A4.1/5.0

Behavior3/5

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

Annotations already declare readOnlyHint, idempotentHint, and destructiveHint, so the safety profile is clear. The description adds the concrete clarification that no tax invoice is generated, which reinforces the read-only contract and prevents misuse, but it does not provide deeper behavioral context such as authentication needs or response characteristics. This adds modest value beyond 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.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is two short sentences with no filler. The main purpose is front-loaded in the first sentence, and the second sentence meaningfully disambiguates from invoice-generation tools. Every word earns its place.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness5/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For a zero-parameter, read-only tool with an output schema and rich annotations, the description is sufficient for safe and correct invocation. There are no prerequisites, parameters, or side-effect concerns that need additional explanation. The explicit negative statement also prevents a common misuse case.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters4/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

The input schema is empty with zero parameters, so there is nothing for the description to explain about parameters. Schema coverage is trivially complete, and the baseline for zero-parameter tools is 4. The description does not need to compensate for any parameter documentation gaps.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description states a specific verb ('Read') and resource ('platform invoice issuer settings'), making the action unambiguous. It also explicitly says 'Does not generate a tax invoice,' which distinguishes this tool from invoice-generation siblings such as auraspay_payment_invoice. This gives an agent a clear basis for selecting it.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines3/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description implies the tool should be used for reading invoice issuer settings rather than generating invoices, but it does not explicitly name a sibling alternative or state a condition for when to choose this tool over others. The exclusion of tax-invoice generation provides indirect guidance, but the agent must infer the intended selection context.

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