physics_add_soft_body

Add soft body physics to an object to simulate deformable behavior. Control mass, friction, speed, and shape retention strength.

Instructions

Add soft body physics to an object.

Args: object_name: Target object mass: Total mass friction: Surface friction speed: Simulation speed multiplier goal_strength: How strongly mesh holds original shape (0=floppy, 1=rigid)

Behavior2/5

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

No annotations provided, so description must disclose behavioral traits. It only states the action and parameter meanings, without mentioning side effects, prerequisites (e.g., mesh requirements), or behavior beyond the basic operation.

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?

Concise format with a single sentence for purpose followed by a list of argument descriptions. No extraneous text, well-structured.

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?

Given the tool has 5 parameters, no output schema, and many sibling physics tools, the description lacks usage context, behavioral details, and expected output. More information is needed for a complete understanding.

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 description coverage is 0%, so description compensates partially. Each parameter has a one-line explanation (e.g., goal_strength explains scale from floppy to rigid). However, explanations are minimal and lack details on ranges or interactions.

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?

Description clearly states 'Add soft body physics to an object,' using a specific verb and resource. It distinguishes from siblings like physics_add_cloth and physics_add_rigid_body by specifying 'soft body'.

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 on when to use this tool vs alternatives (e.g., cloth or rigid body). The description does not provide context or exclusions, leaving selection to the agent.

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