Split a hostname into labels without WHOIS or ownership data.
| Name | Required | Description | Default |
|---|---|---|---|
| url | No | HTTPS URL to normalize or cite | |
| host | No | Public hostname | |
| json | No | JSON text to validate; discarded after the check | |
| zone | No | IANA timezone name |

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 discloses that WHOIS/ownership data is not included, but it does not state what happens with invalid input, whether other schema parameters are ignored, what output is returned, or any side effects.
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, tight sentence with no wasted words and the core action is front-loaded. The exclusion of WHOIS/ownership data is useful context and does not add fluff.
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?
For a tool with four optional parameters, no output schema, and no annotations, the description is too sparse. It leaves the agent without clear invocation guidance, expected return format, or behavior for edge cases, making it incomplete for reliable selection and use.
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?
Although schema description coverage is 100%, the parameter descriptions for url, json, and zone appear unrelated to splitting a hostname into labels. The description adds only the term 'hostname,' which weakly maps to the 'host' parameter, but it does not clarify which parameters are actually relevant or how they are used.
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 verb and resource ('Split a hostname into labels') and qualifies the scope by explicitly excluding WHOIS or ownership data. This gives the agent a clear core function, though it does not explain the role of the unrelated-looking input parameters.
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 implies the tool is not for WHOIS/ownership lookups, but it provides no explicit when-to-use guidance, no alternatives, and no indication of how it relates to sibling tools like normalize-url, citation, or validate-json. An agent cannot confidently decide when to choose this tool over a sibling.
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 target distinct resources like URLs, hostnames, robots.txt, timezones, and JSON. The main overlap is between citation and normalize-url, which both expose host information from a URL, and between timezone and utc-time when the requested zone is UTC. Descriptions are generally clear enough to disambiguate.
All names use lowercase-with-hyphens, but the pattern is mixed: some are verb-object like normalize-url and validate-json, while others are nouns like citation, timezone, and status-catalog. This is readable but not a consistent verb_noun convention.
11 tools is within a reasonable range for a utility server, and each tool has a distinct small purpose. A few could be consolidated, such as utc-time with timezone or citation with normalize-url, but the count is not excessive.
The server covers basic URL inspection, time retrieval, JSON validation, and word counting, but notable gaps exist such as URL validation, timezone conversion, HTTP header inspection, and JSON formatting. The surface is more of a grab bag than a coherent full-featured utility domain.
