dmm_set_function

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

No annotations are provided, so the description carries the full burden of behavioral disclosure. It states that the function is set and lists valid values, but it does not say whether switching functions resets range, interrupts a measurement, or has any other side effect.

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 short and front-loaded, with the purpose stated first and a compact argument list following. Every sentence earns its place with no filler or 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 one-parameter setter, the description supplies the purpose and all valid inputs, and an output schema exists to handle return-value expectations. It is slightly incomplete only because it omits sequencing context relative to the other DMM tools.

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 is a bare string with 0% description coverage and no enum. The description fully compensates by exhaustively listing all accepted values (VOLT:DC ... CAP), which is the essential semantic information needed to call the tool correctly.

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 states a specific action ('Set') and a clear target ('the measurement function on the multimeter'), and it enumerates the valid function values. This makes the tool's purpose distinct from sibling setters like dmm_set_range and dmm_set_resolution.

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?

There is no guidance on when to use this tool versus alternatives, no prerequisites, and no mention of related tools such as dmm_get_function or dmm_read. The agent must infer usage purely from the tool name and the generic 'Set' statement.

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