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

With no annotations provided, the description carries the full burden of behavioral disclosure, and it discloses nothing beyond restating the name. An agent cannot tell whether this is a read-only computation, whether it requires network access, what it returns, or what side effects (if any) exist.

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 short, but this is under-specification rather than conciseness—there is no front-loaded information because there is no information at all. Every other dimension is starved by this 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?

For a technical tool with no annotations, no output schema, and two ambiguous parameters, the description is completely inadequate. An agent has no idea what input to supply, what result to expect, or how to distinguish this tool from any other x402-* utility.

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 nominally 100%, but both parameter descriptions are placeholder-level: 'Key to process' and 'Input to process' convey no real semantics—what kind of key, what format, and how key and input relate remain unknown. The tool description adds nothing on top, and neither parameter is required, leaving an agent unable to construct a correct invocation.

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 'Ssh Fingerprint: Ssh Fingerprint' is a pure tautology—it restates the tool name with zero added meaning. It contains no verb, no resource, no outcome, and no indication of whether the tool computes, fetches, or validates an SSH fingerprint.

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 whatsoever on when to use this tool, what problem it solves, or how it differs from the ~1,000 sibling tools. No alternatives are named, no exclusions given, and no context is provided.

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