get_dyn_idle_min_rpm

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

No annotations are provided, so the description must carry the burden of disclosing behavior. The name 'Get' implies a read-only operation, and the description does not contradict this. It adds the data type and range [UINT8, 0–200, default: 0], which is useful, but it does not explicitly state the tool is safe or idempotent. The description is minimally adequate for a simple getter.

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 front-loaded. It contains three short sentences and a bracketed specification, with no filler or redundant information. Every part adds value.

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 getter with no parameters and no output schema, the description provides sufficient context: it explains what dynamic idle is, that setting a non-zero value enables it, the targeting by prop size, and the value's range. Minor omission: it does not explicitly state that the tool returns the current value, but this is implied.

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 has no parameters, so schema coverage is 100% and the baseline is 3. The description adds value beyond the schema by documenting the parameter's data type, range, and default value (UINT8, 0–200, default: 0). This helps the agent understand the nature of the retrieved value.

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 the tool reads the 'Minimum motor RPM maintained by dynamic idle.' It uses the verb 'Get' and identifies the specific parameter. However, it does not explicitly differentiate from other getter tools among the many siblings, relying on the parameter name alone.

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 briefly mentions that setting this value non-zero enables dynamic idle and that it is targeted by prop size, but it provides no guidance on when to use this getter versus alternatives (e.g., set_dyn_idle_min_rpm). There is no explicit 'when to use' or 'when not to use' information.

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