get_forecast_week

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

No annotations provided, so description carries full burden. It implies a read-only operation ('Get'), but does not disclose side effects, rate limits, authentication needs, or what the forecast contains beyond 'volatility'. Basic transparency, but minimal.

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 two succinct sentences: one for purpose, one for parameters. No unnecessary words. Information is front-loaded and easy to parse.

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 no output schema, the description doesn't describe the return format or contents of the forecast. While the purpose and parameters are clear, the agent lacks full context on what it will receive, which is a gap for a tool with 2 parameters and no schema.

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 has 0% description coverage. The description adds the list of valid products for the 'product' parameter and specifies the YYYY-MM-DD format and optionality for 'date'. This compensates well for the missing schema descriptions, though it doesn't explain default behavior when date is null.

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 the tool retrieves a 5-day forward volatility forecast, specifying the resource (forecast_week) and verb (Get). It lists supported products, distinguishing it from siblings like get_forecast_today.

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 explicit guidance on when to use this tool versus alternatives like get_forecast_today or get_calendar. The product list implies usage for those symbols, but lacks context on use cases or exclusions.

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