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.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5 | $0.02265 | $0.02265 |
| Opus 5 | $0.01132 | $0.01132 |
| Sonnet 5 | $0.00453 | $0.00453 |
| Haiku 4.5 | $0.00227 | $0.00227 |
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.

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.

qrcodly CLAUDE.md is an instructions file published in the GitHub repository FloB95/qrcodly (25 stars, last pushed 7d ago), licensed MIT. It adds 2,265 tokens to every session, about $0.0113 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
