Emergency disaster alerts near a hotspot

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

No annotations are provided, so the description must carry the burden. It indicates a read operation fetching text alerts, but does not disclose details like time window, response format, or any limitations. This is minimal but not contradictory.

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 short and front-loaded, but includes some redundancy: the English sentence and Korean sentence say the same thing. The usage example adds value, but the duplicate translation could be trimmed.

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 simple one-parameter tool with no annotations or output schema, the description appropriately conveys the core function and typical usage. It does not describe the return value structure, but that gap is minor for a getter of text alerts.

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 only parameter 'place' has a schema description ('핫스팟 장소명'). The tool description adds little beyond that, just using the term 'hotspot area'. With 100% schema coverage, baseline 3 is appropriate.

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 states it retrieves recent emergency disaster text alerts for a Seoul hotspot area. This is distinct from all sibling tools which cover other location-based data (population, traffic, weather), making the purpose unambiguous.

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 includes a concrete example query ('지금 재난문자 온 거 있어?' - 'Is there a disaster text right now?') that signals when to use this tool. It does not explicitly mention alternatives or when not to use, but the use case is clear.

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