I added AI-generated release notes to my CI/CD pipeline using Claude and GitHub Actions

Every time I merged a PR I had to write a changelog entry manually. It took two minutes but I kept forgetting to do it. So I automated it with Claude. When a PR merges to main, a GitHub Actions workflow reads the PR title, description, and changed files, sends them to the Claude API, and gets back a structured changelog entry. That entry gets committed to CHANGELOG.md automatically. The whole thi...

AI Coding Tools Raise the Ceiling for Developers, Not Replace Them

TL;DR: The Core Arguments * The Hallucination Tax: AI is architecturally optimized for confidence, not correctness. Your deep technical literacy enables you to audit the logic that ultimately runs your business. * The Prompting Ceiling: Your ability to guide an AI is capped by your technical vocabulary. Better engineering knowledge equals higher-leverage prompts. * The Sustainability Gap: AI ag...
