add_cloth

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

With no annotations provided, the description carries the full burden of behavioral disclosure. It provides zero information about what the tool does, any side effects, required context, or return behavior. Nothing is revealed beyond the tool's name.

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?

The description is extremely short, which keeps it concise, but it is under-specified rather than concisely informative. It is a single line that repeats the name, providing no useful content. This is not effective conciseness but rather a placeholder.

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 tool with a single parameter and no annotations or schema descriptions, the description is completely inadequate. An agent cannot determine the tool's purpose, how to use it, or what the object_name parameter refers to. Even with an output schema existing, the description fails to provide essential context.

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 schema defines one required parameter 'object_name' with no type or description, and schema description coverage is 0%. The description adds no meaning to this parameter; it does not indicate that it names the target object or any expected format. The description fails to compensate for the lack of schema details.

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 is 'Blender Studio Pro MCP: add_cloth' which merely repeats the tool name with a prefix. It does not state what the tool does, such as adding a cloth simulation to an object. It is a tautology and does not distinguish from sibling tools like add_soft_body or add_rigid_body.

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?

There is no guidance on when to use this tool versus alternatives. The description gives no context about typical use cases, prerequisites, or conditions for selecting this tool over other physics simulation tools.

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