apihealth_check

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

No annotations are provided, so the description carries the full burden of behavioral disclosure. It reveals that an HTTP health check is performed, but it does not disclose timeout behavior, redirects, error handling, authentication needs, side effects, or what constitutes a healthy result. This is a minimal disclosure for a network operation.

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 front-loaded sentence with no filler. Every word earns its place, and the core purpose is immediately visible.

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 is simple with one fully documented parameter, but there is no output schema and no annotations. The description says what the tool does but omits return-value semantics and operational details like timeout or failure behavior, which an agent might need to correctly interpret results.

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 100%, with the only parameter 'url' described as 'URL'. The description adds little beyond what the schema already provides, so the baseline score of 3 is appropriate; it does not introduce format, restrictions, or example values.

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 states a specific operation ('HTTP health check') and resource ('a URL'), so an agent can tell it performs a network health check on a single target. It does not explicitly differentiate from siblings like apihealth_check_many or apihealth_status, but the singular 'a URL' provides some 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?

No explicit when-to-use or when-not-to-use guidance is given, and no alternatives are named. The singular phrasing implies this is for one URL rather than many (apihealth_check_many), but the routing is left to inference rather than stated.

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