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

No annotations are provided, so the description must carry the behavioral burden. It communicates that the tool returns macro-economic events with volatility forecasts and implies an overview-style read-only panel. However, it does not explain what 'Bundle tier' means, how current the data is, or any limitations.

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 short and front-loaded with the main subject. However, 'Bundle tier' is unexplained jargon that slightly reduces clarity; otherwise the sentence is tight and wastes no words.

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?

The output schema covers the return shape, and the zero-parameter schema lowers complexity. Still, the description omits practical context such as when to choose this over get_major_news or get_market_clock, and 'Bundle tier' is not clarified. Adequate but with clear gaps.

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 tool has zero parameters, so no parameter documentation is needed. The empty schema already covers everything, and 'Bundle tier' suggests a fixed bundled output requiring no arguments. Baseline for zero-parameter tools is 4.

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 identifies the resource as high-impact economic events and adds the key differentiator of volatility forecasts, which distinguishes it from news-focused siblings like get_major_news. It lacks an explicit verb, but combined with the tool name 'get', the intent is reasonably clear.

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 instead of alternatives. 'Bundle tier' hints at packaging but not at the appropriate use case. The agent receives no exclusions, prerequisites, or comparisons to sibling tools.

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