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

With no annotations, the description carries the disclosure burden. It usefully discloses that the catalog is FREE and explains what it contains, but it does not describe the output shape, size, or whether this is a read-only lookup. Acceptable for a zero-parameter list tool, but not fully transparent.

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, high-signal sentence: FREE, full catalog, paid services, prices in USD, and payment methods. No filler or redundancy.

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 no-input catalog tool, the description adequately conveys what the agent will get: services, prices, and payment instructions. It slightly under-specifies the response format or length, but the low complexity and absent parameters make this a minor gap.

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 input schema has no parameters, so there is nothing to explain beyond the schema. The zero-parameter baseline of 4 applies, and the description avoids inventing unnecessary parameter details.

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?

States a specific deliverable: a full catalog of paid KHOTEM services with USD prices and payment methods (x402 direct, USDC on Base). This is immediately distinguishable from sibling action tools like khotem_attest or khotem_seal.

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 usage context is clear: call this tool when you need the full list of paid KHOTEM services, their prices, or how to pay. It does not explicitly name alternatives or exclusions, but the catalog role versus verification/action siblings is evident.

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