Return host, scheme, and HTTP status for a URL. Page content is not stored.
| 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 carries the full burden. It only mentions that page content is not stored, but omits crucial behaviors such as redirect handling, error responses, rate limits, or side effects. The agent cannot predict the tool's runtime behavior reliably.
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 short and to the point, but it is incomplete. It lacks a clear structure that maps to the schema, and the single sentence does not cover the full scope of inputs or outputs.
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 sibling tools (normalize-url, validate-json, timezone, etc.), the description does not position this tool within the broader context. It fails to clarify how citation differs from normalization or validation, and the output format is unspecified.
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 includes descriptions for each parameter, but they are generic and conflict with the tool's stated purpose. The description does not explain why 'host', 'json', or 'zone' are inputs for a URL citation tool, leaving the parameter meanings ambiguous and inconsistent.
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 action ('Return host, scheme, and HTTP status for a URL') but does not clarify the role of other parameters (host, json, zone) in the schema. It also fails to distinguish this tool from siblings like normalize-url or status-catalog, which may overlap in functionality.
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 alternatives. The description gives no conditions, prerequisites, or contextual cues to help an agent select it appropriately.
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 clearly distinct outputs: URL metadata, URL normalization, hostname labels, robots inspection, HTTP status catalog, time lookups, JSON validation, and hex encoding. The main ambiguity is between citation and normalize-url, which both return host/scheme information, and between timezone and utc-time, though the descriptions help clarify their different outputs.
All names use lowercase hyphenation, giving a surface-level consistency. However, the set mixes nouns like citation and timezone, verb-object forms like inspect-robots and normalize-url, and the unusual hex-ok, so there is no consistent naming pattern.
With 11 tools, the count is reasonable and within the well-scoped range. The tools span URL, time, and data utility categories without feeling redundant, though the breadth suggests a general-purpose utility server rather than a tightly focused one.
The set covers common URL, time, and simple data-validation needs, but the overall domain is broad and somewhat unclear. Obvious companion operations are missing, such as hex decoding, timezone conversion, or more detailed request inspection beyond the vague compatibility tool.
