qrcodly CLAUDE.md

qrcodly CLAUDE.md is an instructions file for coding agents from FloB95/qrcodly. It costs 2,265 tokens per session, scanned A, original, MIT.

Project instructions for QRcodly, a full-stack QR-code generator and management platform organized as a pnpm monorepo. A monorepo keeps several related applications and shared packages in one repository.

In plain words
What is it for?
Use them to start local services, run the applications, build the project, and understand where its API, web app, extension, and shared packages live.
Why use it?
They give a coding agent the project layout, development commands, build order, and service requirements. This reduces guesswork when working across the backend, frontend, browser extension, and shared code.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

qrcodly CLAUDE.md scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 4d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Project Overview

QRcodly is a full-stack QR code generator and management platform. It's a pnpm monorepo.

├── backend/           # Fastify REST API (Node.js)
├── frontend/          # Next.js 16 web application (React 19)
└── browser-extension/ # Vite-based browser extension

Commands

Development

# Start local services (MySQL, Redis, MinIO, etc.)
cd apps/backend && pnpm run dev-server   # or: docker-compose up -d

# Run both apps
pnpm run start:dev

# Run individually
pnpm run backend:dev     # Fastify API at :5001 (runs migrations first)
pnpm run frontend:dev    # Next.js at :3000 (uses Turbopack)

Building

pnpm run build                 # Build all apps
pnpm run build:shared-package  # Build shared package only (must run before app builds)
pnpm run backend:build         # Build backend (builds shared first)
pnpm run frontend:build        # Build frontend (builds shared first)

Testing

# Backend tests (Jest)
cd apps/backend
pnpm run test                    # Run all tests (runs migrations first, uses --runInBand)
pnpm run test -- path/to/test    # Run specific test file
pnpm run test:coverage           # Run with coverage

# Pre-PR validation
pnpm run pr:precheck             # lint + typecheck + test + build

Linting & Type Checking

pnpm run lint            # Lint all workspaces
pnpm run format          # Prettier format entire repo

# Per-app
cd apps/backend && pnpm run lint && pnpm run typecheck
cd apps/frontend && pnpm run check  # runs lint + typecheck

Database

cd apps/backend
pnpm run db:migrate              # Apply migrations (runs automatically with dev/test)
pnpm run db:generate-migration   # Generate new migration from schema changes
pnpm run studio                  # Open Drizzle Studio

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
