■ SUPPORT
Message the shop through Etsy if a file will not open or you find an error. Please don't send passwords or API keys.
• The practice bug files need Node.js 20 or newer; run node --version to check, then run each file with node <filename>.
• Error message wording can differ slightly between Node.js, Python and browser versions; match on the error code (such as ENOENT or TS2339) when the sentence differs.
• Claude Code commands and menus described in the guide were checked in October 2026; if something looks different, the official Claude Code documentation is the source of truth.
• Each solution file prints "Self-check passed." when it runs correctly; if you adapt one and an assertion fails, Node prints the expected and actual values to compare.

■ GOOD TO KNOW
• Software, prices and plan names change. Pages marked "Version note" tell you what to re-check against official documentation.
• No income, ranking or business result is promised or implied.
• Made with AI assistance: the content was drafted with Claude, and the product was designed and assembled by ClaudeEverything.
• ClaudeEverything is an independent publisher and is not affiliated with, endorsed by, or sponsored by Anthropic. Claude and Claude Code are Anthropic products and trademarks of their owner.
