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.
