monitor_motion_state

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

No annotations are provided, so the description carries full responsibility. It only states the tool monitors and returns state and readiness, without disclosing behavior like whether it is a continuous stream or a one-shot query, whether it blocks, or if it requires any system state. This is insufficient for a transparent behavioral understanding.

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 extremely concise with two short sentences. It is front-loaded with the purpose in the first line. Every word is necessary and no filler is present.

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 the tool has no parameters and an output schema exists, the description need not detail return values. It adequately describes the core function. However, it could mention any side effects or dependencies, but for a simple monitor tool, this is acceptable.

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?

The tool has zero parameters, and schema coverage is trivially 100%. The description adds no parameter information, but the baseline is 4 per the rubric. The description correctly indicates no inputs are needed.

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: 'Monitor current motion state.' The verb 'monitor' and resource 'motion state' are specific. Among sibling tools, 'monitor_motion_state' is distinct from other monitor tools (e.g., 'monitor_localization_state', 'monitor_mrm_state'), making its purpose unambiguous.

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 provides no guidance on when to use this tool versus alternatives. It does not mention prerequisites, conditions, or scenarios where this tool is preferable. For a tool with many sibling monitor tools, such guidance is important.

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