UnverifiedTests generated by Codex still require manual verification, as AI may misinterpret reproduction steps or write test cases that fail to accurately hit the bug; locally verifying that the test actually fails should be treated as a mandatory step.66% similarUnverifiedCodex CLI achieves autonomous iteration through a closed loop of reading code files, analyzing problems, executing modifications, running tests, and self-correcting based on results.65% similarUnverifiedThe test was broken by three different reviewers in succession, with the breakage targeting the test rather than the code, and each instance belonging to a different failure category.65% similarUnverifiedIn 724 prompt injection tests, Claude Code achieved zero breaches, but the tests were commissioned by Anthropic itself and lack independent third-party verification.63% similarUnverifiedIn the code review, Claude Code not only pointed out the ReDoS risk but also measured the time taken to quantify the impact, whereas Antigravity CLI also found the flaw but did not verify it.62% similar
