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.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00046 | $0.00707 |
| Opus 5 | $0.00023 | $0.00353 |
| Sonnet 5 | $0.00009 | $0.00141 |
| Haiku 4.5 | $0.00005 | $0.00071 |
Grade A, and why
microservices-architecture 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 9d 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.

Microservices Architecture
Table of Contents
Overview
Comprehensive guide to designing, implementing, and maintaining microservices architectures. Covers service decomposition, communication patterns, data management, deployment strategies, and observability for distributed systems.
When to Use
- Designing new microservices architectures
- Decomposing monolithic applications
- Implementing service-to-service communication
- Setting up API gateways and service mesh
- Implementing service discovery
- Managing distributed transactions
- Designing inter-service data consistency
- Scaling independent services
Quick Start
Minimal working example:
Bounded Contexts:

Best Practices
✅ DO
- Design services around business capabilities
- Use asynchronous communication where possible
- Implement circuit breakers for resilience
- Use API gateway for cross-cutting concerns
- Implement distributed tracing
- Use service mesh for service-to-service communication
- Design for failure (chaos engineering)
- Implement health checks for all services
- Use correlation IDs for request tracking
- Version your APIs
- Implement proper monitoring and alerting
- Use event-driven architecture for loose coupling
- Implement idempotent operations
- Use database per service pattern

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.

microservices-architecture is a skill published in the GitHub repository aj-geddes/useful-ai-prompts (338 stars, last pushed 6mo ago), licensed MIT. It adds 46 tokens to every session and 707 once invoked, about $0.0002 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 2026-09-03.
