Return the kernelcad-authoring SKILL.md body — conventions for writing .kcad.ts scripts (imports, parameters, evaluation contract, common pitfalls). U

Run a kernelCAD .kcad.ts script and report pass/fail + feature count + diagnostics. Pass either { file: "<path>" } or { code: "<inline source>" }.

List the features captured by a kernelCAD script — kind, id, params, inputs, transforms count, suppression. Pass either { file } or { code }.

List assembly intent captured by a kernelCAD script: assemblies, parts, named connectors, fixed connections, joints, and aggregate assembly models. Pa

Evaluate a kernelCAD script and return an agent-facing physical assembly inventory: named parts, bboxes, connectors, mates, disconnected solids, mecha

Run + recompute a script, return volume/surfaceArea/bbox for one feature (default: last). Pass { file?, code?, feature_id? }.

List the canonical face names available on a feature (top/bottom/left/right/front/back for box; top/bottom for cylinder; none for sphere or non-primit

Return the boundary edges of a named canonical face on an un-transformed primitive — index, centroid, length, isClosed. Pass { file?, code?, feature_i

Walk the upstream chain of a failing feature. Returns the diagnostics of the requested feature plus the diagnostics of every upstream feature in topol

Edit a param() default value in a kernelCAD script. Returns the modified code as text plus diagnostics from re-evaluating the result. Caller persists

Insert a new feature line into a kernelCAD script before the last top-level return statement. Returns the modified code as text plus diagnostics from
