get_pinio_box

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

The description explains the output format and default values, adding value beyond the schema. It discloses the operation is read-only with no side effects mentioned, which is appropriate for a getter. No annotations exist to contradict.

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-sentence description is concise and front-loaded: first sentence states purpose, second provides technical details (default and disabled meaning). No wasted words.

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?

Given no output schema, the description adequately defines the return format (4 UINT8 values) and semantics. It is complete for a simple getter but could mention response structure (e.g., array) for clarity.

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?

Input schema has zero parameters, so baseline is 4. The description adds meaning about the output (4 UINT8 values, default 255), compensating for the lack of output 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?

Description clearly states it retrieves pinio_box assignments, specifying 'AUX box assignments for the 4 PINIO outputs' and explaining the meaning of 255 as disabled. This is specific and distinguishes it from sibling tools like set_pinio_box.

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 as a getter (verb 'Get') but does not explicitly state when to use it versus alternatives. Since it's a simple read, the implicit context is adequate but not proactive.

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