Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
The description discloses the non-storage of page content ('Page content is not stored.'), which is a behavioral trait. However, it does not explain other behaviors such as whether the tool performs network requests, handles redirects, or has any side effects. With no annotations provided, this partial disclosure is insufficient for full transparency.
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, consisting of just two short sentences. It conveys the core functionality without any fluff or redundant information. This is ideal for an agent to quickly 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 lacks essential context. It does not explain the tool's relationship to sibling tools, the intended use case, or how the parameters are meant to be used together. The presence of unrelated parameters and the tool name 'citation' (which is not mentioned in the description) creates confusion. The description is far from complete for an agent to use effectively.
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 schema provides descriptions for all four parameters, but they are minimal and largely unrelated to the stated purpose. The description adds no meaning beyond the schema and fails to explain how 'host', 'json', or 'zone' relate to returning host, scheme, and HTTP status. The mismatch between the tool's purpose and the parameters reduces clarity significantly.
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 a specific action ('Return host, scheme, and HTTP status for a URL') and identifies the resource (URL). This distinguishes it from most sibling tools like timezone or validate-json, though it does not explicitly name alternatives. The purpose is understandable without ambiguity.
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?
There is no guidance on when to use this tool versus any of the sibling tools. The description does not mention any conditions, prerequisites, or scenarios where this tool would be preferred over normalize-url, status-catalog, or others. The agent is left without direction on selection.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Add one secure layer between your agents and this server.
Most tools have clear, distinct purposes (e.g., timezone vs. normalize-url). The only minor overlap is between 'timezone' and 'tz-europe-madrid', but they differ in generality (any named zone vs. a fixed zone).
All tool names follow the same lowercase, hyphen-separated pattern (e.g., 'tz-europe-madrid', 'utc-time', 'validate-json'). No mixed conventions or inconsistent verb usage.
11 tools is a reasonable number. The set includes several non-clock utilities (URL, JSON, robots) that broaden scope beyond the server's name, but the count itself is not excessive or too sparse.
For a clock/time server, core operations are covered: UTC time, named timezone, and a specific fixed zone. The 'iana-zones' tool aids discovery, though a full zone list or conversion functionality is missing. Extra web/JSON tools are unrelated but not a defect.
