🚀 Claude Code Quick Start Guide

📋 What We're Building

A professional Claude Code environment using:

Docker for isolated development environments
Node.js 24 for running Claude Code
Git for version control, zsh for better UX
Claude Code Router for more cost-effective agentic coding

Core Rules (Always Active)

Context

You are assisting an experienced technical product manager at Spotify. Most questions require Spotify internal knowledge - use MCP servers to fetch internal documentation when needed. Provide Spotify internal links and references when applicable.

Core Behavior

You are an agent - keep going until the query is completely resolved
If unsure about file content or Spotify context, use tools to gather information - don't guess
Plan extensively before function calls and reflect on outcomes
Be concise and use Markdown for non-code responses

Instantly Translate or Correct Clipboard Text into German with Raycast + OpenAI

This Raycast Script Command lets you instantly translate and correct any text (poor German, English, Dutch, etc.) into grammatically correct German — triggered by a shortcut on macOS.

The script:

Reads the current clipboard text
Checks if the clipboard contents don't look like a password
Sends it to OpenAI's GPT-4 Turbo model
Receives corrected German

Building an AMD64 Docker Image on ARM-based Mac

This guide documents the successful process for building an AMD64-compatible Docker image on an ARM-based Mac.

Prerequisites

Docker Desktop with buildx support installed
ARM-based Mac (M1, M2, etc.)
A Docker buildx builder for AMD64 architecture

	#!/bin/bash

	# Required parameters:
	# @raycast.schemaVersion 1
	# @raycast.title Prompt my prompt
	# @raycast.mode silent

	# Optional parameters:
	# @raycast.icon 🤖
	# @raycast.packageName Prompt Tools

	# bootstrap_devbox.sh (Ubuntu 24.04 LTS)
	# Run once as root: sudo bash /tmp/bootstrap_devbox.sh
	set -euo pipefail

	# ===== Config (edit as needed) =====
	TZ="Europe/Berlin"
	# Auto-detect first non-root login; override by exporting TARGET_USER before running
	TARGET_USER="${TARGET_USER:-$(logname 2>/dev/null \|\| getent passwd 1000 \| cut -d: -f1)}"
	TARGET_HOME="$(getent passwd "$TARGET_USER" \| cut -d: -f6)"
	DOCKER_REMOTE_HOST="${DOCKER_REMOTE_HOST:-docker-host.local}" # e.g., docker-host.lan

	### Process Flow
	- ASK FIRST: When missing information or context before starting implementation, always ask the user for clarification
	- TDD SEQUENCE: Always follow this exact sequence: write test → create code → verify all tests pass → git commit
	- USE FULL PATHS: When executing commands, always use full paths, never relative paths. Do not assume you're in the project directory

	### Testing Constraints
	- 10-SECOND TIMEOUT: All unit tests must have timeouts. Test suites must not exceed 10 seconds total runtime
	- NO STUCK TESTS: Implement timeouts to prevent AI agent from getting stuck on hanging tests

	### Dev Rules

	#!/usr/bin/env python3
	import json
	import re

	# Convert Youtube subtitle to txt file
	#
	# Look for `https://www.youtube.com/api/timedtext` in your browser network tab
	# on a youtube video. Copy the response into a subtitle.json file and save this
	# script in the same folder.

	services:
	couchdb:
	image: couchdb:latest
	container_name: obsidian-livesync
	# user: 1000:1000 # You may need to adjust this depending on your host system's user/group IDs for file permissions
	environment:
	- COUCHDB_USER=${COUCHDB_USER}
	- COUCHDB_PASSWORD=${COUCHDB_PASSWORD}
	volumes:
	- /docker/volumes/obsidian-livesync/data:/opt/couchdb/data

	# MacBook Migration Script
	#
	# A simple script to move over your important stuff.
	# I'm assuming you'll install the necessary tools and packages with something else.
	#
	# Prepare your mac before running this:
	# 1. Enable SSH access on your old machine
	# 2. Go to System Settings > Privacy & Security > Full Disk Access
	# and enable it for "sshd-keygen-wrapper"
	# 3. On your new mac, download this script and make it executable by running
