Btw, for Ghostling (libghostty demo), I didn't write a single line of... anything. Agents wrote 100% of everything you see incl. Nix flakes, CI jobs, etc. I reviewed every line of code manually and constantly nudged the agents in the right direction. I used a mix of Opus+Codex.

I went from empty repo to functional terminal that could run Neovim with keyboard, mouse events in ~80 minutes. Pretty sweet.

Note: libghostty itself is of course heavily hand written (with agent assistance all over too, though). I'm just talking about Ghostling itself.

Even for CI setup (GitHub actions), I had the agent sit in a `gh` CLI loop watching failures, fixing, pushing, fixing, pushing, etc. Doing GHA with agents are the only way I stay sane, honestly.

I just re-read the full main.c from top to bottom and I'm very satisfied. I would've done some things differently but if an engineer I worked with PRed all this, I would've accepted it. Its good enough.

Some people have pointed out the commenting is over the top and indicative of AI. This is actually my personal comment style, and I told the agent to comment heavily (its even in the AGENTS.md, look for yourself!). Anyone who has worked with me professionally or in OSS knows that I comment everything all the time.
