What is arch-patterns?

A set of production-tested architecture rules for Java Spring back ends and Vue/Nuxt front ends. It defines boundaries between application layers, domain logic, events, exceptions, and UI code.

It helps design Spring services and domains, keep data access behind the right layers, publish domain events, structure custom exceptions, and apply Vue/Nuxt MVVM component and data-fetching rules.

It gives feature work a consistent structure, reducing misplaced business logic, tangled dependencies, and unclear error or event handling.

Security

Grade A, and why

arch-patterns 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 yesterday.

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.

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.
