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

With no annotations, the description carries the full burden of behavioral disclosure, but it says nothing about what the tool does, what it returns, or side effects. It does not even state a clear action.

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 it is under-specified and redundant rather than genuinely concise. Every word repeats the tool name without adding useful 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?

Even for a one-parameter tool, the description is inadequate: the agent cannot tell what input format is expected, what operation is performed, or what the output represents. The absence of an output schema raises the need for descriptive context, which is entirely missing.

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?

Schema description coverage is 100% for the single 'value' parameter, though the description 'Value to process' is generic. The tool description adds no parameter meaning, but high schema coverage keeps this at baseline.

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: 'Scientific Notation: Scientific Notation' merely restates the tool name and provides no verb or resource. It does not indicate whether the tool converts to scientific notation, parses it, formats it, or validates it.

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?

The description offers no guidance on when to use this tool or how it differs from any sibling. An agent cannot determine appropriate invocation context from the text.

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