+- Pack: `skill-pack-curated-20260807`
+
+Use CAD-SkillX references only after the core build123d references are loaded.
+For a matching request, read one Planning skill first, then add only the
+Functional and Atomic skills required by the requested geometry. Do not read
+the whole pack by default.
+
+Planning skills:
+

+- `references/cad-skillx/planning/flange.planning.md` — flange, circular flange, pipe flange, coupling flange, flanged sleeve, `法兰`, `法兰盘`.
+- `references/cad-skillx/planning/hexagonal-nut.planning.md` — hex nut, hexagonal nut, threaded nut, internal threaded bore, `六角螺母`, `螺母`.
+- `references/cad-skillx/planning/mounting-bracket.planning.md` — mounting bracket, support bracket, L/U/T bracket, bracket with holes, web/lug/tab/boss, `安装支架`, `支架`.

+
+Functional skills:
+
+- `references/cad-skillx/functional/axisymmetric-revolve-strategy.functional.md` — read for axisymmetric/turned bodies, stepped shafts, bushings, washers, sleeves, flange hubs, grooves, or revolved cuts.
+- `references/cad-skillx/functional/bearing-bore-seat.functional.md` — read with bearing housing/seat requests where a shaft clearance bore, bearing pocket, shoulder, or seat depth is required.
+- `references/cad-skillx/functional/flange-bolt-circle.functional.md` — read with flange requests containing bolt circle, pitch circle, PCD, circular bolt pattern, or evenly spaced flange holes.
+- `references/cad-skillx/functional/mounting-plate-hole-layout.functional.md` — read with mounting/base/adapter plates containing rectangular hole grids, edge margins, slots, threaded holes, counterbores, or countersinks.
+- `references/cad-skillx/functional/slotted-adjustment-feature.functional.md` — read when the model needs slots, slotted holes, elongated holes, guide slots, or adjustment slots.
+- `references/cad-skillx/functional/standard-hole-wizard.functional.md` — read whenever standard clearance holes, threaded/tapped holes, counterbores, countersinks, dowel holes, or screw-seat holes are required.
+- `references/cad-skillx/functional/symmetric-feature-layout.functional.md` — read when holes, bosses, tabs, slots, cutouts, or ribs are mirrored, centered, or symmetric about a centerline/midplane.
+
+Atomic skills:
+
+- `references/cad-skillx/atomic/coaxial-bore-rule.atomic.md` — read when bore, pocket, hub, sleeve, bearing seat, shaft clearance, pilot diameter, or counterbore must share one axis.

+- `references/cad-skillx/atomic/extrude-base-profile.atomic.md` — read when the base body is an extruded rectangle, circle, annulus, hexagon, block, plate blank, bracket base, or simple cylinder.
+- `references/cad-skillx/atomic/fillet-chamfer-last.atomic.md` — read when finishing edges with chamfers, fillets, deburring, lead-ins, or stress-relief rounds.

+
+Recommended CAD-SkillX combinations:
+
+- Bearing housing / `轴承座`: planning bearing housing + functional bearing bore seat + atomic coaxial bore; add standard hole wizard, pattern holes, counterbore/threaded/through-hole, and fillet-chamfer-last only if those features are requested.
+- Flange / `法兰`: planning flange + functional flange bolt circle + atomic coaxial bore + pattern holes from datum; add axisymmetric revolve when the flange has a hub, sleeve, steps, grooves, or turned profile.
+- Mounting plate / `安装板`: planning mounting plate + functional mounting plate hole layout; add standard hole wizard, symmetric feature layout, slots, pattern holes, counterbored/threaded/through holes, and fillet-chamfer-last as needed.
+- Mounting bracket / `安装支架`: planning mounting bracket; add standard hole wizard, symmetric feature layout, slotted adjustment, extrude base profile, pattern holes, and fillet-chamfer-last as needed.
+- Simple shaft / cylindrical rod / `轴`: planning simple shaft or cylindrical rod; add axisymmetric revolve or revolve-profile-around-axis for steps/shoulders/grooves, threaded-hole creation for centered end holes, and fillet-chamfer-last for end edge breaks.
+- Hexagonal nut / `六角螺母`: planning hexagonal nut + atomic threaded-hole creation + fillet-chamfer-last; add revolve-profile-around-axis only when using a revolved blank or revolved thread/counterbore.
