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

With no annotations, the description carries the full burden but only reveals the cost ($0.001 USDC via x402) and the broad category. It does not disclose required inputs, output format, potential side effects, or any operational behavior beyond the payment requirement.

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 very short and under-specified. While it is not verbose, it lacks the necessary information to be considered well-structured; the one-liner is more of a placeholder than a functional description.

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?

Given the absence of annotations, no output schema, and a generic parameters object, the description is grossly incomplete. It provides no information about expected inputs, return values, or behavior, leaving the agent completely in the dark.

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 schema's only parameter is a generic 'params' object with the description 'Tool parameters as JSON object', which provides no actual parameter semantics. The description adds no additional meaning about what parameters the tool accepts, making it impossible to know what to pass.

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 merely restates the tool name ('tax bracket') and labels it as a 'Finance & Math tool' without a specific verb or resource, so it does not clearly state what action the tool performs. It fails to differentiate from the many other finance/math tools in the sibling list.

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, what scenarios it fits, or how it compares to alternatives. The mention of cost is a payment note, not a usage context or exclusion.

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