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

Annotations already declare readOnlyHint=true, destructiveHint=false and openWorldHint=true, so the safety profile is covered. 'Changes nothing' largely restates readOnly, and the useful addition is the timing note that the PDF link appears only once the report is written. No pagination, auth or failure behavior is discussed.

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 prose is brief, but the first fragment is malformed and the second sentence repeats the PDF-availability point already made in the first ('download the report PDF once it exists' / 'the report PDF link once it is written'). Minor redundancy and a weak lead-in keep it from being clean.

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 zero-required-parameter read tool with rich annotations and no output schema, the description does the important work of enumerating the returned fields (requested flag, state, grade, PDF link). Only the implicit prerequisite that an audit must first be requested is left for the agent to infer.

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%, with each of the three parameters (output, business, download) fully documented in the schema itself. The description adds no syntax, default or scoping detail beyond the schema, 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?

The description names the resource (audit state / report PDF) and enumerates exactly what is returned: whether an audit was requested, its state, grade and PDF link. The opening clause ('The audit state, and download the report PDF...') is grammatically broken, but the second sentence rescues the intent and separates this read tool from the sibling agenta_audit_request.

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: you call it to inspect the state of an audit you (or the request tool) started. The phrase 'once it exists' hints at the prerequisite that an audit must first be requested, but no alternative is named and no when-not guidance is given.

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