OpenSCAD Design MCP

Finalize Model

finalize_model

Validate and render a 3D model revision, inspect geometry for watertightness and dimensions, then export to a chosen format; finalize only after all checks pass.

Instructions

Validate, render, export and inspect one revision; finalize only if all gates pass.

TDQS

B3/5.0
Behavior2/5

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

No annotations are provided, so the description carries the full burden. It discloses that finalization is conditional and that the tool performs multiple operations, but it does not state whether finalization is irreversible, locks the revision, requires special permissions, or what happens when any gate fails.

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?

One tightly packed sentence with a front-loaded verb list and a compact conditional clause. Every word contributes either to the composite scope or the gating condition, with no filler or repetition.

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?

For a 7-parameter composite tool with no annotations, the description is too thin. It omits gate definitions, finalization semantics, parameter effects, and failure behavior. An output schema exists, which helps with return values, but it does not compensate for the missing behavioral and parameter context.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters2/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

The input schema has 0% description coverage and the tool description names no parameters. The verbs hint at possible mappings (render to render_views, export to output_format, validate to require_watertight/expected_dimensions), but the description gives no concrete meaning, constraints, or defaults for any of the 7 parameters.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose4/5

Does the description clearly state what the tool does and how it differs from similar tools?

Description uses specific action verbs ('Validate, render, export and inspect') and a conditional 'finalize only if all gates pass,' making the composite purpose reasonably clear. It also distinguishes itself from siblings like render_preview or export_model by bundling multiple gates into one finalization action, though it never defines what 'finalize' means in state terms.

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

Usage Guidelines3/5

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

The phrase 'finalize only if all gates pass' implies this is the final step after validation, rendering, export, and inspection succeed. However, it never explicitly names alternatives or says when not to use this tool instead of calling validate_scad, render_preview, or export_model individually, so usage guidance is only implied.

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