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

With no annotations, the description carries the full burden. It usefully discloses the required auth scope (verification.read) and tenant scoping, but says nothing about behavior for unknown IDs, IDs from other tenants, or that this is a non-mutating read. Some genuine value added, but a significant gap for a zero-annotation tool.

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 short sentences with the core action front-loaded; the template indentation is cosmetically noisy but adds no wasted content. Efficient, though it could have used the second sentence for more than just the scope requirement.

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 single-param read tool with no output schema, the description should indicate what a 'verification result' contains (status, timestamps) and state that it is a non-mutating read. It conveys the tenant boundary and scope but leaves the return shape and read-only nature implicit.

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 there is one parameter, verification_id. The description never explains where the ID comes from, its format, or whether it must be one this tenant owns; 'belonging to the authenticated tenant' only faintly implies scoping. It fails to compensate for the schema gap.

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 ('Retrieve') and resource ('a verification result'), scoped to the authenticated tenant, so an agent can distinguish this read from the write-oriented sibling verify_supplier_payment. It stops short of naming that sibling or explicitly contrasting the two, which keeps it at 4 rather than 5.

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 implied by the resource ('verification result') and the tenant scoping, but there is no statement of when to call this versus verify_supplier_payment, nor any prerequisite such as needing a verification to exist first. Adequate context, no explicit alternatives or exclusions.

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