set_pen_positions

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

No annotations exist; description provides minimal behavioral info. It implies motion ('MOVE'), but does not disclose side effects, required permissions, or device implications beyond requiring a confirm_token.

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?

Description is short but under-specified. The cryptic code string does not aid clarity and wastes space. Overly minimal for an 8-parameter tool.

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 complex (8 parameters, no output schema, no annotations) yet description offers almost nothing. Return values, error cases, and parameter interactions are completely missing.

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 0% and description adds no parameter meanings. Agent has no understanding of what values like 'accel', 'pen_pos_up', or 'pen_delay_down' represent.

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 in Portuguese states it adjusts pen positions/forces, but the inclusion of cryptic code 'arm_motion('set_pen_positions',{})+token' confuses the purpose. No explicit differentiation from sibling tools like 'test_pen_toggle' or 'calibrate_pen_paper'.

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 versus alternatives. No prerequisites, exclusions, or context provided.

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