Whole-pass audit of the scaffold found three gaps and closes them: - Guardrail tests only ever passed. The wrangler.toml mapping and the MCP_ENVIRONMENT isolation checks are now pure functions (test/helpers/) tested against mutated input: preview→production, production→fake, local→production, mislabelled env, shared KV id, extra "staging" env, changed entry point, a file reading the binding, a file branching on the environment name. - src/index.ts's misconfiguration path had no test. Added: 500 with the exact mismatch message, memoized failure across requests, missing bindings reported, sound bindings still serve. - fake-upstream had an [env.preview] block it did not need (one deploy target) which made wrangler warn; now top-level only, script `deploy`. Also verified out-of-band and recorded in CLAUDE.md as rules 4–6 of the working method: `pnpm install --frozen-lockfile`, `wrangler deploy --dry-run` for both Workers (production bundle contains no fake code), the eslint boundary rejects a server→fake import, and both Workers boot under `wrangler dev` and answer over HTTP. pnpm check: typecheck, eslint, prettier, 37 tests passing.

The IDE for artists.
ArtCraft
ArtCraft is the IDE for interactive AI image and video creation. We turn prompting into crafting, so your ideas become a form of tangible expression and computing. This is Adobe Photoshop for everyone, and we're giving away the source code!
Show, Don't Tell: Advanced Crafting Features
Text-to-image is great, but artists need control. It's important to know what your image will look like before you generate it, and it's vitally important to achieve consistency and repeatability.
Note: all of the above videos were generated for free with Grok Video; the cost to build this README was negligible.
Quick and Easy Prompting
We haven't abandoned text-to-asset generation for quick prototyping and ideation. We support every popular workflow in a first class fashion.
