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

No annotations provided, so description carries full burden. It discloses that it's a public endpoint without authentication, but does not mention idempotency, rate limits, or data freshness. One behavioral aspect is disclosed, but more would be beneficial.

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 sentences, zero wasted words. The most important information (what it does, inputs, auth requirement) is front-loaded. Text is highly scannable.

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?

Tool is simple with one parameter and an output schema. Description covers purpose and auth requirement. For a simple resolver, this is nearly complete. Missing details like error handling or output format are likely covered by output schema.

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 100% for the single parameter, and the description verbatim matches the schema's description. No additional semantics or examples are added beyond what the schema already provides.

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?

Description clearly states the tool resolves a DXCC entity from a callsign or ADIF entity code. Verb and resource are specific, and it distinguishes from sibling tools like hamqth_lookup and hamqth_dx_spots by focusing solely on DXCC entity resolution.

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 explicit when-to-use or alternatives provided. The phrase 'Public endpoint — no authentication required' implies it's safe and accessible, but lacks guidance on when to prefer this over siblings like hamqth_lookup or hamqth_dx_spots.

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