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

With no annotations, the description carries the full behavioral burden, yet it discloses only the x402 payment cost. It says nothing about what the probe does, whether it makes outbound requests, what it returns, or any safety/rate-limit characteristics — exactly the concerns that matter for a probe-style tool.

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 text is short, but it is under-specified rather than concise: the only substantive content is a price tag. Nothing is front-loaded about purpose, which is the primary job of the first clause.

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 callable, paid tool with an undocumented required-in-practice parameter, no output schema, and no annotations, the description supplies essentially none of the information an agent needs. Pricing alone is insufficient to safely invoke it.

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 single parameter "q" has 0% schema description coverage and the description adds no meaning at all — no indication of whether it is a URL, hostname, or query term. This is the critical missing information for invoking the tool 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?

"integration probe" is a vague label that does not state a concrete verb+resource; it neither explains what is probed nor what an integration probe would return. The name hints at SSRF probing, but the description never confirms or clarifies that, and it does not distinguish this tool from the sibling probe-ssrf-3lxWcQ.

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 when-to-use guidance, no prerequisites, and no mention of when not to use it or which sibling to prefer. The only actionable information is the price, which does not help an agent decide whether this is the right tool.

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