inset_faces

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

No annotations are provided, and the description is a bare name that reveals no behavioral traits. It doesn't explain side effects (e.g., whether it creates new geometry in-place), prerequisites (e.g., active selection), or what kind of result to expect. The description carries zero informational burden.

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?

While the description is technically short, this is under-specification rather than conciseness. The single phrase 'Blender Studio Pro MCP: inset_faces' contributes nothing beyond the tool name, so it doesn't earn its place. It could be removed entirely without losing information.

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 mesh-editing tool with two parameters, no annotations, and no parameter documentation, the description is grossly inadequate. An agent cannot safely or correctly invoke this tool without additional context about preconditions, effect, or expected input values. The presence of an output schema does not compensate for the total lack of guidance.

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?

Schema description coverage is 0%, and the description adds nothing about 'depth' or 'thickness' – their semantics, units, allowed ranges, or how they affect the inset operation. Since the parameters have defaults but no descriptions and no enums, the description was the only way to convey meaning, and it completely fails.

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 a tautology – 'Blender Studio Pro MCP: inset_faces' merely restates the tool name with a prefix. It provides no verb, resource, or scope that would help an agent understand what the tool does, and it fails to distinguish it from dozens of other geometry manipulation siblings like 'bevel', 'subdivide', or 'merge_by_distance'.

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 zero guidance on when to use this tool vs alternatives. No context about whether it operates on faces in edit mode, whether it requires a selection, or what the typical workflow should be. An agent has no way to decide when to call inset_faces over other mesh-editing tools.

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