# SCAFFOLDER
|
||
|
||
## ROLE
|
||
Create the empty skeleton of a project and make it buildable.
|
||
|
||
## GOAL
|
||
Deliver a project where:
|
||
- Folder structure and config files are in place
|
||
- CLAUDE.md is fully filled from the global template
|
||
- Dependencies are installed and the project builds
|
||
- Docker config is present if the project type warrants it
|
||
- The project works both natively AND with Docker (if Docker was added)
|
||
- Entry points exist but contain no business logic
|
||
- The implementation pipeline can start immediately
|
||
|
||
**The Scaffolder does NOT implement features.**
|
||
All business logic, feature code, and tests are handled by
|
||
superpowers:writing-plans + subagent-driven-development.
|
||
|
||
---
|
||
|
||
## INPUT REQUIRED
|
||
|
||
1. PROJECT BRIEF (from interviewer)
|
||
2. Approved DESIGN (from brainstorming)
|
||
3. `~/.claude/templates/project-CLAUDE.md`
|
||
4. `~/.claude/CLAUDE.md`
|
||
|
||
If any input is missing → STOP and report.
|
||
|
||
---
|
||
|
||
## PHASE 0 — DOCKER DECISION
|
||
|
||
Before creating any files, decide if Docker is relevant.
|
||
|
||
**Docker IS relevant** if ANY of these apply:
|
||
- Project type is: web app, API, backend service, microservice, SaaS
|
||
- Project has external runtime dependencies: database, Redis, Kafka, RabbitMQ, S3
|
||
- PROJECT BRIEF or DESIGN mentions: deploy, deployment, container, Docker, cloud
|
||
- The project is meant to be run as a persistent server/service
|
||
|
||
**Docker is NOT relevant** if the project is:
|
||
- A library / package (npm, pip, crate, Go module)
|
||
- A CLI tool with no server component
|
||
- A WordPress theme or plugin
|
||
- A device driver or system plugin
|
||
- A mobile app (Flutter, React Native)
|
||
- A C/C++ project without networked services
|
||
|
||
Store this decision as `DOCKER_RELEVANT = true/false`.
|
||
|
||
**If DOCKER_RELEVANT = true**, Docker config is added as a parallel option.
|
||
The project MUST still work natively without Docker.
|
||
Docker is an additional way to run it, not a replacement.
|
||
|
||
---
|
||
|
||
## PHASE 1 — GENERATE PROJECT CLAUDE.md
|
||
|
||
Read `~/.claude/templates/project-CLAUDE.md` in full.
|
||
Read `~/.claude/CLAUDE.md` to understand global rules.
|
||
|
||
Fill in every section from the PROJECT BRIEF and approved DESIGN.
|
||
No placeholders. No template examples left in.
|
||
Mark irrelevant sections as `N/A — <reason>`.
|
||
|
||
Required content:
|
||
- Project overview (2–4 sentences)
|
||
- Stack (language + version, framework, runtime, database)
|
||
- Build commands (exact, native)
|
||
- Test commands (exact)
|
||
- Lint/format commands (exact or N/A)
|
||
- Docker commands (if DOCKER_RELEVANT) — exact
|
||
- Folder structure (actual tree)
|
||
- Architecture (module responsibilities, data flow)
|
||
- Project conventions
|
||
- Exceptions to global rules (or "none")
|
||
- Key dependencies (name — purpose)
|
||
- Workflow expectations
|
||
|
||
Write to `CLAUDE.md` at the project root.
|
||
|
||
---
|
||
|
||
## PHASE 2 — GENERATE SETTINGS
|
||
|
||
### a. `.claude/settings.json`
|
||
Read `~/.claude/templates/settings/settings.json`.
|
||
Adapt `allow` rules to this stack:
|
||
- Keep only blocks relevant to this stack
|
||
- Add stack-specific commands
|
||
- If DOCKER_RELEVANT: add `Bash(docker compose *)`, `Bash(docker build *)`
|
||
- Add project-specific `ask` rules
|
||
|
||
### b. `.claudeignore`
|
||
Read `~/.claude/templates/settings/.claudeignore`.
|
||
Extend with stack-specific exclusions.
|
||
If DOCKER_RELEVANT: no extra exclusions needed (Docker artifacts already in base template).
|
||
|
||
### c. Print:
|
||
```
|
||
⚙️ SETTINGS SETUP
|
||
.claude/settings.json created
|
||
.claudeignore created
|
||
|
||
Manual: copy ~/.claude/templates/settings/settings.local.json
|
||
→ .claude/settings.local.json (gitignore it, never commit)
|
||
```
|
||
|
||
---
|
||
|
||
## PHASE 3 — SCAFFOLD STRUCTURE
|
||
|
||
Create every folder and file from the approved DESIGN.
|
||
|
||
### Universal required files:
|
||
| File | Content |
|
||
|---|---|
|
||
| `CLAUDE.md` | Generated in Phase 1 |
|
||
| `.gitignore` | Stack-appropriate, comprehensive |
|
||
| `.env.example` | All env vars with description, no real secrets |
|
||
| `.claude/settings.json` | Generated in Phase 2 |
|
||
| `.claudeignore` | Generated in Phase 2 |
|
||
|
||
### Entry points and modules:
|
||
- Entry point files exist with minimal structure (imports + empty main/app init)
|
||
- Module/package files exist but are empty or have minimal declarations
|
||
- No business logic anywhere
|
||
|
||
### Stack-specific required files:
|
||
|
||
**Node.js / TypeScript**
|
||
```
|
||
package.json — name, scripts (dev/build/test/lint), dependencies
|
||
tsconfig.json — if TypeScript
|
||
.eslintrc — lint config
|
||
src/index.ts — empty entry point with comment
|
||
```
|
||
|
||
**React (frontend)**
|
||
```
|
||
package.json — scripts: dev, build, preview, test, lint
|
||
vite.config.ts — bundler config
|
||
src/main.tsx — minimal entry point
|
||
src/App.tsx — empty root component
|
||
src/components/ — empty folder
|
||
index.html — entry HTML
|
||
```
|
||
|
||
**Python**
|
||
```
|
||
pyproject.toml or requirements.txt
|
||
src/<package>/__init__.py
|
||
src/<package>/main.py — empty entry point
|
||
```
|
||
|
||
**FastAPI / Flask / Django**
|
||
```
|
||
requirements.txt — pinned dependencies
|
||
src/<pkg>/main.py — app init only (no routes yet)
|
||
src/<pkg>/routes/ — empty folder
|
||
src/<pkg>/models/ — empty folder
|
||
.env.example — DATABASE_URL, SECRET_KEY, etc.
|
||
alembic.ini — if using SQLAlchemy
|
||
```
|
||
|
||
**Rust**
|
||
```
|
||
Cargo.toml
|
||
src/main.rs or src/lib.rs — empty main / empty lib
|
||
```
|
||
|
||
**Go**
|
||
```
|
||
go.mod
|
||
cmd/<app>/main.go — empty main
|
||
internal/ — empty folder
|
||
```
|
||
|
||
**C / C++**
|
||
```
|
||
Makefile — targets: all, clean, fclean, re (-Wall -Wextra -Werror)
|
||
src/ — empty
|
||
include/ — empty
|
||
main.c or main.cpp — empty main
|
||
```
|
||
|
||
**PHP / WordPress Theme**
|
||
```
|
||
style.css — theme header (Name, Description, Version, etc.)
|
||
functions.php — empty theme setup
|
||
index.php — minimal template
|
||
```
|
||
|
||
**Flutter / Dart**
|
||
```
|
||
pubspec.yaml
|
||
lib/main.dart — minimal MaterialApp / CupertinoApp
|
||
lib/app/ — empty folders
|
||
```
|
||
|
||
### Docker config (ONLY if DOCKER_RELEVANT = true):
|
||
|
||
Create these files IN ADDITION to the native stack files above.
|
||
The project must still run without Docker.
|
||
|
||
**`Dockerfile`** — multi-stage build:
|
||
```dockerfile
|
||
# Stage 1: build
|
||
FROM <base-image>:<version> AS builder
|
||
WORKDIR /app
|
||
COPY <manifest-file> .
|
||
RUN <install-deps-command>
|
||
COPY . .
|
||
RUN <build-command>
|
||
|
||
# Stage 2: production
|
||
FROM <minimal-base-image> AS production
|
||
WORKDIR /app
|
||
COPY --from=builder /app/<build-output> .
|
||
EXPOSE <port>
|
||
CMD [<start-command>]
|
||
```
|
||
Adapt image, ports, and commands to the actual stack.
|
||
Use non-root user for security.
|
||
|
||
**`docker-compose.yml`** — all services:
|
||
```yaml
|
||
services:
|
||
app:
|
||
build: .
|
||
ports:
|
||
- "<host-port>:<container-port>"
|
||
env_file: .env
|
||
depends_on: [<db-service>] # only if DB present
|
||
|
||
# Add only services actually needed:
|
||
db: # if project uses a relational DB
|
||
image: postgres:16-alpine # or mysql:8 / mariadb:11 as appropriate
|
||
environment:
|
||
POSTGRES_DB: ${DB_NAME}
|
||
POSTGRES_USER: ${DB_USER}
|
||
POSTGRES_PASSWORD: ${DB_PASSWORD}
|
||
volumes:
|
||
- db_data:/var/lib/postgresql/data
|
||
|
||
redis: # only if project uses Redis
|
||
image: redis:7-alpine
|
||
|
||
volumes:
|
||
db_data:
|
||
```
|
||
|
||
**`.dockerignore`**:
|
||
```
|
||
node_modules/
|
||
.git/
|
||
.env
|
||
dist/
|
||
build/
|
||
target/
|
||
__pycache__/
|
||
*.pyc
|
||
.pytest_cache/
|
||
coverage/
|
||
```
|
||
|
||
After creating Docker files, add to `.env.example`:
|
||
```
|
||
# Docker (optional — only needed when using docker compose)
|
||
COMPOSE_PROJECT_NAME=<project-slug>
|
||
```
|
||
|
||
---
|
||
|
||
## PHASE 4 — INSTALL DEPENDENCIES
|
||
|
||
Install project dependencies so the build works.
|
||
This is mandatory — the build verification in Phase 5 requires installed deps.
|
||
|
||
Run the appropriate install command for the stack:
|
||
|
||
| Stack | Install command |
|
||
|---|---|
|
||
| Node.js / React / TypeScript | `npm install` |
|
||
| Python / FastAPI / Flask | `pip install -r requirements.txt` or `uv pip install -r requirements.txt` |
|
||
| Rust | `cargo fetch` |
|
||
| Go | `go mod download` |
|
||
| Flutter | `flutter pub get` |
|
||
| PHP / Composer | `composer install` |
|
||
| C / C++ | No package manager — verify compiler is available: `gcc --version` or `clang --version` |
|
||
|
||
If the install command fails:
|
||
1. Read the error output
|
||
2. Fix the config file causing the failure (package.json, requirements.txt, etc.)
|
||
3. Retry
|
||
4. If it still fails after one fix attempt → report the error and stop
|
||
|
||
If DOCKER_RELEVANT = true, also verify Docker is available:
|
||
```bash
|
||
docker --version && docker compose version
|
||
```
|
||
If Docker is not installed, print a warning but do not fail — native install continues.
|
||
|
||
---
|
||
|
||
## PHASE 5 — VERIFY SKELETON
|
||
|
||
Run the build command on the empty project.
|
||
The project must compile/start even with no features.
|
||
|
||
```bash
|
||
# Native build
|
||
<build-command from CLAUDE.md>
|
||
```
|
||
|
||
If build fails:
|
||
1. Read the full error
|
||
2. Fix the issue (missing import, wrong path, syntax error in empty file, etc.)
|
||
3. Retry — maximum 2 attempts
|
||
4. If still failing → report what was attempted and stop
|
||
|
||
If DOCKER_RELEVANT = true, also verify Docker build:
|
||
```bash
|
||
docker build -t <project-name>:skeleton-test . --quiet
|
||
```
|
||
Docker build failure is a warning, not a blocker — native must pass.
|
||
|
