Compound Engineering is what happens when agents write 100% of the code. At @every, engineers don’t type code anymore. They orchestrate agents. The shift: - Coding is no longer the bottleneck - Planning, review, and learning loops matter more than syntax - Each feature makes the next one easier to build The 4-step Compound Engineering loop: 1.Plan – Agents research the codebase + best practices and produce detailed plans http://2.Work – Agents write code, tests, and iterate using real app simulations 3.Assess – Humans + AI review from multiple angles (security, performance, overbuild) 4.Compound – Lessons learned are stored so future agents never repeat mistakes Complexity still grows, but so does the AI’s understanding of the system. Result: - One developer can now do the work of ~5 - Products run by single engineers serve thousands of users - New hires instantly inherit years of institutional knowledge Engineering is no longer about writing code. It’s about designing learning systems that compound. — Thanks @danshipper and @kieranklaassen for sharing your approach. So much to learn and takeaway from this compound engineering approach.
