Emacs (MOO)

What this skill is

GNU Emacs with emacs --daemon is a long-lived evaluator: buffers, modes, and elisp are the program. Agents and humans share persistent context (open files, marks, narrowing, undo). The sister script scripts/emacs.py adapts emacsclient for tools: JSON-shaped results, named targets, batching, logging, and emacs:// routing.

This is not a thin “run one shell command” wrapper. The value is the protocol: what to return after each operation, how to name multiple daemons, how speech and intent map to elisp.

Three interaction tiers

1. Intent — (moo-rename-symbol "a" "b" :scope 'project) style (to be implemented in elisp; names in CARD).
2. Structural — (moo-in-defun "foo" ...) , (moo-try BODY) with atomic-change-group.
3. Raw elisp — (emacs.py eval "(+ 1 2)") or direct emacsclient --eval.

Sister script: scripts/emacs.py

Subcommands (see --help):

• status — daemon up, current target
• eval SEXP — evaluate, print JSON {ok, value, error} where possible
• target list | current | use NAME — ~/.emacs.d/moo/servers.yml
• speak TEXT — placeholder: will use spoken-grammar.yml + optional local LLM
• url EMACS_URL — resolve and dispatch (staged implementation)

Environment:

• EMACSCLIENT — path to emacsclient (default: emacsclient)
• MOO_EMACS_TARGET — default target name

Logs: append JSON lines to .moollm/skills/emacs/logs/command-log.jsonl when run from a MOOLLM workspace.

Elisp side (templates/)

Install copies under ~/.emacs.d/moo/ (see templates/init.el):

• moo-protocol.el — moo-with-effects, standard result plist
• moo-structural.el — structural helpers
• moo-oneshot.el — oneshot define / log / promote
• moo-macros.el — macro capture and schema export hooks

Integration

• play-learn-lift — oneshot log + macro list + command-log.jsonl
• cursor-mirror — optional: correlate agent edits with Emacs log
• yaml-jazz — spoken-grammar.yml comments carry semantics

Cursor prompt / aiService snapshot

Optional: reference/cursor-aiService-prompts.yaml holds aiService.prompts and aiService.generations from the workspace DB (see reference/README.md). Regenerate with cursor-mirror export-prompts <workspace-id> -o ….
