mhs5200_set_power_amp

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

Annotations indicate idempotentHint=true and destructiveHint=false, which the description does not contradict. The description adds that the tool returns a JSON confirmation of the power amp state and notes model dependency, providing context beyond the 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?

The description is concise, structured with a note and args/returns breakdown, every sentence adds value, and no information is redundant or missing.

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 tool with output schema (returns JSON), the description covers purpose, parameter, return, and a model caveat. It is complete enough for an agent to use correctly.

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 description lists the 'enabled' parameter and its type/meaning, but the input schema already describes the same parameter. With schema description coverage stated as 0%, the description partially compensates by restating the parameter semantics, but adds no new information.

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?

Description clearly states the tool enables or disables the internal power amplifier, a specific action on a specific resource. It distinguishes itself from sibling tools like set_amplitude or set_frequency by focusing solely on power amp control.

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 includes a note about model dependency ('Not all MHS-5200A models have this feature'), which is helpful but does not explicitly indicate when to use this tool over alternatives or provide exclusion criteria. Usage guidance is minimal.

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