Http Check

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. It states the tool checks status, timings, and redirects but does not disclose whether it makes external network requests, requires authentication, has timeouts, or is read-only. It gives no information about side effects or constraints.

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—a single short line that front-loads the core purpose and key outputs. It wastes no words and is easy to scan. However, it is so terse that it omits necessary details, but the conciseness itself is appropriate.

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 the generic schema and no annotations, the description is incomplete. It does not explain what parameters to provide, how the tool is invoked (e.g., target URL), or what the output structure is despite an output schema existing. An agent would struggle to call it correctly without additional context.

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 is a generic 'params' object with no descriptions (0% coverage). The description does not compensate by explaining what parameters are expected, such as URL, method, headers, or timeouts. An agent cannot determine how to populate the params field correctly from the description.

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 purpose: HTTP(S) check with outputs of status, timings, and redirects. It clearly identifies the resource type and what it measures, distinguishing it from other network tools like tls_check or tcp_connect. However, it lacks an explicit verb like 'perform' or 'test', and doesn't mention how to specify the target, so it's not fully explicit.

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 provides no guidance on when to use this tool versus alternatives. There is no mention of suitable scenarios, exclusions, or comparisons to sibling tools like tcp_connect or tls_check. An agent must infer usage solely from the name and one-line description.

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