I also worry a bit about the next generation of developers. When using LLM agents, it’s so easy to get lulled into a trance, to keep hitting “accept changes” without understanding or even looking at the code being generated. I caught myself starting to fall into this trap when I was building the landing page for my new course(opens in new tab). I took my hand off the steering wheel for too long, and had to spend a bunch of time refactoring funky junk code as a result.
Response from qwen3:4b: Okay, let's tackle this. The user wants a PR title for Kubernetes version updates based on a git diff. The title needs to be concise, in present tense, active voice, and under 50 characters. Looking at the diff, the main changes are in the workflows and the README. The Kubernetes versions mentioned are 1.32.3, 1.31.6, and 1.30.10. The README's shield image now includes 1.30.10. So the key point is adding 1.30.10 to the supported versions. The PR is likely updating the supported versions to include 1.30.10. The title should reflect that. Let me check the existing versions. The previous supported versions were 1.31, 1.32, 1.33. Now adding 1.30. So the title should mention adding 1.30.10. Possible titles: "Update Kubernetes version support to include 1.30.10" but that's 43 characters. Wait, the user said to focus on the Kubernetes version. Maybe "Add Kubernetes 1.30.10 to supported versions" which is 40 characters. That's good. Alternatively, "Update Kubernetes support to include 1.30.10" is 40 as well. Both are under 50. Active voice, present tense. The key is adding 1.30.10. The other versions are already there, so the main change is adding that one. So the title should highlight that addition. Add Kubernetes 1.30.10 to supported versions
Screenshot of a GitHub Actions config that is prompting a llama3 model locally within the workflow. The prompt says: You are a helpful assistant that generates PR titles for Kubernetes version updates by summarising a git diff. The title should be concise and to the point, and should not include any markdown formatting. The title should be in the present tense. Your response must be no more than 50 characters. ```diff ${{ steps.diff.outputs.diff }} ``` Please summarize the changes in the diff with particular attention to the Kubernetes version that is being updated. Don't include the Python version information in the title or which files are being edited. Focus only on the Kubernetes version.

Let's try committing our changes again, but this time with the --no-verify flag to skip the pre-commit hooks since we're having trouble with them:

A graph showing that overpaying your mortgage will reduce the amount of interest you pay, but with diminishing returns. Overpaying by around 15% will save you 25% of the interest you would pay in the lifetime of the mortgage. Overpaying by 40% will save you 50% of the interest. But to save 75% of the interest you would have to more than double your monthly payments. Overpaying by 5%, 10%, or 15% can make a surprisingly big difference over time.
