Jt Decodes

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

Annotations already cover safety, idempotency, and open-world behavior, and the description adds ordering ('newest first') plus parsed output shape. It does not add permissions, rate-limit, error, or default-time-window context, so the added behavioral value is modest.

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?

It is a single front-loaded sentence with little wasted wording. However, phrases like 'read into its parts' and 'sign-off it carries' are cryptic jargon that reduce immediate clarity.

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?

Rich schema descriptions, annotations, and an output schema reduce what the description must carry, and it does state ordering and output flavor. Still, it omits usage routing against obvious siblings and does not make the default recent window explicit, leaving a meaningful selection 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?

All seven parameters have 100% schema description coverage, so the schema carries parameter semantics. The description only obliquely references CQ calls and does not add band, callsign, SNR, limit, instance, or time-range meaning beyond the schema.

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?

Identifies the resource as 'Recent decodes' with 'newest first' ordering and describes content as CQ or who is calling whom. It is clear but does not explicitly distinguish this tool from siblings such as jt_cq or jt_heard.

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 gives no when-to-use, when-not-to-use, or alternative-tool guidance. With siblings like jt_cq, jt_heard, and jt_wspr present, the agent must infer routing without help.

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