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

Annotations already declare readOnlyHint, openWorldHint, idempotentHint, and destructiveHint=false, covering the safety profile. The description adds only the beta status and the content fields (headlines, descriptions, instructions, provenance), which are more about output content than behavior. It does not add rate limits, auth, or other behavioral traits, so it adds modest value beyond annotations.

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 a single sentence plus a status tag, with no redundant wording. It is appropriately concise, though it could have used the space to explain parameters.

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 tool with two parameters and no output schema, the description provides minimal guidance on how to invoke it correctly. It lacks explanation of the area format, limit semantics, and what 'provenance' means in practice, leaving the agent with insufficient context.

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?

Schema description coverage is 0%, and the description does not explain the 'area' parameter (expected format, e.g., two-letter state code) or the 'limit' parameter (default, behavior). The agent is left to infer from the pattern and min/max, but no semantic guidance is provided.

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 states the tool provides active NWS alerts with headlines, descriptions, instructions, and provenance. This clearly conveys the purpose and differentiates from the basic sibling via the mention of provenance, though it does not explicitly name the alternative.

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 is given on when to use this evidence variant versus the basic sibling. The only extra note is 'FREE beta' status, which does not help an agent choose between tools.

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