Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

With no annotations and no description substance, the agent gets no information about side effects, return behavior, or operational characteristics. The phrase 'Kurtosis Sample' does not disclose any behavioral trait beyond the tool's name.

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 but not effectively concise: it repeats the same phrase with no informative content. This is under-specification rather than purposeful brevity, so it earns no credit for good structure.

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?

Even though the tool takes no parameters, the description gives the agent no idea of what a 'sample' means, what it returns, or why it exists among thousands of similarly named utilities. There is no meaningful context to support correct invocation.

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 tool has zero parameters, so there are no parameter semantics for the description to clarify. The empty schema fully covers the parameter surface, and the baseline for 0-parameter tools is appropriate.

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 is purely tautological: 'Kurtosis Sample: Kurtosis Sample' restates the tool name with no verb, resource, or functional detail. An agent cannot determine what the tool does or how it differs from the hundreds of sibling tools.

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 about when to use this tool, what problem it solves, or when an alternative would be preferable. The description contains no context that would help an agent decide to invoke it.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
