solidify_mesh

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

Annotations already declare destructiveHint=true, so the safety profile is known. The description adds that this is a Solidify modifier, providing a useful clue about its procedural nature. However, it does not disclose what happens to the original geometry, whether the modifier is applied or left unapplied, or any side effects beyond adding thickness. This is minimal but not misleading.

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 a single, front-loaded sentence with no filler. It is appropriately brief for a simple operation, but given the lack of parameter context, it leans toward under-specification rather than effective conciseness. Still, it earns points for economy of words.

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?

The tool has 3 parameters and an output schema, but the description is minimal. It does not explain the role of offset (a scaling factor) or thickness (the amount of skin added), nor does it distinguish this from similar siblings like add_wall_thickness. Given the ambiguity and missing parameter semantics, the description is incomplete for a destructive modification tool.

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 does not explain any of the parameters (offset, thickness, object_name). It only says 'Add skin thickness' without mapping these terms to specific effects. The schema provides default values but no semantic meaning, so the description fails to compensate for the coverage gap.

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 states a clear verb+resource: 'Add skin thickness (Solidify modifier)'. It identifies the tool's function unambiguously and distinguishes it from generic mesh tools by naming the specific modifier. However, it could be more explicit about what the modifier does (e.g., creating an extruded wall around the mesh).

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?

The description offers no guidance on when to use this tool versus alternatives. Sibling tools like add_wall_thickness or bevel_mesh are not mentioned, and no contexts or exclusions are provided. The user is left to infer usage.

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