Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
The description discloses that page content is not stored, which is a meaningful behavioral guarantee. However, it does not mention other side effects such as network requests, caching, or data retention beyond page content, leaving some behavioral aspects implicit.
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, concise sentence that directly states the tool's behavior without unnecessary detail. It is well-structured and easy to parse.
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 description is incomplete for practical use. It does not explain how the parameters relate to each other, why json and zone are included, or how the output is formatted. The context is insufficient for an agent to confidently use this tool, especially given the existence of more targeted siblings.
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?
While the schema provides brief descriptions for each parameter (url, host, json, zone), these descriptions do not align with the tool's stated purpose of returning host, scheme, and HTTP status for a URL. The inclusion of json and zone parameters is unexplained and confusing, making the parameter semantics unclear in the context of the tool's core function.
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 function: 'Return host, scheme, and HTTP status for a URL.' This specifies a concrete action and output, leaving no ambiguity about the primary purpose. The added note that page content is not stored further clarifies the scope.
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 guidance is provided on when to use this tool versus the sibling tools like normalize-url, status-catalog, or validate-json. The description lacks any conditional or comparative context, so an agent cannot determine if this should be preferred over more specialized alternatives.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

Most tools serve clearly distinct purposes (URL, time, JSON, robots, etc.), but 'compatibility' is vague and could be confused with other classifications. Overall, the functions are separable.
Naming conventions are inconsistent, mixing hyphenated phrases (domain-shape, normalize-url) with plain words (citation, timezone), and using both nouns and verbs. This lacks a predictable pattern.
With 11 tools, the count falls comfortably within the typical well-scoped range and does not feel excessive or thin.
The set covers a variety of utilities (URL, HTTP, time, JSON, robots) but lacks a clear cohesive domain, leaving gaps for common web-dev helpers like encoding or hashing. It feels like a random collection rather than a complete toolkit.
