set_serialrx_halfduplex

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

No annotations present, so description carries full burden. States basic function and default, but fails to disclose behavioral traits like persistence, reboot requirements, side effects on other settings, or safety implications. Lacks depth expected for a mutation tool.

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?

Single sentence plus note, 16 words. Front-loaded with action, zero wasted content. Extremely concise.

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?

Tool is simple (1 param, no output schema). Description covers purpose and parameter details adequately. Minor gap: missing valid values or range for the parameter. Otherwise complete for its complexity.

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?

Schema coverage is 100%, baseline 3. Description adds default 'OFF' and type UINT8, but schema already indicates type string with UINT8. Does not enhance meaning beyond schema, e.g., valid range or common values.

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?

Description clearly states the verb 'set' and resource 'serialrx_halfduplex', explains it enables single-wire half-duplex UART for serial RX, and gives context (some CRSF implementations). It effectively distinguishes from sibling tools like set_serialmsp_halfduplex and set_esc_sensor_halfduplex by specifying the exact purpose.

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?

Implied usage context via 'some CRSF implementations', but no explicit when-to-use or when-not-to-use guidance. Does not mention alternatives or conditions for using this tool over other half-duplex settings.

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