get_use_vbat_alerts

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 adds that the value is a UINT8 with a default of ON, which is helpful, but does not explicitly state that it is a read-only operation or describe any side effects. The 'Get' verb implies read-only, but behavior is only partially disclosed.

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 a single sentence plus a type annotation, efficiently conveying purpose and value type. It is front-loaded with the key action and contains no fluff.

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 output schema, the description explains the purpose and value type. It lacks details on the return format or potential error conditions, but is reasonably complete given the tool's simplicity.

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 empty (0 parameters), and schema description coverage is 100%. The description does not need to explain parameters, but it adds value by noting the return type and default, which is beyond the schema's scope. Baseline 4 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 this tool retrieves the setting for enabling voltage-based OSD/beeper warnings. It specifies the verb 'Get' and the resource 'use_vbat_alerts', and distinguishes it from sibling tools like 'set_use_vbat_alerts' (setter) and 'get_use_cbat_alerts' (current-based alerts).

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?

No guidance is provided on when to use this tool versus alternatives like 'set_use_vbat_alerts' or 'get_use_cbat_alerts'. Being a simple getter, context is minimal, but explicit usage direction is absent.

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