New Project

New Project

Take a raw idea to a running, git-tracked, Claude-ready project skeleton.

Templates are bundled with this skill in templates/ (synced copies — the source of truth is the toolkit repo at X:\Projects\ClaudeCode\templates\; edit there, then re-run sync.ps1).

Copy this checklist and check off items as you complete them:

New Project Progress:
- [ ] Step 1: Gather requirements
- [ ] Step 2: Design gate
- [ ] Step 3: Scaffold by type
- [ ] Step 4: CLAUDE.md + git init
- [ ] Step 5: Verify it runs (mandatory)
- [ ] Step 6: Hand off

Step 1 — Gather

Use what the user already provided (including arguments to this skill); ask only for what's missing.

• Name (kebab-case) and one-line purpose.
• Type: webapp (default), api, or other.
• Location: default X:\Projects\.
• Paid product? If yes, note it — Step 6 points at /monetize.

Step 2 — Design gate

If the product hasn't been brainstormed yet in this conversation, invoke superpowers:brainstorming for the product itself BEFORE scaffolding. Never scaffold an undesigned product. If a design/spec already exists, proceed.

Step 3 — Scaffold by type

If a scaffold command fails, stop and fix it before continuing: read the exact error; for generator flag errors run the generator's --help and adapt — flags drift between versions and the intent below matters more than the exact flags. Never leave a half-scaffolded folder silently: finish it, or delete it and report why.

webapp (Next.js + TypeScript + Tailwind + Supabase):

npx create-next-app@latest  --typescript --tailwind --eslint --app --src-dir --import-alias "@/*" --use-npm --yes
cd 
npm install @supabase/supabase-js @supabase/ssr

Then create .env.example (NEXTPUBLICSUPABASEURL, NEXTPUBLICSUPABASEANON_KEY, commented), src/lib/supabase/ client helpers per current @supabase/ssr docs (fetch them via the context7 MCP tools — the cookie/session patterns change), and a supabase/migrations/ folder. Only create the actual Supabase project when the design needs a database — ask before creating cloud resources.

api (Python + FastAPI):

mkdir ; cd 
python -m venv .venv; .\.venv\Scripts\Activate.ps1
pip install fastapi "uvicorn[standard]" pytest httpx; pip freeze > requirements.txt

Structure: app/main.py (FastAPI instance + health route), app/routers/, app/models.py, tests/test_health.py, .env.example (commented var names, no values). Add app/db.py and a migrations setup only when the design includes a database.

other (CLI, extension, desktop, mobile): consult templates/project-structures.md for the layout, scaffold minimally with the ecosystem's official generator.

Step 4 — Claude-ready

1. Copy the matching template from this skill's templates/ — CLAUDE.webapp.md, CLAUDE.api.md, or CLAUDE.generic.md — to the project root as CLAUDE.md and fill every {{placeholder}}.
2. Check your work: search the new CLAUDE.md for {{ — it must return zero matches.
3. git init; ensure .gitignore covers .env* (except .env.example), node_modules/.venv, build output.
4. Do NOT commit — per global rules the user commits explicitly.

Step 5 — Verify (mandatory)

Run the real check and paste its real output. webapp: npm run build. api: pytest. other: the ecosystem's build/test command.

• Passes → continue to Step 6.
• Fails → fix and re-run until it passes. If you cannot make it pass, report the exact failing output and what you tried — never hand off a skeleton claimed as working without passing output.

Step 6 — Hand off

Report: location, what was scaffolded, verification output. Suggest next actions: run /product-spec for anything non-trivial, write the first vertical slice (superpowers:writing-plans), and if it's a paid product, run /monetize BEFORE building features — pricing shapes scope.
