Behavior2/5

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

With no annotations, the description bears full responsibility for behavioral disclosure. It only states the action ('Generate') without explaining whether the report is generated synchronously or asynchronously, any side effects, required user consent, or processing time. This is insufficient for a report-generation tool.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness2/5

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

The description is a single sentence and technically concise, but it is under-specified and omits critical details. True conciseness requires conveying essential information efficiently, which is not achieved here.

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

Completeness2/5

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

Despite having an output schema and moderate complexity (3 parameters, many sibling tools), the description fails to explain the report output, scope, or how parameters influence results. It is incomplete for an agent to use correctly without guessing.

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

Parameters2/5

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

Schema description coverage is 0%, and the description adds no meaning beyond parameter names. It does not explain the purpose of 'from_date', 'account_ids', or how they affect the report. The agent would have to infer functionality solely from parameter names, which is poor.

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

Purpose4/5

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

The description clearly states the tool generates a 'Verification of Assets (VOA) report', specifying the action and resource. However, among many sibling report tools (e.g., generate_voi_report, generate_voai_report), it does not distinguish itself, resulting in a slight deduction for lack of differentiation.

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

Usage Guidelines2/5

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

No guidance is provided on when to use this tool versus alternatives like generate_voi_report or generate_voai_report. There is no mention of prerequisites, dependencies, or context, leaving the agent without decision-making support.

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