mhs5200_set_waveform

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

Annotations already indicate the tool is mutating but idempotent and non-destructive. The description adds no additional behavioral context beyond the annotations, such as side effects or authentication requirements. It does not contradict 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 and well-structured with an Args section and Returns note. It avoids unnecessary words, though the front-loaded purpose sentence could be slightly more prominent.

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 tool's simplicity and the presence of an output schema, the description adequately covers the tool's behavior and parameters. It clearly explains the allowed waveform values and channel range, making it easy for an agent to use.

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 two parameters (channel and waveform) and their allowed values, which mirrors the information already present in the input schema descriptions. Given that schema description coverage is 0% (though schema actually includes descriptions), the description adds no new semantic value beyond what the schema provides, so a baseline score of 3 is appropriate.

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 'Set the waveform type for a channel,' using a specific verb ('set') and resource ('waveform type for a channel'). This uniquely identifies the tool's function and distinguishes it from sibling tools like mhs5200_set_amplitude or mhs5200_set_frequency.

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 provides clear context for when to use this tool—specifically for setting the waveform type on a channel. However, it does not explicitly mention when not to use it or suggest alternatives, which would improve guidance.

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