batch_transform

Apply identical translation, rotation, or scale to multiple objects simultaneously, with option for relative or absolute transforms.

Instructions

Apply the same transform to multiple objects at once. Translate is [x,y,z], rotate is [x,y,z] in degrees, scale is [x,y,z]. If relative=True, transforms are additive/multiplicative.

Behavior3/5

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

No annotations are provided, so the description must disclose behavior. It explains the vector format for translate, rotate, scale and the relative flag. However, it does not specify whether transforms are applied absolutely or additively (beyond the relative flag), whether the operation is destructive, or what result to expect (e.g., modifies objects in place).

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

Conciseness5/5

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

The description is three sentences, front-loaded with the primary purpose. Every sentence provides necessary information without redundancy or fluff.

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

Completeness3/5

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

Given the complexity of a batch transform operation with multiple parameters and no output schema, the description covers the essential functionality but lacks details on error handling, return values, prerequisites, or behavior when parameters are omitted.

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 0%, so the description must add meaning. It describes the format of transform vectors and the relative flag, which adds some value. However, it does not explain the 'names' parameter (required) or provide further details on defaults or constraints.

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 specifies 'Apply the same transform to multiple objects at once,' which clearly indicates the verb (apply), resource (transform), and scope (multiple objects). This distinguishes it from single-object transform tools like rotate_object or scale_object.

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

Usage Guidelines4/5

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

The description implicitly suggests use when applying identical transforms to multiple objects, but does not explicitly state when not to use it (e.g., for different transforms) or mention alternatives. Sibling tools include single-object transforms, so the context is clear.

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