Getting it into your agent
There is no command for this one: it runs only inside a plugin, and the catalogue could not identify which plugin ships it. The source is linked below.

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 5.1 | $0.22546 | $0.22546 |
| Opus 5 | $0.11273 | $0.11273 |
| Sonnet 5 | $0.04509 | $0.04509 |
| Haiku 4.5 | $0.02255 | $0.02255 |
Grade C, and why
My-Distributed-Bookstore CLAUDE.md scanned grade C with 2 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 5d 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.

rm -rf with a variable or a broad path is one typo away from removing the wrong tree.

Not a fault in itself. Listed so you know the mod talks to something, and to what.

Project Overview
A production-ready distributed bookstore system built with microservices architecture on AWS EKS, following industry best practices and principles from "Distributed Systems" by Tanenbaum & van Steen. This project demonstrates real-world implementation of distributed systems concepts including event-driven architecture, saga patterns, gRPC communication, and comprehensive observability.
Tech Stack
Backend Microservices (Polyglot Architecture):
- Go 1.21+: Primary language for high-performance services
- Fiber (web framework)
- GORM (ORM)
- gRPC with Protocol Buffers
- Node.js/TypeScript: For I/O-bound services
- Express.js
- Payment gateway integrations
- WebSocket support
- Python 3.11+: For ML/AI services
- FastAPI
- scikit-learn (recommendations)
- NLTK (sentiment analysis)
- JWT: Authentication & authorization
- PostgreSQL 15: Primary relational database
- Redis 7: Caching, sessions, rate limiting
- RabbitMQ 3.12: Message broker for async communication
Frontend:
- TypeScript + React 18+
- shadcn/ui component library
- TanStack Query v5 (data fetching)
- Zustand (state management)
- React Router v6
- Tailwind CSS
Infrastructure:
- Docker & Docker Compose (local development)
- Kubernetes 1.28+ (AWS EKS)
- Nginx Ingress Controller
- PostgreSQL (per-service databases)
- Redis (shared cache cluster)
- RabbitMQ (StatefulSet cluster)
- S3 (static assets, book covers)
- CloudFront (CDN)
- Route53 (DNS)
- ACM (SSL certificates)
Observability:
- Jaeger (distributed tracing)
- Prometheus (metrics collection)
- Grafana (visualization dashboards)
- ELK Stack (centralized logging)
- Fluentd (log shipping)
- Elasticsearch (log storage)
- Kibana (log analysis)
Architecture Principles
Microservices Design
- Database per Service: Each microservice owns its data
- API Gateway Pattern: Single entry point for clients
- Service Discovery: Kubernetes DNS
- Event-Driven Architecture: Asynchronous communication via RabbitMQ
- Saga Pattern: Distributed transactions without 2PC
- CQRS: Separate read/write models for complex queries
- Circuit Breaker: Fault tolerance with automatic recovery
- Health Checks: Liveness and readiness probes
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.

My-Distributed-Bookstore CLAUDE.md is an instructions file published in the GitHub repository Youngermaster/My-Distributed-Bookstore (2 stars, last pushed 10mo ago), licensed Apache-2.0. It adds 22,546 tokens to every session, about $0.1127 per session on Opus 5. A static security scan graded it C with 2 findings (recursive force delete, makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
