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

No annotations are provided, so the description carries the full burden of behavioral disclosure. It reveals nothing: no formula (future value vs. present value), no expected output format, no units, and no relationship between the six inputs. An agent cannot predict what this tool does beyond guessing from the name.

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 short only because it is empty of content; 'Inflation Adjust: Inflation Adjust' is redundant duplication of the same phrase. This is under-specification and tautology, not earned conciseness.

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 six parameters, no output schema, and no annotations, the description needed to explain the calculation semantics, parameter roles, and return value. It explains none of them, leaving the agent unable to construct a valid call or interpret the result.

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?

Although schema coverage is nominally 100%, every parameter description is a meaningless placeholder ('N to process', 'Rate to process') that conveys no units, defaults, constraints, or relationships. The tool description adds nothing to disambiguate confusing overlaps such as n vs. years or value vs. present, and all six parameters are untyped strings with none required.

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 'Inflation Adjust: Inflation Adjust' is a pure tautology that restates the tool name and title, providing no verb, resource, or function statement. It does nothing to distinguish this from closely related siblings such as x402-inflation-adj, x402-purchasing-power, or x402-real-rate.

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?

The description contains zero guidance on when to use this tool versus its many financial siblings. Given the near-duplicate sibling x402-inflation-adj and overlapping tools like x402-purchasing-power, the absence of any routing context is a significant gap, though the text is not actively misleading.

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