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

No annotations are supplied, so the description carries the full behavioral burden, and it discloses nothing: no mention of the computation performed, expected input format, units, or return value. For a financial calculation tool with zero annotation coverage this is a complete gap.

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 text is short, but this is under-specification rather than conciseness — a single repeated phrase that conveys no actionable information. Brevity here is not a virtue because nothing useful is communicated.

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?

With no output schema, no annotations, and a domain-specific calculation, the description should at minimum state the formula or the meaning of the result. It supplies none of that, leaving the agent unable to call the tool correctly or interpret its output.

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%, so the baseline of 3 applies per the rubric. However, the schema descriptions are placeholder text ('CurrentAssets to process'), and the description adds no clarification of what these values represent or in what format they should be supplied.

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 'Working Capital: Working Capital' merely restates the tool name and title with no verb or operation named. It is a tautology: an agent learns nothing about whether it computes, stores, or validates working capital, nor how it differs from the many finance siblings such as x402-current-ratio or x402-quick-ratio.

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 when-to-use guidance, no prerequisite (e.g., that currentAssets and currentLiabilities are needed), and no routing to or away from any alternative. Nothing in the text helps an agent decide whether this tool applies to its task.

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