I've shared the full transcript of every agentic coding session from implementing the unobtrusive Ghostty updates and provided commentary alongside about my thinking and process.

I'm regularly asked to share non-trivial examples of how I use AI and agentic coding tools and this felt like a golden opportunity to walk through my process with a well-scoped, non-trivial, real-world, shipping feature.

Total cost: $15.98 over 16 sessions.

@mitchellh I finally had an opportunity to do some agentic coding for the first time myself this weekend and was pleasantly surprised by the results.

I had a small problem to solve and asked Copilot to do a simple file import for me to get started because I never remember how to do it. That step went so well I ended up spending the day having Copilot write the whole utility for me, including refactoring, tests, and docs.

Thanks for sharing. Nice to compare my own experience with yours!
