用 REA + Opus 5.5 + Jev 复刻付费 SaaS 内部工具
思路是用 REA 摸清某个付费功能的行为，Opus 5.5 生成自建工具规格，Jev 挡在昂贵调用前决定哪些需要深挖、哪些复用已有结果，从而砍掉每月 500 美元的订阅。
It is becoming f*cking dangerous: REA + Opus 5.5 + Jev could replace the apps you pay $500 a month for you’re paying for the whole app when your team only uses a few features — build those and give yourself a reason to cancel give Opus one feature to investigate, use REA to understand its behavior, then turn the findings into a spec for your own internal tool put Jev before the expensive calls to decide what needs deeper analysis and what can use saved findings, so Opus gets a clear task instead of another open-ended investigation save the results and failed checks so the next attempt fixes one problem instead of paying to repeat the whole process the engineer who brings a working internal tool to Monday standup, replaces a recurring subscription, and shows how cheaply it runs gives the team something worth paying attention to the Opus 5.5 + Jev article below walks through the routing, saved results, and targeted retries that make this workflow cheaper to run ↓
