get_vbat_multiplier

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

No annotations are provided, so the description carries the full burden. It states 'Get' which implies read-only, and describes the returned value type and default, but does not explicitly confirm no side effects or other behavioral traits. Adequate but minimal.

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 extremely concise, containing only one sentence plus a type annotation. It front-loads the purpose and wastes no words. Every part is informative.

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 parameter retrieval tool with no parameters and no output schema, the description provides sufficient context. It explains what the tool does and what the returned value represents. A brief mention of the role in voltage divider configuration could enhance completeness, but not essential.

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 (100% coverage), so baseline is 3. The description adds value by explaining that the tool returns a UINT8 with a default of 1, clarifying the nature of the retrieved value beyond the empty schema.

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 it retrieves the vbat_multiplier parameter, using the verb 'Get' and specifying the resource. It adds context ('Voltage divider ratio multiplier') that distinguishes it from other get_ tools. No ambiguity.

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 does not explicitly state when to use this tool versus alternatives (e.g., set_vbat_multiplier). However, the 'Get' prefix strongly implies a read operation, and the sibling naming convention provides implicit guidance. Some agents might benefit from explicit when-to-use instructions.

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