explain

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

The only behavioral trait disclosed is the cost of $0.001 USDC via x402, which is useful but insufficient. Since no annotations are provided, the description must explain what the tool does, whether it is read-only or generative, and any side effects. The agent cannot infer the operation's behavior from this description.

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 extremely brief and front-loaded with the tool name, but the first phrase 'Content & AI tool' is too vague to be informative. The cost information is specific and earns its place, yet the overall structure sacrifices clarity for brevity, making it concise but not effective.

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?

The tool is essentially undefined. With no annotations, no output schema, and a generic params object, the description leaves the agent completely in the dark about the tool's functionality, expected inputs, and outputs. It is far from contextually complete, especially given the wide range of sibling tools.

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 provides only a generic 'params' object with no specific properties or parameter descriptions, and the tool description does not mention any parameters. The agent has no idea what to include in the 'params' object, making correct invocation impossible.

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 labels the tool as a 'Content & AI tool' which is extremely generic and does not specify what it actually explains or how it differs from similar AI tools like summarize, paraphrase, or tldr. The name 'explain' suggests a capability, but the description adds no clarity about the specific resource or action.

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?

No guidance is provided on when to use this tool, what inputs to provide, or how it compares to alternative tools. It only mentions the cost, which does not help an agent decide between this and sibling tools. There is no context for when this tool is appropriate.

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