逆向工程变便宜了：编码智能体正在改变家庭设备自动化的成本逻辑

我不断听到人们分享使用编程代理来逆向工程和自动化家用设备的趣闻。

我认为这是一个很有趣的例子，展示了编写代码成本下降的影响。

在有代理之前，逆向工程家用设备完全是可能的。问题在于投资回报率——这一切努力真的值得吗？更重要的是，任何有经验的程序员都知道，像这样的无文档、不稳定的 API 很可能在未来发生变化或失效。如果你注定要在未来陷入令人沮丧的维护循环，这最初的工作是否值得呢？

编程代理完全改变了这个局面。让简单自动化运行的努力成本下降了，尝试失败的成本也降低了。由于代码成本很低，将来维护它——或者丢弃重来——的心理负担也小得多。

I keep hearing anecdotes from people who used coding agents to reverse-engineer and automate devices in their homes.

I think this is an interesting illustration of the impact of the reduced cost of writing code.

Prior to agents, it was entirely possible to reverse-engineer home devices. The problem was the ROI - was it really worth all of that effort? More importantly, any experienced programmer knows that undocumented, unstable APIs like that may well change or break in the future. Is that initial work worth the effort if you're committing yourself to a frustrating cycle of maintenance in the future?

Coding agents change that equation entirely. The effort to get a simple automation working has dropped, as has the cost of trying and failing to get it to work. Since the code is so cheap, the idea of having to maintain it in the future - or throw it away and start again - carries way less psychological baggage.
