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

There is a contradiction: the description implies a read-only operation ('Probe'), while annotations set readOnlyHint to false. No additional behavioral context is provided beyond 'Free to call', leaving ambiguity about side effects.

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 concise with two sentences, each serving a distinct purpose (purpose and usage). No unnecessary words.

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 an output schema exists, return values are not required, but the description fails to hint at what the output indicates (e.g., boolean support). Lacks mention of errors, rate limits, or additional context for a simple probing tool.

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 100%, so baseline is 3. The description adds minimal value by explaining 'pass the request payload as a JSON string', but does not detail the structure or expected content of the JSON.

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 states the tool's purpose ('Probe URL for x402 payment support') with a specific verb and resource. However, it does not explicitly differentiate from sibling tools like 'spraay_free' or other probes, relying on the name for distinction.

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?

The description gives usage instructions ('Pass the request payload as a JSON string via the body argument') but does not provide when to use this tool versus alternatives, nor any conditions or exclusions.

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