img2threejs — Image to procedural Three.js

Rebuild the object visible in a reference image as a code-only procedural Three.js model, gated by a staged sculpting pipeline and an AI-vision self-correction loop. This is reconstruction-by-code, not photogrammetry, mesh extraction, or downloaded art packs. That promise governs how the model is built — it says nothing about which file formats it can subsequently be exported to; an explicitly-selected emission target (--target <kind>) is a terminal, whole-artifact transform of the already-built model, verified to its own stated limit, never a second way to build one.

Agent-agnostic: works under Claude Code, Codex, or OpenCode. Wherever this doc says "agent vision" or "agent browser tool", use whatever the host provides — native image reading, a browser MCP (playwright/chrome-devtools), the project preview, or a user-supplied screenshot.

This file is the always-loaded router: it holds the order of operations and every hard rule as one line. The full contract behind each rule lives in the grimoire/ or docs/ file that rule names — read the named file at the moment you reach that stage, not before.
