Karabiner-Elements rules for Deutsch (ADNW) keyboard layout on macOS

Fixes and ergonomic shortcuts for using the ADNW keyboard layout on macOS with Karabiner-Elements.

Problem

Custom keyboard layouts like ADNW define a command keymap that remaps keys when Cmd is held. This causes issues:

• Chrome's Cmd+Shift+T (Reopen Closed Tab) breaks because keycode 17 maps to a-umlaut instead of t in ADNW's command keymap
• Other shortcuts need remapping to match ADNW's ergonomic key positions

Fix Shift+Enter for Claude Code (and other CLI tools) in Hyper Terminal

The Problem

Hyper terminal (powered by xterm.js) sends the same byte (\r, carriage return) for both Enter and Shift+Enter. This means Shift+Enter can't insert a newline in Claude Code's multi-line input - it just submits instead.

Other terminals like iTerm2, Kitty, Ghostty, and Alacritty either handle this natively or have simple config options. Hyper doesn't, but a small local plugin fixes it.

The Fix

#!/bin/bash
# Claude Code "Stop" hook: completion sound + smart TTS announcement (macOS)
#
# - Always plays a sound when Claude Code finishes
# - Announces the project name via TTS only if you're NOT focused on that project's window
# - Uses git repo root name as project name (falls back to folder name)
#
# Setup:
# 1. Save this script to ~/.claude/hooks/done-announce.sh
# 2. chmod +x ~/.claude/hooks/done-announce.sh

Messaging tools for a personal agent (macOS)

Read-only-by-default scripts that let Claude Code (or any agent with shell access) actually run your messaging: read threads across every platform, work out where a person is reachable, and send with guardrails that stop the classic agent failures.

I used these to schedule ~40 coffees and dinners for a week in SF: the agent read each thread, drafted a reply in my voice, showed it to me, and sent it on whatever platform that person actually uses.
