unity_selection_set

Select one or multiple GameObjects in the Unity Editor by specifying their paths or instance IDs.

Instructions

Set the editor selection to specific GameObjects.

Input Schema

TableJSON Schema
NameRequiredDescriptionDefault
pathNoSingle GameObject path to select
pathsNoMultiple GameObject paths to select
instanceIdNoInstance ID of GameObject to select
portNoTarget Unity instance port for parallel-safe routing. Get this from unity_select_instance. When working with multiple Unity instances, ALWAYS include this parameter.
Behavior2/5

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

With no annotations, the description carries full burden for behavioral disclosure. It does not explain whether the selection is replaced or added to, behavior on invalid input, or any side effects. This is a significant gap for a mutation tool.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness4/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is a single, focused sentence that clearly states the tool's purpose. While very concise, it could be improved by adding structure (e.g., describing parameter options).

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness2/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

The tool modifies editor selection with multiple parameters and no output schema, yet the description does not explain return values or conditions for success/failure. It is insufficiently complete for an agent to use correctly.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema coverage is 100% and descriptions are provided for each parameter. The tool description adds no extra meaning beyond the schema, so the baseline score of 3 applies.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description 'Set the editor selection to specific GameObjects' uses a clear verb ('Set') and specific resource ('editor selection'), distinguishing it from the sibling tool 'unity_selection_get' which retrieves the selection.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines2/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

No guidance is provided on when to use this tool over alternatives (e.g., unity_selection_get) or how to choose between parameters (path, paths, instanceId). The schema includes usage notes for 'port' but the description itself offers no context.

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