Yak Power-Shears: LLMs are pretty good at Emacs
Summary
An Emacs veteran writes about using LLMs (Gemini and Claude) to build Emacs Lisp tooling, including a tree-sitter grammar for Cedar policy language, a function to extract backtraces from JSON logs, and syntax highlighting for Go test logs. The author shares redacted work logs and an Elisp code snippet that defines faces and a font-lock rule, plus notes on using Claude Code and Gemini. The piece emphasizes that LLMs can shave the yak of manual customization, but reviewers should understand the output before dropping it into .emacs, and it suggests applying similar ideas to Neovim or VSCode.
