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

Annotations already convey readOnlyHint=false, idempotentHint=true, and destructiveHint=false, and the description does not contradict them. The description adds the coordinate-system context, but it does not disclose behavior such as whether movement is instantaneous, whether the agent must already be in the target room, or what happens for invalid coordinates. The annotations lower the bar, and the description meets it without adding rich behavioral detail.

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?

One compact sentence front-loads the action and then packs the coordinate conventions into a parenthetical. Every part carries useful information, with no filler or repetition of annotation fields.

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 five-parameter movement tool with complete schema coverage and safety-relevant annotations, the description plus schema cover most invocation needs. The main gap is the lack of any mention of constraints or failure behavior, such as boundary limits or room membership requirements, but the operation is simple and idempotent, so this is not a major omission.

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 100%, so the schema already documents each parameter's units and meaning. The description adds the essential origin-at-room-center detail, which is not present in the schema and is needed to interpret x, y, and z correctly. This goes beyond the baseline expected for fully covered schemas.

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 states a clear verb and resource: move to a spot in the room. It also supplies the coordinate frame (meters, origin at room center) and separates this from room-level operations like enter_room or leave_room by targeting an in-room position rather than a room boundary.

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 in-room navigation, but it gives no explicit guidance about when to choose this tool over movement-related siblings such as enter_room, leave_room, or read_room. There are no stated exclusions, prerequisites, or alternative conditions, so an agent must infer the right context from the name and the sentence alone.

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