util_x402_server_probe

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

No annotations exist, so the description must disclose behavioral traits. It does not state whether the probe is read-only, destructive, authenticated, rate-limited, or what side effects occur (e.g., whether it sends multiple requests to the target server). The term 'probe' implies interaction but lacks detail.

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 a single concise sentence that front-loads the purpose and lists key aspects. However, it omits essential details, making it less efficient for the agent; it sacrifices completeness for brevity.

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?

Given no annotations, no output schema, and a complex free-form parameter, the description is severely incomplete. It fails to explain the output format, how to interpret results, or any behavioral constraints, leaving the agent without sufficient context to use the tool correctly.

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's sole parameter, 'arguments', is an unconstrained object with no documented structure. With 0% schema description coverage, the description should explain what properties are expected or how to form the argument. It provides none, leaving the agent unable to construct valid input.

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 clearly uses the verb 'Probe' and specifies the resource 'x402 server end-to-end', listing concrete sub-activities like discovery, status, tools, reliability, and OpenAPI. This distinguishes it from siblings like util_x402_resource_summary and util_x402_server_audit by indicating a comprehensive, multi-faceted check.

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 versus alternatives such as util_x402_server_audit or util_mcp_server_readiness_report. The description does not mention prerequisites, recommended contexts, or excluded scenarios.

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