pstack v0.15.27 ships with a new skill /create-formal-verification-skill! it's still in beta, and similar to /create-verification-skill, this is a meta-skill that creates a new skill and formal verification suite based on the characteristics you want to verify. for example, you may want to model state machines and systems with concurrency using TLA+, or use kani in rust to check for undefined behavior. if you're new to formal verification, think of it as mathematically proving properties and invariants (something that must always be true) or "laws" of your system. usually, this means modeling your programs in a separate language like with TLA+ and then running the solver on that spec. newer approaches like with kani and @bendlang take a different approach where there is no separate language: you write kani in rust, and bend in bend (it's also a programming language, and the proofs are written as laws and expressed in its type system). historically formal verification never reached mainstream status because of the difficulty in modeling and writing proofs. it's quite difficult to model your business requirements and keep them in sync! but i expect that we will see more innovation in formal verification in the future as being able to formally verifiy that the code does what you intended gives your agents superpowers in writing correct software. in the meantime though, i've been experimenting with modeling our code with TLA+ and have already found several bugs with the skill created by /create-formal-verification-skill. try it out and let me know how it goes!

Grok Bot 现在是越来越火了, 特别是 SpaceXsi 统一大订阅之后, 更多人开始使用 Grok Bot , 这里整理一些阅读量比较高的 Grok Bot 主题文章, 9个分类, 24篇文章, 绝对够全方面了解 Grok Bot 了

昨天在去云南的路上，听说昆明附近发生了 4.3 级地震。我想先核对是不是真的，直接用 Grok Bot 问了一下，随后将其开放成一个「地震简报 Earthquake Brief」bot。 你问刚是不是地震了，它会用中国地震台网，全球 USGS。核对信息再说时间、地点、震级、深度。没事就安静，不预测余震，也不替你刷小震。 默认中国国内 4.0 以上、全球 5.0 以上就会主动报告。默认会有间隔的检测，你想问也随时能问。 附图是刚刚今天给我简报了两个地震，需要直接装这个 template。

Cursor 还没切到 X 统一订阅之前，第三方模型的 token 特别经用，我一度以为有什么黑魔法。 用了一阵子，体感很明显：同样干一天活，额度掉得比我预想的慢不少。 我琢磨了几天，答案其实很朴素。 原因在 poteto-mode。 它干活时会拆出很多 subagent 去跑子任务。subagent 用哪个模型，跟你在这次 chat 里选的模型无关，走的是默认配置。 所以你在主对话里选了贵的模型，真正干大量杂活的 subagent 却在用默认模型，额度自然就省下来了。 小技巧：想省额度，主对话用好模型把关，杂活放心交给 subagent。

Grok Bot 的第一场长沙线下活动开始报名了。 时间是 11 月 22 日（周日）下午 2 点到 5 点半，地点在长沙，具体地址会在报名通过后发给大家。 这次主要聊 Grok Bot 的真实使用场景和踩过的坑。如果你已经用它干过活，非常欢迎上来分享。现场还有开放麦，想讲的朋友请在报名时把信息填好。中间有茶歇，也留了自由交流的时间。 活动免费，报名需要审核。有问题可以在 X 或小红书找我（MaiYangAI）。 报名链接：

Grok Bot 邮箱太方便了，Bot 本身是不需要梯子就能用的，你可以通过它的邮箱帮你去注册本来要梯子才能注册的平台账号，去申请一些测试的额度等等，还没有的赶紧领一个～

Seriously, this actually works! Think of Grok @Bot like hiring a super smart employee who works 24/7 and is extremely resourceful. You can use it through your phone effortlessly within minutes:
