From jylhis-skills
Use for Emacs and Emacs Lisp work — modern Elisp conventions (lexical-binding, use-package, keymap-set, setopt, defvar-keymap, if-let*, tree-sitter ts-mode), authoring major modes (define-derived-mode, font-lock, indent-line-function, syntax tables, treesit-simple-indent-rules), package publishing (MELPA / GNU ELPA / NonGNU ELPA, ;;;###autoload, package-lint, checkdoc), code review (linting, byte-compile, obsolete API detection), ERT testing, debugging (--debug-init, Edebug, profiler, native-comp), gptel + MCP integration, introspection (describe-*, apropos, find-function), and keybinding design (keymap layers, key-valid-p). Read the matching reference before acting.

For Emacs packaging via Nix (emacsWithPackages, melpaBuild,
trivialBuild, native-comp, tree-sitter grammars), use the nix skill's
references/emacs-packaging.md instead.
After reading the reference, follow its guidance for the task.
