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

With no annotations, the description carries the behavioral burden and largely meets it: it discloses the audit scope, the dimensions checked, and the returned score/verdict/issues format. It does not discuss rate limits, authorization, or side effects, but 'audit' and the listed checks imply a non-mutating operational probe.

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 compact and front-loaded with the core action. Every sentence adds value, and the sample call is a practical, low-cost addition rather than filler.

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?

The tool has a minimal schema, no output schema, and no annotations, so the description is the main source of context. It covers inputs, checks, and output well, but lacks guidance on when to use it, method-specific semantics, and any access or rate considerations, leaving noticeable gaps.

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 description coverage is 0%, so the description must explain both parameters. It clarifies 'url' as the target agent/API, but 'method' is only implied by the sample call and the schema default. Accepted values, required format, and behavior across methods are left undocumented.

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 names a specific action ('operational audit'), a clear resource ('public agent or paid API'), and enumerates the concrete checks performed. It also states the output score, verdict, and issues, making the tool's goal unmistakable and well differentiated from the broad sibling list.

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 does not explain when to choose this tool over siblings such as probe, read_web_page, or x402_echo. It gives a sample endpoint but no conditions, exclusions, or comparisons to alternative tools, leaving usage decisions to inference.

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