Along with hill climbing, evals also explicitly capture and protect against regressions over time. Once our agent handles a case correctly, we don't want to lose that gain. The eval becomes a regressi

experimentation and A/B testing" — Copy-on-write forking enables trivial A/B testing by allowing isolated collection variants without performance overhead

Start Development: Launch Inspector with your server. Verify basic connectivity. Check capability negotiation. Iterative testing: Make server changes. Rebuild the server. Reconnect the Inspector." — A

The bottleneck is no longer generation. It's verification. Agents can produce impressive output at incredible speed. Knowing with confidence whether that output is correct is the hard part." — Article

at the end of the day, you just check if everything looks good in the next branch and ship that to main" — Article describes validating multiple merged PRs at once before shipping to production, reduc

Also I need you, once you've fixed and verified each of those problems is completely resolved and working properly, to create extremely in-depth e2e integration tests that would have caught each of th

There was a subtle bug that missed several rounds of manual review. We're working on how we can better catch it automatically next time." — Highlights gap in manual code review catching subtle bugs an

All tests are now passing! The refactoring was successful." — Article demonstrates validation of changes through comprehensive test suite execution (800 tests)

The key is to use AI to save some time, then spend enough time checking the work carefully" — Article advocates for human review and careful checking as essential guardrail against AI-generated errors

The software I'm creating nowadays is vastly more robust than I'd ever been able to create manually. I don't mean that the code is better. I mean the surrounding tests are vastly better." — Evidence t
