Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description carries the full burden of explaining behavior. It states the basic function but does not disclose whether the operation is read-only, what output format to expect, or any error behavior.
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 with no unnecessary words or redundant information. It is efficiently structured and easy to read.
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 description lacks essential context: no output schema, no required parameters, no error conditions, and no explanation of how the extra parameters relate to the tool. The mismatch between the description and the parameter schema makes the tool's intended usage unclear.
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 four parameters but only 'zone' aligns with the described timezone purpose. 'url', 'host', and 'json' have descriptions unrelated to the tool's stated function, creating a significant mismatch between the description and the parameters.
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 identifies the tool as returning the current time for a named IANA timezone, which distinguishes it from related tools like utc-time. However, it is phrased as a noun phrase rather than an explicit verb-led instruction and does not mention the sibling alternatives.
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 about when to use this tool versus alternatives such as utc-time or iana-zones. The description implies use for named timezones but does not state conditions, exclusions, or preferred scenarios.
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 distinct purposes, but 'citation' and 'normalize-url' overlap in parsing URLs and returning host/scheme details, while 'compatibility' is vaguely described. Overall, the boundaries are mostly clear.
Names are consistently lowercase and hyphenated, but mix noun-style names ('timezone', 'citation') with verb-style names ('inspect', 'normalize', 'validate'). There is no uniform verb_noun pattern, making the naming style inconsistent.
With 11 tools, the count is reasonable for a utility-focused server and within the typical 3-15 range. Each tool addresses a distinct aspect, though some could be consolidated.
The set covers URL parsing, HTTP status, timezones, robots.txt, language tags, and JSON validation, but lacks broader web-development utilities like DNS lookups or header inspection. The domain is not fully defined, so some gaps are possible.
