Cheap code means formal verification is reasonable now
The article discusses the use of coding agents and formal verification to improve software development processes. It highlights the benefits of using TLA+ for modeling complex systems and finding bugs like race conditions. The author shares insights on how to effectively utilize these tools to enhance code reliability and performance.
- ▪Coding agents can optimize code by checking against comprehensive test suites.
- ▪TLA+ is a formal specification language that helps model complex systems and find bugs.
- ▪Using coding agents with TLA+ can significantly reduce the cost of formal verification.

Back to BlogMay 6, 2026Cheap code means formal verification is reasonable nowHow we use TLA+ and coding agents to formally model distributed systems, find race conditions, and turn speculative bug hunts into verified fixes.By Rowan Copleytla+formal-verificationai-agentsdistributed-systemsbug-huntingIt would be an understatement hardly worth uttering to say that coding agents are a big deal. But using them most effectively isn't exactly as simple as telling Claude to build you a SaaS product and make no mistakes. Collectively, as software engineers (or whatever you call this job these days), it's up to us to find ways to be most effective with them while minimizing harm to what we're building. One of the best techniques I know is having your agent hill climb on verifiable problems.
