Netlogger Set Callsign

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

No annotations are provided, so the description carries the full burden. It usefully explains why the call is required (NetLogger identifies the station on every request), but does not disclose persistence, whether a repeat call overwrites the prior value, or error behavior for an invalid callsign. Return values are covered by the output schema, so that gap is acceptable.

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?

Three short sentences, front-loaded with the action and the 'needed once, before the first lookup' constraint. Every sentence carries information; nothing is restated from the schema.

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 one-parameter configuration tool with an output schema and full schema coverage, the description supplies the missing pieces: necessity, ordering relative to other calls, and argument sourcing. Only the overwrite/repeat-call behavior is left unspecified, a minor gap.

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%, so the baseline is 3, and the description adds genuine value by telling the agent the value must come from the user rather than be inferred or guessed. It does not add format/validation rules beyond the schema's example (KI7MT), which keeps it just short of the top score.

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?

States a specific verb ('Save') and resource ('the user's amateur radio callsign'), which cleanly separates it from the read-only lookup siblings (netlogger_active_nets, netlogger_checkins, etc.). An agent can identify this as the one write/configuration tool in the set without opening any schema.

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?

Explicitly states the timing and necessity: 'Needed once, before the first lookup,' plus a directive on value sourcing ('Ask the user for their own callsign; don't guess it'). This gives the agent both when to call it and how to obtain the argument, with no ambiguity.

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