Print ready check
Run the machine-checkable ready gate on an STL and report READY/NOT-READY with per-gate evidence (watertight, normals, bed-fit, min-feature). Trigger: "is this printable", "check my STL", "why does my print fail". NOT a slicer and NOT a substitute for material/temperature tuning.From its SKILL.md

2 things to look at
- no licenseNo license file was found in the repository. Code published without one is not open source by default, so using it at work is a question for whoever answers licensing questions where you are.
- 0 stars0 stars. Stars are a popularity signal and not a quality one, but at this level it is likely that nobody has read this closely except its author, and you would be relying on your own review.
What its file declares
Copied from the file, not written here
The file declares its own license as MIT. That is the author’s claim about this one file, and it is not the same thing as the license GitHub reports for the repository, which is listed with the other numbers below.

When to use
Any mesh claiming to be 3D-print ready — generated here or anywhere else.
What it does
- Parse the STL (binary or ASCII, stdlib-only).
- G1 watertight: every directed edge matched by exactly one reverse edge.
- G2 outward normals: signed volume > 0.
- G3 bed-fit against the declared printer envelope.
- G4 min-feature ≥ 2× nozzle diameter.
- Emit a JSON report; exit 0 only if all gates pass.
Example
python3 pipeline/ready_gate.py model.stl --bed 256x256x256 --nozzle 0.4 --min-feature 1.2 --json
Verification (eval-with-teeth)
The gate must catch known-bad meshes — the test suite deletes a triangle (hole), inverts winding (inside-out), and oversizes the model, and asserts each fails its gate:
python3 -m pytest tests/test_ready_gate.py -q
Safety
A READY verdict means geometrically printable, not fit-for-purpose; load-bearing parts need engineering review.
Cross-runtime
Stdlib Python CLI; exit codes gate any CI.
