Vibing a Non-Trivial Ghostty Feature via Mitchell Hashimoto

A nice read from one of the greats on how he’s using LLM editor agents in late 2025. He touches on:

  • using specs for guidance
  • building documentation as support for edits
  • subagents for tasks
  • mixing user edits with agent edits

Inspired me to make my own oracle subagent to experiment with: https://github.com/joshbeckman/dotfiles/commit/b693656d6af646bab80390d68992e2996dece3ac
