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?
With no annotations, the description must carry behavioral disclosure, but it only mentions what the tool does not provide (WHOIS/ownership data). It does not state whether the operation is read-only, what is returned, how url/json/zone are processed, or whether anything is mutated. The limitation disclosed is useful but far from sufficient.
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 one short sentence with no filler, and the key differentiator ('without WHOIS or ownership data') is included. It is concise and front-loaded, though its brevity comes at the cost of important context that is penalized under completeness.
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 4 parameters, no annotations, and no output schema, the description is incomplete. It only addresses hostname splitting, leaving url, json, and zone entirely unexplained, and gives no sense of return values. The missing output schema and annotations place the full burden on the description, which it fails to meet.
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%, so the baseline is 3. The description adds no parameter-level meaning beyond loosely mapping to 'host'; it does not clarify how url, json, or zone relate to the operation. The schema already documents each parameter, so the description neither helps nor hurts here.
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 a distinguishing exclusion ('without WHOIS or ownership data'). However, the parameter set (url, json, zone) suggests the tool does far more than split hostnames, so the stated purpose is incomplete and partially mismatched with the actual inputs.
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 given on when to use this tool, what inputs are appropriate, or how it relates to alternatives. The only usage hint is the exclusion of WHOIS/ownership data, which is a data limitation rather than a usage condition. An agent cannot infer when to call it versus a sibling tool.
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.
Several tools operate on URLs and overlap in scope: citation, normalize-url, and domain-shape all accept URL-related input and return overlapping metadata. The compatibility tool is too vague to distinguish from the others, and timezone/utc-time are similarly close.
All tool names use a consistent lowercase-hyphenated style, which is readable and predictable. However, the semantic pattern is mixed: some are verb-noun (normalize-url, validate-json) while others are bare nouns or noun-based (citation, timezone, status-catalog).
With 11 tools, the count is within the typical well-scoped range and not overwhelming. Still, the server feels like a grab bag of unrelated utilities rather than a focused toolkit, so the count is reasonable but not ideal.
The tool surface covers several URL, HTTP, time, and validation basics, but there is no clear overall domain tying them together. Notable gaps exist depending on intent: no DNS, header inspection, or meaningful ISBN validation beyond digit shape; the server name suggests a much narrower focus than what is provided.
