What it does
Preview Scad is an agent skill from iancanderson/openscad-agent. Render OpenSCAD (.scad) files to PNG images for visual verification. Use this after creating or modifying .scad files to see the 3D result and self-correct if needed.
Its SKILL.md is about 500 tokens, which your agent loads only when the skill is triggered. The skill folder holds 2 other files, including scripts (for example `scripts/render-scad.sh`).
The repository describes itself as: A Claude Code-powered 3D modeling agent environment for creating 3D printable designs using OpenSCAD.
Example prompts
- “/preview-scad”
Requirements
- A Bash shell
- Pre-approved tools (allowed-tools): Bash(*/render-scad.sh*), Read
Workflow steps
4 steps, taken from the first numbered list in SKILL.md.
- After creating or editing a .scad file, run this skill to render a preview
- Read the generated PNG image to visually inspect the result
- If the result doesn't look right, fix the code and re-render
- Repeat until the design matches the requirements
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(*/render-scad.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
Preview Scad loads about 503 tokens when it runs. Until then it costs about 45 tokens; SKILL.md has 208 words of instructions outside code blocks.
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 208 words (~503 tokens).
