What it does
Text To Cad is an agent skill from rongxinzy/RongxinAI. Route CAD, robot-description, fabrication, slicing, printer handoff, and local model review tasks through the bundled text-to-cad 0.4.28 runtime. Use for STEP/STP, STL, 3MF, GLB, DXF, URDF, SRDF, SDF, DfAM, G-code, Bambu Labs, off-the-shelf STEP parts, or implicit CAD requests.
Its SKILL.md is about 1.2k tokens, which your agent loads only when the skill is triggered. The skill folder holds 8 other files, including scripts (for example `scripts/bootstrap.py`, `scripts/run.py` and `scripts/runtime.py`).
It sits in Game Development. It works with Python. The repository describes itself as: An all-in-one local AI Agent workspace with a fully self-developed stack. The licence is MIT.
When your agent uses it
- Off-the-shelf STEP parts
- Implicit CAD requests
Example prompts
- “/text-to-cad”
Requirements
- Python 3
What it can do on your machine
Read from SKILL.md and the folder at commit 9c64865. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
Ships 3 files in scripts/ (Python), which the agent can run.
Shell commands in SKILL.md call:
python
From the folder's file list and the shell code blocks in SKILL.md.
Network
Links to these hosts (documentation or services it may open):
github.com
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
Text To Cad loads about 1.2k tokens when it runs. Until then it costs about 73 tokens; SKILL.md has 502 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.

- text-to-cad
- description
- Route CAD, robot-description, fabrication, slicing, printer handoff, and local model review tasks through the bundled text-to-cad 0.4.28 runtime. Use for STEP/STP, STL, 3MF, GLB, DXF, URDF, SRDF, SDF, DfAM, G-code, Bambu Labs, off-the-shelf STEP parts, or implicit CAD requests.
text-to-cad runtime router
This Skill packages the MIT-licensed earthtojake/text-to-cad workflows as one pinned, offline runtime. The upstream files are stored in a checksum-verified archive so the application does not carry several expanded copies of the same CAD runtime.
Required startup
Before reading an upstream workflow, run:
run_skill_script(
skillId="text-to-cad",
script="scripts/bootstrap.py",
args=["--json"]
)The result contains the immutable runtime root and a map of workflow names to absolute directories. Never guess the cache path and never edit files in it.
Workflow routing
Select exactly one primary workflow, then read its SKILL.md completely from
the returned directory. Load another workflow only when the first one explicitly
hands off to it.
| Request | Primary workflow |
|---|---|
| Parametric part, assembly, STEP/STP, measurement, STL/3MF/GLB export | cad |
| Local visual review of CAD, DXF, implicit, or robot files | cad-viewer |
| Purchasable screws, bearings, motors, boards, connectors, STEP parts | step-parts |
| 2D profiles, templates, gaskets, cut layouts, DXF | dxf |
| Robot links, joints, limits, inertials, meshes | urdf |
| MoveIt groups, end effectors, poses, collision rules | srdf |
| Simulation models, worlds, physics, sensors, lights | sdf |
| SendCutSend upload readiness | sendcutsend |
| Mesh wall thickness, overhang, support, orientation, printability | dfam-check |
| Validated mesh to printer-profiled G-code | gcode |
| Explicitly authorized Bambu upload or print start | bambu-labs |
| Browser-native GLSL signed-distance-field modeling | implicit-cad |
Running upstream Python entries
The application only executes scripts located inside the selected Skill. Use the checked proxy instead of calling extracted Python files directly:
run_skill_script(
skillId="text-to-cad",
script="scripts/run.py",
args=["cad", "scripts/gen", "models/widget.step.py", "--write"]
)The first argument is the workflow name, the second is a Python file or Python package entry relative to that workflow, and the remaining arguments are passed unchanged. The proxy rejects path traversal and non-Python entries.
Common translations:
| Upstream instruction | Proxy arguments |
|---|---|
python scripts/gen ... in CAD | cad, scripts/gen, then original arguments |
python scripts/inspect ... | cad, scripts/inspect, then original arguments |
python scripts/snapshot ... | owning workflow, scripts/snapshot, then original arguments |
python scripts/dfam_tool.py ... | dfam-check, scripts/dfam_tool.py, then original arguments |
python scripts/gcode_tool.py ... | gcode, scripts/gcode_tool.py, then original arguments |
| CAD Viewer | start_cad_viewer (the application-managed viewer tool) |
Run commands from the user's workspace so relative model and output paths stay there. The proxy preserves the current working directory.
For local visual review, call start_cad_viewer instead of starting the
viewer server through run_skill_script. The application owns its process
lifetime, waits for readiness, reuses an existing viewer, and stops it with
the managed process tree when the runtime shuts down.
Show full SKILL.md (135 more words)Show less
Non-Python tools
Some workflows call an installed slicer, MoveIt, or another external program.
Follow the selected upstream SKILL.md exactly and use ordinary tool approval
for those external commands. Do not substitute a different backend silently.
Safety and integrity
- The archive SHA-256 is verified before every first extraction.
- Extraction rejects absolute paths, parent traversal, links, devices, and FIFOs.
- Cache contents are immutable runtime files; edit only user workspace sources.
- Never upload a file, connect to a printer, or start a print without explicit user authorization.
- Report missing dependencies, unsupported platforms, viewer startup failures, and unavailable external tools instead of claiming success.
- Preserve the selected upstream workflow's validation and handoff requirements.
Provenance
- Upstream version:
0.4.28 - Upstream commit:
0e94cd1d2b5fa2013d89aa9504ecadcf16ce39f6 - License: MIT
The expert package root contains the full provenance record. Each extracted workflow retains its upstream license file.
