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

No annotations are provided, so the description carries the full behavioral burden, and it discloses nothing: not whether it is a pure computation or a mutation, not required inputs (required parameters = 0, so the agent does not know which of beta/debt/equity/taxRate are actually needed), and not what is returned. This is a total disclosure 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?

It is short, but shortness here is under-specification rather than conciseness: the single clause is pure redundancy of the title with zero informational content. Nothing meaningful is front-loaded because nothing is said.

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 four-parameter financial calculation tool with no annotations and no output schema, the definition supplies essentially none of the context an agent needs — no formula, no input requirements, no return shape. It is inadequate in every dimension.

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%, which sets the baseline at 3 even though the description adds no parameter meaning. The schema descriptions themselves are placeholder-level ('Beta to process', 'Debt to process'), so neither the schema nor the description explains units, formats, or which combination drives the result.

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 'Beta Levered: Beta Levered' merely restates the tool name with no verb, no resource, and no indication of what computation is performed. An agent cannot tell from this text whether the tool returns a levered beta value, transforms a beta, or does something else — and it does not distinguish it from the sibling x402-beta-unlevered.

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 prerequisites, and no mention of alternatives such as x402-beta-unlevered. The description gives the agent nothing to route on.

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