get_historical_volatility

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

No annotations are given, and the description does not disclose any behavioral traits such as rate limits, authentication needs, or side effects. The description is minimal and lacks transparency.

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 well-structured. It uses an 'Args' section but lacks a clear separation of description and details. It is concise but could be more organized.

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?

With no output schema and no annotations, the description fails to explain what the response contains or any prerequisites. For a data retrieval tool, more context about the output is needed.

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 description adds brief explanations for each parameter (e.g., category is 'Product type: option'), which adds some meaning beyond the schema. However, with 0% schema coverage, more detail could be helpful.

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 states it gets historical volatility for options, with parameters like category, base_coin, and period. However, it does not distinguish itself from similar data retrieval tools among siblings, which are numerous.

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 vs alternatives. No context about prerequisites or typical use cases is provided.

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