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

No annotations are present, so the description carries full responsibility for behavioral disclosure. It reveals nothing about the effects of dock, pickup, drop, or roll, whether the operations are safe, what preconditions exist (e.g., cube must be nearby), or what the robot will do after each action.

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 efficient sentence with no redundant words. It clearly identifies the target resource, which earns its place, though it sacrifices substance for brevity.

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 one-parameter tool the description is not complete enough. It fails to explain the semantics of each enum value, expected side effects, or any prerequisites, and there is no output schema to clarify what the tool returns. An agent would need to guess at the behavior of physical cube actions.

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 description coverage is 100% for the single 'action' parameter, including an enum and a basic description. The tool description adds no additional meaning beyond what the schema already provides, so the baseline of 3 applies.

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 identifies the resource ('Vector's cube accessory') but uses the vague verb 'Interact' instead of naming specific operations. It does not distinguish this tool from siblings like vector_lift or vector_head, so an agent must rely on the schema to infer what the tool actually does.

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 is given about when to use this tool versus alternatives. With 23 sibling tools covering physical actions, the description provides no context for choosing vector_cube over tools like vector_drive, vector_lift, or vector_head.

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