+description: Preview-first reconstruction of reference-driven hard-surface props, machinery, signage, modular architecture, and hero assemblies as direct Three.js source. Use when building, revising, visually matching, previewing, or preparing a procedural hard-surface model for a Vibe3D registry. Do not use for generic Three.js application code, bitmap editing, characters, organic assets, foliage, terrain, or particle effects.

+
+# Vibe Model
+
+Build direct Three.js models with one short visual loop:
+
+```text
+model source -> deterministic preview -> independent visual critique
+      ^                                      |
+      `----------- highest-impact fix -------'
+```
+
+Before authoring, read both references completely:
+
+- [fast-loop.md](references/fast-loop.md) for capture and critique;
+- [modeling-rules.md](references/modeling-rules.md) for hard-surface geometry
+  rules that prevent generated-looking results and wasted iterations.
+
+## Author
+
+Work directly in the registry model source. In this repository the canonical
+sources live at `assets/prototypes/<model-id>/model.ts` and are compiled into
+the Sci-Fi Kit registry. In another registry, follow its configured source
+directory.
+
+Export `createModel`. It may return a Three.js `Group` or a controller with a
+stable `root`, optional `update`, semantic parts and actions, and idempotent
+`dispose`. Keep preview-only scene setup in `createPreview` rather than inside
+the installed model root.
+
+Use shared primitives and material sources when they preserve the intended
+shape. Keep the model small enough to understand and change in one focused
+edit. Preserve physical bevel widths, clearances, sockets, pivots, semantic
+part anchors, and declared configuration behavior.
+
+## Preview
+
+Capture as soon as the primary silhouette and major secondary masses exist:
+
+```sh
+bun run vibe:model preview \
+  --module assets/prototypes/<model-id>/model.ts \
+  --export createModel \
+  --asset <model-id> \
+  --reference <reference-image>
+```
+
+The local compatibility command `bun run asset:forge preview` may be used
+during migration. Prefer `vibe:model` in new documentation and automation.
+
+Keep the camera deterministic. Change yaw, pitch, width, height, or the preview
+factory only when the reference requires it.
+
+## Critique
+
+Give a fresh critic only the brief, reference, and current beauty image. Ask
+for a resemblance score, what reads correctly, and no more than three
+prioritized fixes.
+
+Score silhouette and proportions first, then major masses and negative space,
+distinctive landmarks, material/value/color read, and detail plausibility.
+Apply the highest-impact correction and capture again.
+
+Stop at a score of 85 or higher, after two plateauing scores, or after ten
+iterations. Treat a plateau as evidence to change the representation or obtain
+better reference evidence.
+
+## Deliver
+
+Keep the accepted TypeScript source and final deterministic preview. Preserve
+runtime anatomy and ownership contracts. Mark preview-only nodes with
+`userData.excludeFromExport = true`.
+
+When a GLB is requested, export the accepted model through the shared portable
+GLB path so procedural wear is baked into standard PBR data. Report the model
+source, final preview, iteration count, accepted score, and unresolved visual
+approximations. Do not commit generated previews or GLBs unless requested.
