kernelcad-authoring SKILL.md skillA
kernelcad-authoring from w1ne/kernelcad-web is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add w1ne/kernelcad-web/kernelcad-authoring@git:20261019.055d317Pins git:20261019.055d317 in mdr.lock. Pin the fingerprint instead.

kernelCAD model authoring API — primitives, transforms, booleans, sketches, path-builder, sketch-text, return-single-shape rule, conventions, CLI commands, and verification gates. Load this when writing or modifying .kcad.ts geometry.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# kernelCAD — authoring
Write or edit `.kcad.ts` TypeScript models; run `kernelcad evaluate <file>` or `kernelcad export stl|step|dxf|3mf|glb <file> -o <out>`.
Single-file scripts refuse top-level `import`/`require` with `feature.invalid-args`; define helpers in the same file.
This file is the core: units, the rules that prevent most failures, which API serves which intent, and the finish checklist. The full reference (every signature, CLI flag, material, recipe) lives in `references/*.md` beside this file; over MCP pull it with `lookup_authoring_skill({ section: '<id>' })` or `{ query: '...' }` (index at the end).
## Coordinate System
- **Z-up**, right-handed. Lengths in millimetres, angles in degrees.
- `box(x, y, z)`: corner-anchored at the origin (spans `[0, x] × [0, y] × [0, z]`). `box(x, y, z, true)` centres ALL three axes.
- `cylinder(h, r)`: axis along Z, centred in X/Y, base at `z = 0`, top at `z = h` (no centred flag).
- `sphere(r)`: centred on the origin.
- `path()...close()` builds a Sketch in XY; `.extrude(d)` goes +Z; `.revolve()` turns the (radial X, axial Z) profile about Z.

How to install
mdr add w1ne/kernelcad-web/kernelcad-authoring@sha256:741662c91ac4cd8cThe line at the top of this page pins the label git:20261019.055d317, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
