nina_rotator_stop

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

The description discloses the primary behavior (stopping movement) but omits details like idempotency, blocking behavior, or error states. Since no annotations exist, the description partially fulfills transparency but lacks depth.

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, clear sentence with no wasted words. It is perfectly concise and front-loaded for quick agent parsing.

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 stop action with no parameters and no annotations, the description is minimally adequate. However, it lacks context about return values, when it is safe to call, and potential errors, leaving some gaps for agent decision-making.

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?

No parameters are defined, so schema coverage is effectively 100%. The baseline for 0 parameters is 4; the description adds no further parameter info but does not need to.

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's purpose: stopping rotator movement. It uses a specific verb ('Stop') and resource ('in-progress rotator movement'), distinguishing it from siblings like nina_rotator_move and nina_rotator_info.

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 explicit guidance on when to use this tool versus alternatives. It implies usage when rotator movement is in progress but does not mention safety (e.g., calling when not moving) or provide exclusions.

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