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

No annotations are provided, so the description must cover behavioral aspects. It mentions 'operations' implying both read and write capabilities (get/set/toggle), but does not describe side effects, idempotency, or safety implications (e.g., whether toggling AFC affects other settings).

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 a single dense paragraph. It front-loads the purpose and lists operations efficiently, but could benefit from structured formatting (e.g., bullet points) to improve readability. It is not overly long but feels cramped.

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 output schema, 2 parameters (one undocumented), and 14 sibling tools, the description is incomplete. It does not explain return values, error conditions, or the role of the 'value' parameter. The agent lacks critical context to use this tool effectively.

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 schema has 0% description coverage, so the description must compensate. It enumerates valid values for 'operation' in a list, which adds meaning beyond the schema's empty description. However, it fails to describe the 'value' parameter at all, leaving its type and allowed values ambiguous.

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 the tool's domain: fldigi operating controls and status, and lists specific operations. It distinguishes the tool from general-purpose tools but does not differentiate from sibling tools that may also relate to fldigi, such as 'fldigi_call' or 'frequency'.

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 lists operations but provides no guidance on when to use this tool versus alternatives, nor when to use specific operations. Sibling tools are listed but not differentiated, leaving the agent to infer usage context without explicit direction.

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