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

The description adds a couple of behavioral details such as server-side validation and the production of a structured deliverable, which goes slightly beyond the readOnlyHint annotation. It does not contradict annotations, but it does not disclose any additional side effects, rate limits, or authorization requirements.

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 description is relatively short but contains promotional language ('Gapup agent-payable C-suite expertise (RISK)') and a reference case that is illustrative but not essential. The core functional content is compact, but the marketing fluff reduces efficiency.

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?

This is a complex tool with nested objects, multiple enums, and no output schema, yet the description does not explain required vendor fields, risk frameworks, assessment purpose, or the deliverable's structure. The instruction to 'send the documented case fields' is too vague for an agent to know what to provide, making the description incomplete for effective use.

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?

The description does not explain any of the parameters at all, only referring vaguely to 'documented case fields.' With schema description coverage at only 20%, the description fails to clarify the meaning of company, vendors, riskFramework, assessmentPurpose, or the nested fields, leaving an agent without adequate information to construct a valid request.

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 clearly identifies the tool as a vendor risk assessor that returns a structured, audited deliverable, and provides a concrete reference case. However, it does not explicitly differentiate this tool from sibling risk-related tools such as cyber_risk_auditor or supplier_esg_audit.

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?

There is no guidance on when to use this tool versus alternatives, nor any reference to exclusions or specific use cases. The reference case implies a typical scenario but does not state the appropriate context or distinguish it from other risk assessment tools.

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