set_pid_in_tlm

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 value type and default, but does not mention side effects, persistence, or whether reboot is required. Minimal behavioral context beyond the obvious setter function.

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 informative sentence with a bracketed type/default hint. It is concise and front-loaded with the tool name and action.

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 setter, the description plus schema provide essential info. However, absence of output schema and lack of behavioral transparency (e.g., effect timing, success indication) leaves some gaps. Adequate but not complete.

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 schema already describes the parameter value as a UINT8 string. The description adds the default value ('OFF') and the protocol support qualification, providing meaningful addition beyond the 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 the tool sets pid_in_tlm to include PID data in telemetry output, with protocol support qualification. The verb 'Set' and the specific parameter name distinguish it from get_pid_in_tlm and other set_ tools.

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 implies usage when needing PID data in telemetry, but does not explicitly state when to use this tool versus alternatives or provide conditions for use or non-use. It mentions protocol support but gives no exclusions.

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