Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description carries the full burden. It does not mention the output format (e.g., ISO 8601), how invalid timezone names are handled (error vs. fallback), or any side effects. The behavior is not fully transparent.
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, concise sentence that directly conveys the core function. There is no redundancy or extraneous information.
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 appears simple, but the schema mismatch (three irrelevant parameters) and lack of detail on output or error behavior create significant gaps. The description does not sufficiently explain the schema or the expected usage, especially given the irrelevant fields are present in the schema.
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 input schema contains four parameters: url, host, json, and zone. Only 'zone' is relevant to the description; the other three are unrelated and likely artifacts from another tool. The description does not acknowledge or explain these extra parameters, leaving the semantics of the schema inconsistent with the tool's purpose.
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 that the tool returns the current time in a named IANA timezone, which is specific and action-oriented. However, it does not distinguish itself from sibling tools like 'utc-time' or 'iana-zones', though mentioning 'IANA' provides some differentiation.
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 instead of alternatives such as 'utc-time' or 'iana-zones'. The description only states what it does, not the appropriate context or prerequisites (e.g., knowing a valid IANA timezone name).
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

Some tools have overlapping concerns: citation and normalize-url both parse URLs and return host/scheme, and timezone and utc-time both provide current time. compatibility is also vague, making its relationship to the other tools unclear.
Names are consistently lowercase with hyphen separators and mostly use noun phrases, with a few verb phrases (inspect-robots, normalize-url, validate-json). The pattern is readable but not perfectly uniform.
Eleven tools is within the typical well-scoped range, though the set covers a broad mix of URL, HTTP, time, and JSON utilities rather than a single focused domain.
The set covers common inspection tasks (URLs, robots.txt, HTTP status, timezones, JSON validity), but it lacks deeper operations like URL content retrieval, ISO duration conversion/parsing beyond shape, or more comprehensive HTTP status/request details.
