get_forecast_today

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

No annotations are provided, so the description carries full burden. It lists output contents (rating, expected high/low, regime context, key events) but does not disclose behavioral traits such as whether the operation is read-only, data freshness, authentication requirements, or potential side effects.

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 very concise, using bullet points to separate products and outputs. Every sentence adds value without redundancy.

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 the simplicity of the tool (one parameter, no output schema), the description adequately covers the return values: rating, expected high/low, regime context, and key events. It is sufficient for an AI agent to understand the tool's output.

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 schema has one optional parameter 'product' with default 'ES' and no description (0% coverage). The description adds meaning by listing supported product values: ES, NQ, MES, MNQ, SPX, SPY, QQQ, which guides the agent on valid 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 clearly states the tool retrieves today's volatility forecast with a rating and expected move ranges, listing supported products. It implicitly distinguishes from sibling tools like get_forecast_week by specifying 'today', but does not explicitly differentiate from other daily forecasts like get_pulse or get_direction.

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 versus alternatives such as get_forecast_week, get_direction, or get_regime. The description does not mention cases where this tool is preferred or not, nor provide when-not-to-use criteria.

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