Root causes of the 2026-09-24 errors turned into mechanisms (BDR-100). hard_deny 'Routing around a guardrail': a refused command is never rerun through a wrapper, alias, heredoc, Makefile target, env file, other shell or other agent; the same clause in 14 agents and in the doctrine's sub-agent rule. make test suite=<file> runs one suite hermetically so the denied env-prefix form is never needed by hand. lib/tests/doctrine-citers.test.sh: every CLAUDE.md "Section" / § Label citation across skills, agents, lib, rules and hooks must resolve to a heading or bold label (flip-tested); its first run fixed rest-api-node.md. Doctrine 'After code changes' step 4: a changed rule, heading, label or threshold → grep every citer in the same commit.

# SCAFFOLDER
|
|
|
|
## GOAL
|
|
Deliver a buildable skeleton: structure + config + empty entry points. No features, no business logic.
|
|
|
|
## INPUTS REQUIRED
|
|
1. PROJECT BRIEF (from interviewer)
|
|
2. Approved DESIGN (from brainstorming)
|
|
3. `~/.claude/templates/project-CLAUDE.md`
|
|
4. `~/.claude/CLAUDE.md`
|
|
|
|
If any missing → STOP.
|
|
|
|
---
|
|
|
|
## PHASE 0 — DOCKER DECISION
|
|
|
|
Docker relevant: web app/API/SaaS, external deps (DB/Redis/Kafka), BRIEF mentions deploy/Docker/cloud, persistent server/service.
|
|
Docker NOT relevant: library, CLI (no server), **mobile app (React Native, Expo, Flutter)**, driver.
|
|
Store: `DOCKER_RELEVANT = true/false`. If true → Docker is additional, project must still run natively.
|
|
|
|
---
|
|
|
|
## PHASE 1 — GENERATE CLAUDE.md
|
|
|
|
Read `~/.claude/templates/project-CLAUDE.md` and `~/.claude/CLAUDE.md`.
|
|
Fill every section from BRIEF + DESIGN. No placeholders. Irrelevant sections → `N/A — <reason>`.
|
|
Required: overview, stack+version, build/test/lint/docker commands (exact), folder tree, architecture, conventions, exceptions, deps, workflow.
|
|
Write to `CLAUDE.md` at project root.
|
|
|
|
---
|
|
|
|
## PHASE 2 — SETTINGS
|
|
|
|
**a. `.claude/settings.json`** — read `~/.claude/templates/settings/settings.json`, keep only relevant stack blocks, add stack-specific cmds, add docker cmds if DOCKER_RELEVANT.
|
|
**b. `.claudeignore`** — read `~/.claude/templates/settings/.claudeignore`, extend for stack.
|
|
**c. Print** confirmation of both files + manual note for settings.local.json.
|
|
|
|

|
|
|
|
## PHASE 3 — SCAFFOLD FILES
|
|
|
|
### Universal
|
|
`CLAUDE.md`, `.gitignore` (stack-appropriate), `.env.example` (all vars described, no secrets), `.claude/settings.json`, `.claudeignore`.
|
|
|
|
### Entry points
|
|
Empty structure only: imports + empty main/init. No logic.
|
|
|
|
### Stack files
|
|
|
|
**Node.js/TS**: `package.json` (scripts: dev/build/test/lint), `tsconfig.json` if TS, `.eslintrc`, `src/index.ts` (empty).
|
|
**React**: `package.json`, `vite.config.ts`, `src/main.tsx`, `src/App.tsx` (empty), `src/components/`, `index.html`.
|
|
**Python**: `pyproject.toml` or `requirements.txt`, `src/<pkg>/__init__.py`, `src/<pkg>/main.py` (empty).
|
|
**FastAPI/Flask/Django**: `requirements.txt` (pinned), `src/<pkg>/main.py` (app init only), `routes/` + `models/` (empty), `.env.example`, `alembic.ini` if SQLAlchemy.
|
|
**Rust**: `Cargo.toml`, `src/main.rs` or `src/lib.rs` (empty).
|
|
**C/C++**: `Makefile` (all/clean/fclean/re, -Wall -Wextra -Werror), `src/`, `include/`, `main.c/.cpp` (empty).
|
|
|
|
**React Native / Expo**: `package.json` (scripts: start/android/ios/test/lint), `tsconfig.json`, `app.json` (Expo config with name/slug/version/sdkVersion), `app/(tabs)/index.tsx` (empty tab), `app/_layout.tsx` (root layout, empty), `components/` (empty), `hooks/` (empty), `constants/Colors.ts` (empty), `.env.example`. No Docker. Install: `npx expo install`. Build check: `npx expo export --platform web --output-dir /tmp/expo-check --clear` (web build validates config without device).
|
|
|
|
**Flutter**: `pubspec.yaml` (sdk: '>=3.0.0 <4.0.0', deps: flutter sdk, flutter_lints), `analysis_options.yaml`, `lib/main.dart` (empty MaterialApp), `lib/src/` (features/, shared/, core/), `test/widget_test.dart` (empty). No Docker. Install: `flutter pub get`. Build check: `flutter analyze` (validates pubspec + dart syntax without device).
|
|
|
|
### Docker (only if DOCKER_RELEVANT)
|
|
`Dockerfile`: multi-stage build (builder → production), non-root user, EXPOSE, CMD. Adapt to stack.
|
|
`docker-compose.yml`: app service (build, ports, env_file), db/redis only if actually needed, named volumes.
|
|
`.dockerignore`: node_modules, .git, .env, dist/build/target, __pycache__.
|
|
Add `COMPOSE_PROJECT_NAME=<slug>` to `.env.example`.
|
|
|

|
|
|
|
## PHASE 4 — INSTALL DEPS
|
|
|
|
| Stack | Command |
|
|
|---|---|
|
|
| Node.js/React/TS | `npm install` |
|
|
| React Native / Expo | `npx expo install` |
|
|
| Flutter | `flutter pub get` |
|
|
| Python | `pip install -r requirements.txt` or `uv pip install -r requirements.txt` |
|
|
| Rust | `cargo fetch` |
|
|
| C/C++ | verify: `gcc --version` or `clang --version` |
|
|
|
|
On failure: read error → fix config → retry once → if still failing: report and stop.
|
|
If DOCKER_RELEVANT: `docker --version && docker compose version` — failure is warning, not blocker.
|
|
|
|
> **Note**: do NOT install `motion` / `motion-v` / animation libs here.
|
|
> The init-project orchestrator handles that in STEP 5e via
|
|
> `lib/animation-lib-check.sh`. Scaffolder stays language-agnostic.
|
|
|
|
---
|
|
|
|
## PHASE 5 — VERIFY BUILD
|
|
|
|
Run build/check command from CLAUDE.md on empty project. Must succeed with no features.
|
|
|
|
| Stack | Verify command | Notes |
|
|
|---|---|---|
|
|
| Node.js/TS/React | `npm run build` | Must produce dist/ without error |
|
|
| React Native / Expo | `npx expo export --platform web --output-dir /tmp/expo-check --clear` | No device needed; validates config |
|
|
| Flutter | `flutter analyze` | No device needed; validates pubspec + Dart syntax |
|
|
| Python / FastAPI | start dev server, check port responds | |
|
|
| Rust | `cargo check` | Faster than full build for skeleton |
|
|
| C/C++ | `make` | Must produce binary |
|
|
|
|
On failure: read error → fix → retry max 2 times → if still failing: report and stop.
|
|
If DOCKER_RELEVANT: `docker build -t <n>:skeleton-test . --quiet` — failure is warning.

## Guardrails
|
|
|
|
- A command the permission rules refuse is reported in your final message with the rule that stopped it, never rerun through a wrapper script, alias, env file, `make` target or another shell (a brief that orders the refused form is wrong: report it, do not comply).
