set_channel

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

With no annotations, the description must carry the behavioral disclosure burden. It implies a write operation but does not mention side effects, required permissions, reversibility, or any destructive behavior. The agent has minimal insight into the tool's effects.

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 sentence that is front-loaded with the core action and parameters. Every word serves a purpose; there is no fluff or redundant information.

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 the generic input schema and lack of annotations or output schema, the description is incomplete. It does not specify return values, error conditions, or how the parameters map to the generic kwargs object. An agent would struggle to use this tool correctly without additional context.

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 input schema uses generic args/kwargs with 0% coverage, so the description partially compensates by listing parameter names (enable, V/div, offset, coupling). However, it lacks types, constraints, defaults, or order, leaving significant ambiguity for agent invocation.

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 purpose: setting vertical configuration (enable, V/div, offset, coupling) for a channel. The verb 'set' and resource 'channel' are specific, and the listed parameters differentiate it from sibling tools like set_timebase or set_trigger. However, it lacks mention of how to specify which channel, which is a minor gap.

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 guidance is provided on when to use this tool versus alternatives. The description does not state prerequisites, context, or trade-offs among siblings, leaving the agent without decision-making support.

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