An autonomous coding system built a database engine and passed 6 million SQLite tests
jiayq · x · 2026-07-29
The post describes an autonomous coding system that can build a database engine from a one-line prompt and keep working until it passes all 6 million SQLite compatibility tests.
- It starts from zero existing docs or code.
- The system performs the roles a strong team would normally split across architecture, coding, testing, review, and QA.
- A related example shows a fast file system built for an agent-first world, where formal verification caught and fixed a transient corrupted-state bug in a coding agent.
