crazy-ecommerce-builder

Build or transform ecommerce websites from loose company, product, or brand briefs into unconventional, brand-specific shopping experiences with original ImageGen product imagery. Use when a user asks for a crazy, wild, experimental, unconventional, anti-template, art-directed, or highly memorable online store; wants Codex to invent an ecommerce visual direction from business details; or wants a working storefront that combines creative concepting, generated product photography, responsive implementation, cart interactions, validation, and optional publishing.

ss-build

Build a screen the way the StyleSeed reference demo was built — one command that ENFORCES the full loop (lock the look → build → score → fix to ≥80 → only then show). Use this instead of building UI free-hand; it closes the gap between "knows the rules" and "actually followed them."

Author a Scarf mini-app — a small sandboxed web surface (HTML/CSS/JS) that renders inside a project's cockpit and talks to the bound Hermes session + project data through the versioned window.scarf bridge.

superdesk-dev

Run a local Superdesk development environment. Works only inside the `superdesk/` host repo, with sibling repos (superdesk-client-core, superdesk-planning, optionally superdesk-analytics / superdesk-publisher) cloned into the same parent directory. Wraps the dev scripts under `scripts/dev/` (setup, up, down, extension enable/disable) so non-experts don't have to remember Docker / npm / grunt commands. Invoke when the user wants to do any of: — "set up the local env", "first-time setup", "I just cloned the repo, get me running" — "start the app", "run superdesk locally", "spin up the dev environment" — "stop the app", "shut down the local environment" — "enable the X extension", "add the helloWorld extension", "turn on usageMetrics" — "disable the X extension", "remove the markForUser extension" — "list extensions", "which extensions are available", "what's enabled" Do not invoke for: the fully-containerised workflow (just `docker compose up` against the existing `docker-compose.yml` — no skill needed), running the e2e test suite (that lives in superdesk-client-core), Python/server code changes, production deploys, or work in any repo other than `superdesk/`.
