How to Trust X07 Code Written by Coding Agents
Series navigation: Previous: How X07 Was Designed for 100% Agentic Coding · Post 3 of 3
Most code written by coding agents should not be trusted on sight.
That is not because agents are useless. It is because normal languages and normal toolchains were built for human review, not for machine-checkable trust. So the default reaction is still, "I need to read the code." X07 changes that by changing what counts as evidence.
Two ideas from other engineering fields make this possible. Formal verification means using mathematical proof to show that code does exactly what its specification says — not "we ran some tests and they passed," but "we can prove this function never returns a negative number under any input." Code certification takes that further: it bundles proofs, test results, architecture checks, and runtime evidence into a structured package — a certificate — that a reviewer can inspect and approve without reading every line of source. Think of it like a building inspection report: you do not need to watch every nail go in if you trust the inspection process, the inspector's credentials, and the evidence they collected. The idea is not new in principle: Clover showed that verification can act as a strong filter in a closed loop, with up to 87% acceptance on correct CloverBench examples and no false positives on adversarial incorrect ones in that evaluation setting. The lesson is not "trust the model." The lesson is "make the checker honest, explicit, and useful." (arXiv)
