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

No annotations are supplied, so the description must carry the behavioral burden. It adds real context — the result is a list of *active* alerts delivered 'with instructions' (i.e., response includes guidance text) — but it never says the operation is read-only, what permissions or token tier ('PRO') are required, or anything about freshness/rate limits.

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?

One front-loaded sentence that names the resource, scope, and filters with zero padding. The only questionable token is the opaque 'PRO.' prefix, but it costs almost nothing in length.

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?

Four parameters at 25% schema coverage with no annotations and no output schema means the description should do more. It covers the domain well but leaves the 'PRO'/access_token relationship, allowed min_severity values, and response shape implicit.

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 coverage is only 25% (only access_token is documented), yet the description compensates for the important filters by naming the event dimension with concrete examples ('Tornado', 'Flood', 'Heat') and calling out severity filtering. It stops short of explaining what values min_severity accepts, which matters since there are no enums.

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 resource and scope: active alerts in a given state, optionally filtered by event type and severity. An agent can tell what it returns, but nothing distinguishes it from the sibling weather_alerts tool, which sounds closely related.

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 word 'filterable' implies the optional filters, and 'PRO.' hints at a gated/subscriber tier, but there is no explicit when-to-use guidance, no statement of when not to use it, and no routing versus weather_alerts or sites_check.

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