# Emacs Testing > Test changes in a dedicated Emacs session. Good for validating behavior and UI results. Use when this capability is needed. - Skill: `tomevault-io/emacs-testing` (Agent Skill, multi-file: 2 files) - Install (CLI): `npx skillmds@latest add tomevault-io/emacs-testing` - Raw SKILL.md: https://api.skillmd.com/api/skills/tomevault-io/emacs-testing/raw - Safety review: pending (external: skill-scanner PASS, skillspector PASS) - Works with: Claude Code, Claude.ai, OpenAI Codex - Category: Coding & Dev Tools - Author: tomevault-io (https://skillmd.com/u/tomevault-io) - Updated: 2026-09-17 - Page: https://skillmd.com/skills/tomevault-io/emacs-testing --- Before starting, you MUST ask me if you have permission to test in the existing Emacs server. If not, start a new Emacs daemon server: `emacs --daemon=kele-testing`. Send commands to the Emacs with: `emacsclient --eval`. If I did not give permission to run in the existing server, use `emacsclient -s kele-testing --eval`. If you created a separate daemon server, terminate it once you are done testing. --- > Source: [jinnovation/kele.el](https://github.com/jinnovation/kele.el) — distributed by [TomeVault](https://tomevault.io).
