Arrange plate

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

Adds substantial behavior beyond the annotations: this is an async job requiring polling via get_job_status until idle, and it re-packs objects across every unlocked plate and deletes plates left empty. That last side effect sits in mild tension with destructiveHint=false, though no object data is actually destroyed, so it reads as disclosure rather than contradiction. It stops short of saying what the returned result reports or how long the job typically runs.

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?

Three sentences, zero filler: the operation and its async/polling nature are front-loaded, the multi-plate side effect follows, and the routing hint to transform_object closes it out. Every clause carries information an agent would otherwise have to discover by trial.

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?

With no parameters, no output schema and only minimal annotations, the description carries the full explanatory burden and does so: it covers the async polling requirement, the scope of the re-pack, the destructive-to-layout side effect, and the correct sibling for the narrower task. Nothing needed to invoke it correctly is absent.

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 takes no parameters, so per the rubric this is a baseline 4; the description correctly omits parameter talk and instead spends its words on behavior. Nothing parameter-related is missing or misleading.

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?

States a specific verb+resource ("Auto-arrange all objects on the plate") and immediately distinguishes itself from the single-object sibling by naming transform_object. An agent can tell what this does and what it is not without opening any schema.

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?

Gives an explicit alternative and the condition that selects it ("To shift one object, use transform_object instead"), plus a warning about the multi-plate case where the operation becomes OrcaSlicer's "Arrange all" and undoes a one-part-per-plate layout. That is clear when-to-use and when-to-avoid guidance.

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