- What they did
- Every area of the author's life and business gets a Johnny.Decimal ID, tied to an index entry in an Obsidian vault, Markdown notes, and a disk folder. A CLI plus agent skills map those links. Running jd with an ID or title search launches Claude in the matching folder, where it reads the index notes and keeps its own memory and transcripts.
- How it went
- Claude can read the human-readable notes and use --resume to pick up past conversations for that piece of work. The author calls it a solved problem. No measured results are given.
- Worth knowing
- Setup is free and takes about half an hour; the author's MCP server adds conveniences but is paid. The numbering scheme itself isn't required.
Try it yourself with Claude Code
I keep project notes as an Obsidian Markdown vault at [path to vault], with an index note for each [client or project]. Set up a small CLI or script plus a skill so that when I launch you from a folder named with a project ID like [example ID], you find the matching index note, read it, and summarize where we left off, including the last session's decisions and open tasks. Done when I can start you in two different project folders and each one loads the right context. Show me the files you plan to create before writing them, and don't modify my existing notes.
