movel_y

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

No annotations are provided, and the description only states the basic action without disclosing behavioral traits such as whether movement is relative/absolute, safety implications, or error conditions, leaving significant gaps.

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 concise with two short lines, no wasted words, though it could benefit from more structure (e.g., clear sections) without adding length.

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 move tool, the description covers the core function and parameter meaning, but lacks return value info, coordinate system context, and assumes prior knowledge about robot movement.

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 description adds basic meaning to parameters (IP as robot address, distance in meters) beyond the schema's type/title, but with 0% schema description coverage, it only partially compensates and lacks richness.

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 moves the TCP of a specified IP robot along the Y-axis direction, specifying the verb (move) and resource (TCP of robot by IP), and distinguishes it from siblings like movel_x and movel_z.

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 for Y-axis movement but does not provide explicit guidance on when to use this tool versus alternatives like movel or movel_x, nor does it mention any prerequisites or scenarios.

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