set_threshold_voltage

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

There are no annotations, so the description carries the behavioral burden. It discloses the allowed voltage range and gives a practical example, which is useful, but it does not describe side effects, persistence, error behavior, or what happens with out-of-range values.

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 compact sentence that places the resource first, then the critical range, then an illustrative example. Every element earns its place and there is 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 single-parameter setter, the description is close to adequate because the range and example are the main operational details. However, with no annotations and no output schema, it would benefit from an explicit action statement and a note on expected behavior after setting the voltage.

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?

Schema coverage is 0%, but the description compensates well by specifying units (V), the full allowed range (-4.0 to +4.0), and a concrete example. This gives the agent enough meaning for the single 'volts' parameter beyond the bare schema type.

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 identifies the target resource (IO threshold voltage) and the relevant range, and the tool name provides the action 'set'. It is not confused with any sibling tool, though the description itself does not explicitly distinguish it from siblings.

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?

Usage is implied by the resource name and the example value for 3.3V CMOS, which suggests this is used to configure IO logic-level thresholds. However, there is no explicit statement about when to use it versus alternatives, or any exclusions.

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