Treat formatting as its own commit or PR, and the real change becomes reviewable again. 3 min read · [blogs.powerduck.com](https://blogs.powerduck.com/agent-reformatted-whole-file-buried-diff?utm_source=hashnode&utm_medium=feed) [Powerduck](https://hashnode.com/@powerduck) · [Oct 25](https://hashnode.com/posts/agent-fills-missing-config-with-silent-default/6add4cf5a114ff52457170b6) ### [The agent filled the missing config with a default and the misconfiguration went quiet](https://blogs.powerduck.com/agent-fills-missing-config-with-silent-default?utm_source=hashnode&utm_medium=feed) The required region setting was unset, so the agent added a hardcoded fallback instead of failing fast. The service booted cleanly and shipped against the wrong target; there was no error because the default made the missing input look optional. 4 min read · [blogs.powerduck.com](https://blogs.powerduck.com/agent-fills-missing-config-with-silent-default?utm_source=hashnode&utm_medium=feed) [Powerduck](https://hashnode.com/@powerduck) · [Oct 24](https://hashnode.com/posts/agent-fixes-one-call-site-misses-sibling-pattern/6add3f4152cce888709ad527) ### [The agent fixed the failing call site and left the same bug on its sibling](https://blogs.powerduck.com/agent-fixes-one-call-site-misses-sibling-pattern?utm_source=hashnode&utm_medium=feed) The agent added a null guard to the exact route reported, tested that case, and closed the ticket. Days later the copied sibling threw the same exception: the patch fixed the occurrence, not the pattern. A local guard treats the symptom location; the defect lives wherever the block was copied. 4 min read · [blogs.powerduck.com](https://blogs.powerduck.com/agent-fixes-one-call-site-misses-sibling-pattern?utm_source=hashnode&utm_medium=feed) [Powerduck](https://hashnode.com/@powerduck) · [Oct 10](https://hashnode.com/posts/agent-refactors-out-forgotten-edge-case/6aca9ef60715f9bfa3175059) ### [Your Agent Will Refactor a Working Function and Quietly Drop the Edge Case](https://blogs.powerduck.com/agent-refactors-out-forgotten-edge-case?utm_source=hashnode&utm_medium=feed) The diff looks cleaner. The tests pass. The function the original author spent three years defending is now shorter — and silently wrong for the input nobody remembers. 3 min read · [blogs.powerduck.com](https://blogs.powerduck.com/agent-refactors-out-forgotten-edge-case?utm_source=hashnode&utm_medium=feed) [ZyVOP](https://hashnode.com/@zyvop) · [Oct 3](https://hashnode.com/posts/automate-your-code-quality-with-git-hooks-and-never-argue-in-code-review-again/6ac0ecc022dde8ffd71dff4d) ### [Automate Your Code Quality with Git Hooks (And Never Argue in Code Review Again)](https://blog.zyvop.com/automate-your-code-quality-with-git-hooks-and-never-argue-in-code-review-again?utm_source=hashnode&utm_medium=feed) Stop Catching Style Issues in Code Review — Your Editor Should've Flagged Them Before You Even Committed 9 min read · [blog.zyvop.com](https://blog.zyvop.com/automate-your-code-quality-with-git-hooks-and-never-argue-in-code-review-again?utm_source=hashnode&utm_medium=feed) [ZyVOP](https://hashnode.com/@zyvop) · [Sep 27](https://hashnode.com/posts/should-you-still-learn-to-code-now-that-ai-can-write-it/6ab8822f519a7faaee2ce8d4) ### [Should You Still Learn to Code Now That AI Can Write It?](https://blog.zyvop.com/should-you-still-learn-to-code-now-that-ai-can-write-it?utm_source=hashnode&utm_medium=feed) Nvidia's CEO says programming is obsolete.
