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. It says nothing about the x402 payment/auth model, rate limits, latency, or what the response contains — none of which the structured fields cover.

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?

A single short sentence, front-loaded and waste-free. It is appropriately sized, though brevity here reflects under-specification rather than precision.

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 no annotations, no output schema, and four undefined overlapping parameters, the description is far too thin for the complexity. An agent cannot determine required inputs, return format, or cost.

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 descriptions are tautological ('Q to process', 'Prompt to process', 'Question to process'), and four overlapping free-text inputs (q, max, prompt, question) are deeply ambiguous. The description makes no attempt to disambiguate which field carries the actual prompt, leaving the agent unable to invoke it correctly.

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 clear verb (ask) and resource (AI assistant) for a general question, so an agent can grasp the basic function. However, it offers no differentiation from the many overlapping siblings such as x402-ai-chat, x402-assistant, and x402-ai-audit, and 'general question' is vague about scope.

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 versus the numerous sibling AI chat/assistant tools, nor any exclusions or preconditions. The agent must guess based on the name alone.

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