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

With no annotations provided, the description carries the full behavioral burden; it usefully discloses data provenance, source thresholds such as USGS M5.0+, and that events are active or recent. It still omits operational details such as refresh cadence, temporal window for "recent," pagination or result limits, and any authentication or rate-limit behavior.

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 the core action and resource, then adds source coverage and return fields efficiently. The final sentence explains the use case without wasteful repetition, and every sentence contributes useful context.

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?

For a zero-parameter tool without an output schema, the description does a good job covering sources, event types, returned fields, and intended use. It could be more complete by clarifying how far back "recent" extends and whether the response is capped or paginated.

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 input parameters, so parameter semantics are not applicable and the baseline score is 4. The description appropriately does not invent parameter meanings where none exist.

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 and resource ("Get real-time natural disaster alerts") and enumerates the data sources and event types, so the agent knows exactly what is returned. It does not explicitly differentiate itself from sibling tools such as get_disaster_events or supply_chain_disruption_alerts, which prevents a 5.

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 gives a clear use case for logistics and procurement teams, which implies when the tool is relevant. However, it offers no explicit when-to-use/when-not-to-use rules and does not name alternative disaster or supply-chain alert tools that an agent should choose instead.

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