kernelcad-srdf SKILL.md skillA
kernelcad-srdf from w1ne/kernelcad-web is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.

Add planning-group, end-effector, virtual-joint, and allowed-collision metadata on top of an assembly. Use after kernelcad-urdf when the downstream consumer needs motion-planner semantics layered on the URDF.
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 — SRDF export
SRDF layers planning-group and motion-planner semantics on top of a URDF: which joints form an arm, which links form a gripper, which link pairs are safe to ignore for collision-checking, and named pose snapshots. kernelCAD's `export({ target: 'model', format: 'srdf' })` writes the `.srdf` file; the allowed-collision matrix is auto-derived from the existing mate graph.
## When to use
- The assembly has at least one planning group declared via `arm.planningGroup(...)`.
- The downstream consumer needs motion-planner semantics (planning groups, end-effectors, named pose states, allowed-collision matrix).
Always pair with `kernelcad-urdf`: SRDF is a layer over URDF, not a standalone description.
## Capture-time API
Five capture-time methods on the `arm.*` namespace. Each is declarative — the methods record intent; `export` materialises the SRDF later.
```typescript
arm.planningGroup('main', { chain: { baseLink: 'base', tipLink: 'tool_tip' } });
arm.planningGroup('gripper', { joints: ['gripper-open'] });
arm.endEffector('tool', { parentLink: 'tool_tip', group: 'gripper', parentGroup: 'main' });

How to install
mdr add w1ne/kernelcad-web/kernelcad-srdf@sha256:8b33d661708393f0The line at the top of this page pins the label git:20260613.17ce236, 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.
