Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
The description does not disclose what operations the tool performs on the input parameters. Since no annotations are provided, the tool's behavior is entirely opaque, especially given the mismatched parameter descriptions.
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 very short, but it fails to convey any useful information beyond a vague topic. It is not structured to highlight the tool's purpose or usage, making it too terse to be helpful.
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 tool lacks an output schema and provides no explanation of how parameters relate to the stated purpose. The description is severely incomplete for an agent to understand what the tool does or what it returns.
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 parameter descriptions (url, host, json, zone) are clearly borrowed from other tools (e.g., normalize-url, validate-json, timezone) and do not align with a catalog of HTTP status codes. This makes the parameter meanings confusing and misleading.
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 it is a 'Short catalog of common HTTP status codes,' but this is a noun phrase rather than an action. It does not clarify what the tool actually does with the input parameters, making the purpose unclear.
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 or how to use this tool. There is no mention of alternatives or specific scenarios, leaving the agent to guess its applicability.
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 overlap in purpose: timezone, tz-europe-berlin, and utc-time all return current time, and citation/normalize-url both analyze URL components. 'compatibility' is too vague to distinguish from the other HTTP/classification tools.
All names are lowercase and hyphenated, which is a consistent delimiter style, but the pattern mixes verb phrases (inspect-robots, normalize-url, validate-json) with noun phrases (citation, compatibility, status-catalog). There is no uniform verb_noun or noun_noun convention.
Eleven tools is not excessive in raw count, but the server is named as a clock and only four tools (timezone, tz-europe-berlin, utc-time, iana-zones) support that purpose. The rest are unrelated web/HTTP/JSON utilities, making the set poorly scoped.
For the clock domain, time lookup is covered but timezone conversion is missing. For the broader web/HTTP utilities hinted at by the other tools, the surface is incomplete and lacks a clear lifecycle or workflow, so agents would hit dead ends.
