set_pinio_box

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

With no annotations, the description discloses the format (UINT8) and default, and explains the disabled value. However, it does not disclose potential side effects, reboot requirements, or behavior on invalid input.

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?

Two concise lines with no redundant information. Every part is essential: purpose, output count, disabled value, type, and default.

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 single-parameter tool with no output schema, the description adequately covers the input format and default. It could mention the order of outputs (1-4) but is otherwise sufficient.

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% but the parameter description is minimal ('Value for pinio_box (UINT8)'). The description adds significant meaning by showing the default format (255,255,255,255) and indicating it is a comma-separated list of four UINT8 values, which the schema does not convey.

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 action (Set) and resource (pinio_box) and specifies it is for AUX box assignments of the 4 PINIO outputs, with the meaning of value 255 (disabled). This distinguishes it from siblings like set_pinio_config.

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 on when to use this tool vs. alternatives such as get_pinio_box or set_pinio_config. The description lacks context for appropriate use cases or conditions.

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