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

No annotations exist, and the description reveals zero behavioral traits. It does not mention outputs, side effects, prerequisites, or anything that would help an agent understand what calling this tool entails.

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 minimal to the point of being under-specified rather than concise. It contains no substantive content, so brevity here is not a virtue.

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?

For a tool with no output schema and no annotations, the description is the only source of semantics, and it is completely empty. An agent cannot determine what a 'margin of error' operation would return or when to invoke it.

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 has zero parameters, so the baseline for this dimension is 4. There is nothing for the description to clarify parameter-wise, though the description also adds nothing meaningful about inputs.

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 'Margin Of Error: Margin Of Error' is a pure tautology—it restates the tool name without any verb, resource, or behavior. It provides no information about what the tool does or how it differs from the many 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?

There is no guidance on when to use this tool versus alternatives. No context, exclusions, or sibling references are provided, leaving the agent to guess entirely.

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