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

With no annotations, the description carries the full burden, and it discloses only that the call is paid ($0.006 USDC per call via x402) — genuinely useful cost/auth context. It says nothing about what the probe actually does, whether it makes outbound requests on the caller's behalf, safety implications, rate limits, or what a result looks like.

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?

It is one short fragment with no wasted words, and the billing note is clearly bracketed and easy to spot. Brevity here reflects under-specification rather than tight editing, but the text itself contains nothing extraneous.

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 paid, unannotated, single-param security-probing tool with no output schema, the definition supplies almost nothing an agent needs. The ambiguous "q" parameter, the absence of any output expectation, and the missing purpose detail all remain unresolved.

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 coverage is 0% and the single parameter is an opaque "q". The description does not say whether q is a URL, hostname, IP, or payload, which is precisely the meaning an agent needs to invoke this 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?

"ssrf probe" essentially restates the tool name and gives no subject, target, or action detail — an agent cannot tell whether it probes a URL, a host, or a parameter for SSRF. The only concrete content is pricing metadata, not purpose. No differentiation from siblings such as liminal-http-headers or liminal-url-to-text is offered.

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 alternatives among the many sibling URL/DNS/HTTP tools. The agent is left to infer entirely from the name that this is a security probing endpoint.

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