afg2125_set_offset

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

The description adds behavioral context beyond annotations, stating that the tool enforces current amplitude and a +/-5V output limit. However, it does not describe what happens on limit violation (clamp, error, etc.) or return behavior. Annotations provide no safety hints, so the description carries some burden but leaves gaps.

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, front-loaded sentence that clearly names the action and the key constraint. Every word contributes to understanding, with no redundancy.

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 simple setter with one parameter, the description is sufficient: it states the action and the critical constraint, and the output schema covers return values. It lacks explicit sibling differentiation, but that is a minor gap given the low complexity.

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?

With one parameter (offset_volts), the schema provides a clear title and type. The description adds no additional semantics beyond tying the parameter to DC offset. The 0% schema description coverage is compensated by the simple, self-explanatory nature of the parameter.

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 action ('Set DC offset') with a distinct resource and behavior. It distinguishes this from sibling set_* tools by focusing on offset while adding the constraint of preserving amplitude and output limit.

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 context (set offset while enforcing constraints) but does not explicitly state when to use versus alternatives like set_amplitude or set_frequency. It provides no exclusion criteria or mention of siblings.

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