m8811_set_current

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

The description reveals that the tool both sets the current limit and verifies by read-back, giving insight into its behavior. Since annotations already mark this as a mutating, non-destructive operation, the added verification detail improves transparency. It does not state what happens if output is on, but this is minor given annotations.

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?

A single 18-word sentence that includes purpose, precondition, and verification; no filler.

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 one-parameter setter with an output schema, the description covers the what, when, and verification behavior, making it fully adequate.

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 only defines current_a as a number with no description. The description compensates by stating the valid range '0-5 A' and implicitly the unit (amperes), making the parameter's intended value clear.

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 uses a specific verb ('Set'), identifies the resource ('current limit'), and adds scope ('0-5 A'), clearly distinguishing it from sibling setters like m8811_set_voltage and m8811_set_output.

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?

It specifies the precondition 'while output is off', which tells the agent when the operation is valid. It does not explicitly name alternatives or exclusion cases, but the context is clear enough for selecting this tool among siblings.

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