spring-transactions-and-concurrency

spring-transactions-and-concurrency is a skill for Claude Code, Codex from gabrielrovesti/ai-agent-skills. It costs 41 tokens per session (1,208 once invoked), scanned A, original, no licence file.

A guide to transactions, caching, and concurrent database work in Spring and JPA. JPA is a Java standard for working with databases; the guide covers annotations such as @Transactional and @Cacheable, locking, and rollback.

In plain words
What is it for?
Use it to investigate lost updates, duplicate records, LazyInitializationException, locking problems, rollback issues, or ignored transaction and cache annotations.
Why use it?
Database operations can overlap, fail to roll back, create duplicate rows, or access data after a session has closed. It also addresses annotations that appear to have no effect.

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-transactions-and-concurrency 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 2d 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.
