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

With no annotations and no output schema, the description carries the full behavioral burden. It implies a config plus are returned, but says nothing about default values when a setting is omitted, whether the settings are overrides, or what the payment/trial mechanics actually gate.

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?

One front-loaded sentence stating the purpose, with the promo trailing. Tight overall, though the free-trial clause is marketing rather than tool semantics.

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 five-parameter generator with no annotations, no output schema, and 0% schema coverage, the description leaves critical gaps about value formats and defaults. The name and field list give a starting point but not enough to invoke confidently.

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 0% and all five parameters are untyped strings with no enums. The description at least maps its listed settings (semi, quote, tab width, print width, trailing comma) onto the parameters, but gives no valid value formats (e.g. boolean strings, quote style tokens), leaving the agent guessing.

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 names a specific verb and resource ('Builds a Prettier config and its JSON') and enumerates the settings it is derived from. This distinguishes it from the similarly named x402-eslint-config and x402-editorconfig siblings, though it does not explicitly call them out.

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 only routing information is a promo line about free trial calls. There is no guidance on when to build a Prettier config versus an eslint/editorconfig one, or what prerequisites a signed wallet implies beyond the marketing text.

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