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

The annotations provide 'readOnlyHint: true', but the description adds no additional behavioral context such as data freshness, geographic scope, or alert types. The description carries minimal burden but still fails to inform beyond the annotation.

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 extremely short (one phrase), which is under-specified rather than concise. It does not leverage the available space to provide helpful details.

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?

Given no output schema and only two parameters, the description should clarify what alerts are returned (e.g., active alerts, severity, source). The lack of such information makes the tool definition incomplete.

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 lat/lon parameters or their expected format/range. The parameters are standard but still require clarification for correct invocation.

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 'weather alerts for a location' which conveys the basic purpose, but it does not differentiate from the sibling tool 'weather.current' and lacks specificity about what types of alerts are included.

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 on when to use this tool versus alternatives like 'weather.current' or other alert sources. The description does not mention any context or prerequisites.

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