spring-boot-architecture

spring-boot-architecture is a cursor rule for Cursor from lsampaioweb/ai-instructions. It costs 0 tokens per session (2,184 once invoked), scanned A, original, MIT.

A baseline set of architecture rules for generating and reviewing Spring Boot applications, a Java framework for building web and backend services. It points to more specific rules for areas such as monitoring, API versioning, application startup, and asynchronous events.

In plain words
What is it for?
Planning or reviewing Spring Boot code, including application structure, health and metrics endpoints, API changes, startup configuration, and event handling.
Why use it?
It provides a common checklist for application design and directs work to the relevant component rules.

Token cost

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.

Security

Grade A, and why

spring-boot-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 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.

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.

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-architecture is a cursor rule published in the GitHub repository lsampaioweb/ai-instructions (1 stars, last pushed 13d ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 2,184 tokens. 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 2026-08-31.
