| Name | Required | Description | Default |
|---|---|---|---|
| url | No | HTTPS URL to normalize or cite | |
| host | No | Public hostname | |

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations provided, the description carries the full burden of behavioral disclosure. It does not state what the tool returns, side effects, or any requirements, and the vague wording does not clarify operation.
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 single sentence is concise but under-specified rather than efficiently informative. It omits critical context and fails to front-load any actionable detail.
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 four parameters, no output schema, and no annotations, the description is entirely inadequate. It does not explain the tool's purpose, how parameters are used, or what the response will be, making it impossible for an agent to use correctly.
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?
Although the schema provides descriptions for each parameter (100% coverage), the tool description adds no meaning to how they relate. The claim of timezone names conflicts with the presence of url, host, and json parameters, making the semantics confusing rather than clarified.
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 'Common IANA timezone names for clock calls' implies a reference list but the input schema includes url, host, json, and zone, which suggests a different operation. It lacks a specific verb or resource and does not distinguish from sibling tools like timezone or utc-time.
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 on when to use this tool versus alternatives. It does not mention any conditions, exclusions, or sibling tools, leaving the agent without direction.
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 (URL inspection, time, status codes, JSON validation), but citation and normalize-url both deal with URL parts and could cause confusion. compatibility is also somewhat vague, though it appears to classify requests differently.
All tool names use lowercase with hyphens (e.g., domain-shape, utc-time, validate-json), forming a consistent and predictable pattern across the entire set.
11 tools is within a reasonable range, but the server lacks a unified focus—it's a grab bag of utilities. While not excessive, the count feels high for the apparent scope, which is unclear and fragmented.
There is no coherent domain to assess completeness against. The server is labeled 'Language es' but only one tool (lang-es) relates to language, leaving many potential gaps. For a general utility server, it's missing obvious pairs like URL fetching or timezone listing beyond common names.
