They're everywhere. Stuck in loops, hallucinating file paths, confidently rewriting code that worked perfectly fine. I've been seeing dead agents for months - and I kept building with them anyway. After shipping real software with agentic coding tools, I hit a wall: the existing platforms weren't cutting it. So I did what any reasonable developer would do - I built my own. Along the way I discovered patterns that actually work, experienced spectacular failures worth learning from, and... something I didn't expect: our libraries, frameworks, and tools weren't built for a world where an AI is the one reading the docs, writing the code, and running the tests. Imagine what the Elixir ecosystem would look like if we reshaped it to meet the needs of agentic coding tools. Whether you're AI-curious or already elbow-deep in agent output, you'll leave with practical advice and a fresh lens on how to bend your favorite stack to this moment.
