false, so 'Changes nothing' is largely redundant with structured data. However, the description adds real behavioral value by spelling out the return payload — the set of possible verification states plus 'changes requested' and hold/rejection reasons — which matters because no output schema exists.

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?

Three short sentences, no filler, with the core outcome and the state enumeration front-loaded. The opening 'Where the verification has got to' is colloquial but brief and unambiguous in context.

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 return-value burden and does so well by listing states and the accompanying reasons. It covers scope (business verification) and the optional-act-as-yourself behavior is handled by the schema. Minor gap: no explicit mention of redirecting to submit/resubmit on a rejected state.

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 coverage is 100% and the single 'business' parameter is fully documented in the schema (including the omit-to-act-as-yourself semantics). The description adds nothing about the parameter, so the 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?

States a specific verb and resource — returns the business verification state — and enumerates the exact state values (not started, in review, changes requested, on hold, rejected, verified). This clearly separates it from the mutation siblings agenta_verify_submit, agenta_verify_resubmit, and agenta_verify_declaration, and from the generic agenta_status_get.

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?

Usage is only implied: 'Changes nothing' signals a read-only lookup and the enumeration of states hints at when the agent would call it, but there is no explicit when-to-use or when-not guidance relative to verify_submit or status_get. Minimum viable routing guidance.

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