At a glance

Export OpenSCAD (.scad) files to STL format with geometry validation.

  • Works in 2 steps: The design has been iterated and looks… → You're ready to export for 3D printing
  • SKILL.md covers When to Use, Usage, Geometry Validation and Example, plus 3 more sections
  • Runs Shell scripts from its folder

What it does

Export Stl is an agent skill from iancanderson/openscad-agent. Export OpenSCAD (.scad) files to STL format with geometry validation. Checks for non-manifold geometry, self-intersections, and other printability issues.

Its SKILL.md is about 560 tokens, which your agent loads only when the skill is triggered. The skill folder holds 2 other files, including scripts (for example `scripts/export-stl.sh`).

The repository describes itself as: A Claude Code-powered 3D modeling agent environment for creating 3D printable designs using OpenSCAD.

Example prompts

  • “/export-stl”

Requirements

  • A Bash shell
  • Pre-approved tools (allowed-tools): Bash(*/export-stl.sh*), Read

Workflow steps

2 steps, taken from the first numbered list in SKILL.md.

  1. The design has been iterated and looks correct in PNG previews
  2. You're ready to export for 3D printing

What it can do on your machine

Read from SKILL.md and the folder at commit d3f3ebf. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves these tools, so the agent can use them without asking each time:

    • Bash(*/export-stl.sh*)
    • Read

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    Ships 1 file in scripts/ (Shell), which the agent can run.

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Export Stl loads about 563 tokens when it runs. Until then it costs about 41 tokens; SKILL.md has 202 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~41
When it runs · the whole SKILL.md, loaded when a task matches
~563

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); the scripts in this folder are not scanned.

SKILL.md

Without a licence we can't republish the file, so here is its outline and opening line. It has 202 words (~563 tokens).

“Convert OpenSCAD files to STL format for 3D printing with automatic geometry validation.”
