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

No annotations are provided, so the description must fully disclose behavior. It discloses guaranteed max staleness, server-side enforcement, price, and that it is not a prediction. It does not cover authentication or rate limits, but for a read-only tool this is adequate.

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 clear and front-loaded but contains redundant phrases (e.g., emphasizing 'nothing newer than 60 seconds' multiple times). It could be more concise without losing key information.

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 description explains the return format (identical to live tier, same fields and verification block) but does not cover error handling, pagination, or parameter details. With 3 params and no output schema, it is moderately complete.

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 input schema has 3 parameters (limit, since, payment_signature) with 0% schema description coverage. The tool description does not explain any parameter, leaving the agent to guess their semantics. This is a critical gap.

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 identifies the tool as returning verified POTUS statement events with a 60-second recency constraint, distinct from siblings like sygnl47_events_15m and sygnl47_events_live. It includes pricing and emphasizes it is not a prediction.

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?

The description states its own properties (recency, price) but lacks explicit guidance on when to use it over alternatives. It does not mention exclusions or prerequisites, though the fact it is priced and has a recency limit implies it is for recent verified events.

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