Harness engineering: Leveraging Codex in an agent-first world

https://images.ctfassets.net/kftzwdyauwt9/1Gu58eNlqDEuITmbqJDmq9/1e2e62f7e15fb16d2da0da5407240564/fig_1__codex_drives_the_app_.png?w=3840&q=90&fm=webp
We used Codex to generate a million lines of code for a software product in 5 months with a team of 7 engineers, achieving an average throughput of 3.5 PRs per engineer per day. To maintain the codebase, we focused on designing environments, scaffolding, and feedback loops that enable agents to do reliable work, enforcing invariants and mechanical rules to keep the codebase legible and consistent.

Moving beyond fork() + exec()

A recent Linux kernel proposal to add "spawn templates" to optimize the fork() and exec() pattern has been rejected, but it may point to a new process-creation primitive in the future. The discussion highlights the need for a better process-creation mechanism, with some suggesting a native implementation of posix_spawn() and others proposing alternative approaches using existing system calls.
