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

With no annotations, the description carries the full burden. It explains the derivation from SFI/Kp and the return values (per-band rating, explanation, current SFI/Kp), implying a read-only computation. No contradictory or missing behavioral traits are apparent.

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 concise with two paragraphs, front-loading the main action in the first sentence. Every sentence adds value: purpose, derivation context, usage guidance, and return structure. No fluff.

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 parameters and an existing output schema, the description covers all necessary context: it explains the input (current SFI/Kp implicitly from system), the per-band output (rating and explanation), and the additional SFI/Kp values. It is complete for a simple read-only 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 zero parameters, so the baseline is 4. The description does not need to add parameter semantics, and it correctly implies no inputs are required.

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 a specific verb 'Get' and resource 'HF band-by-band propagation outlook', clearly indicating the tool's purpose. It distinguishes itself from sibling tools like solar_alerts or solar_forecast by focusing on current propagation per HF band (160m-6m) using SFI and Kp values.

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 advises 'Useful for deciding which band to operate on right now', providing clear context for immediate use. It does not explicitly exclude alternative tools or state when not to use, but the reference to 'current conditions' implicitly sets boundaries.

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