hamqth_dx_spots

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

The description adds behavioral context beyond the input schema: it is public, no auth required, updates every ~15 seconds, and notes client-side filtering for the 'call' parameter. These details compensate for the lack of annotations.

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?

Two short sentences with no waste. Purpose is stated first ('Live DX cluster spots from HamQTH'), followed by key behavioral details. Every sentence earns its place.

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?

The description covers the tool's purpose, data source, update interval, maximum results, and filtering options. An output schema exists to explain return values, so the description is adequately complete for this simple 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?

Schema coverage is 100%, but the description adds value: for 'limit', it reiterates max 200; for 'call', it clarifies it matches spotted call or spotter, is case-insensitive, and performs client-side filtering. This goes beyond the schema's parameter descriptions.

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 'Live DX cluster spots from HamQTH' with 'public, no auth required', specifying the verb (spots) and resource (HamQTH). This differentiates it from sibling tools like hamqth_lookup or hamqth_activity, which serve different purposes.

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 live DX spots with context on update frequency (every ~15 seconds) and maximum results (200). It does not explicitly state when not to use it or provide alternatives, but the sibling names offer enough differentiation.

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