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 5.1 | $0.00082 | $0.01794 |
| Opus 5.5 | $0.00033 | $0.00718 |
| Sonnet 5.5 | $0.00016 | $0.00359 |
| Haiku 4.5 | $0.00008 | $0.00179 |
Grade A, and why
spring-boot-production-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 18d 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.

Spring Boot Production Architecture Skill Guide
This skill provides architectural patterns, production configurations, and idiomatic Java 21 code standards for building enterprise-grade, high-throughput microservices using Spring Boot 3.3+.
1. Architectural Layers & Virtual Thread Concurrency
Modern Spring Boot 3 applications leverage Java 21 Virtual Threads (Project Loom) to achieve non-blocking concurrency without reactive boilerplate.

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.

spring-boot-production-architecture is a skill published in the GitHub repository hamzabellouch/agent-skills (8 stars, last pushed today), licensed MIT. It adds 82 tokens to every session and 1,794 once invoked, about $0.0003 per session on Opus 5.5. 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 2026-09-29.
