get_esc_sensor_halfduplex

Check whether half-duplex UART is enabled for BLHeli32/AM32 ESC sensor telemetry on a single wire.

Instructions

TDQS

A3.7/5.0
Behavior3/5

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

No annotations are provided, so the description carries full burden. It discloses the tool is a read operation (get), the data type (UINT8), and default (OFF), but lacks details on side effects, rate limits, or other behavioral traits.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is a single sentence plus a parenthetical note, conveying purpose, protocol, compile requirement, type, and default efficiently without unnecessary words.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness4/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For a simple getter of a configuration parameter, the description covers the essential aspects: purpose, protocol, compile dependency, type, and default. No output schema is needed.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters4/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

There are no parameters in the schema, and schema coverage is 100%. The description adds context by explaining what the setting does, which is sufficient for a parameterless tool.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose4/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states the tool retrieves a setting for enabling half-duplex UART for ESC sensor telemetry, specifying the protocol and compile requirement. It distinguishes from other 'get_' tools, though not explicitly from the 'set_' variant.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines3/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description provides a compile-time requirement (USE_ESC_SENSOR) but does not discuss when to use this setting versus alternatives or mention any prerequisites beyond the compile flag.

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