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

No annotations are present, so the description carries the full burden. It discloses the aggregation behavior (combines multiple endpoints), the detailed output fields, and the access requirement (FREE — no API key needed). It doesn't mention data freshness, latency, or explicit read-only-ness, but for a zero-parameter read aggregator this is strong coverage.

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 front-loaded with purpose and a strong recommendation, and the combined-endpoint note is efficient. The return enumeration is long but each item is specific and valuable given the lack of an output schema.

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 is the sole source of runtime expectations. It fully enumerates the return payload, explains how this tool relates to others, and notes the auth requirement. An agent has everything needed to invoke and interpret the response.

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 accepts zero parameters, so there are no parameter semantics for the description to clarify. The baseline of 4 for no-parameter tools applies, and the description appropriately focuses on output rather than 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?

States a specific verb (Get), a clear resource (full market awareness), and explicitly differentiates itself as a composite of /risk + /regime + /events, which distinguishes it from sibling tools like get_risk_index or get_events. The return list further clarifies exactly what the tool provides.

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?

Explicitly recommends this as the FIRST tool for any trading agent and explains that it combines three endpoint categories, implying that individual sibling tools are for single-component needs. However, it does not explicitly state when NOT to use this tool (e.g., if only risk index is needed).

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