solar_alerts

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

No annotations are provided, so the description alone conveys the tool's read-only nature (no side effects). It lists the types of alerts and the return structure, which is sufficient for a simple retrieval tool but does not disclose any potential rate limits or freshness of data.

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 three concise sentences: the first states the main purpose, the second lists examples, and the third describes the return value. No redundant information, and it is well-structured.

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 the tool's simplicity (no parameters) and the existence of an output schema (which defines return values), the description is complete enough. It specifies the output fields (product ID, issue time, message text). Could add details on data freshness or pagination, but not necessary for this straightforward tool.

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 no parameters (0 params), so the baseline is 4. The description appropriately focuses on the purpose and output, requiring no additional parameter clarification.

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 the tool's function: 'Get active NOAA space weather alerts and warnings.' It uses a specific verb ('Get') and resource ('active NOAA space weather alerts'), and lists examples of alert types, distinguishing it from siblings like solar_conditions and solar_forecast.

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 implies usage for retrieving current alerts and warnings, but does not explicitly state when to use this tool over alternatives or provide any exclusions. It is clear for its intended use but lacks comparative guidance.

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