Memory Sync

Sync your Zettelkasten cards across devices using git.

Tools Available

memex sync --init <url> — initialize sync with a git remote
memex sync --init — auto-create a private GitHub repo via gh CLI
memex sync — pull remote changes, commit local changes, push
memex sync --status — show sync configuration and last sync time
memex sync on|off — enable/disable auto-sync after every write/archive

Process

digraph sync {
    "User invokes /memex-sync" -> "memex sync --status";
    "memex sync --status" -> "Configured?" [shape=diamond];
    "Configured?" -> "memex sync" [label="yes"];
    "Configured?" -> "Ask user for repo URL" [label="no"];
    "Ask user for repo URL" -> "User provides URL?" [shape=diamond];
    "User provides URL?" -> "memex sync --init <url>" [label="yes"];
    "User provides URL?" -> "memex sync --init (auto-create via gh)" [label="no, use gh"];
    "memex sync --init <url>" -> "Report success";
    "memex sync --init (auto-create via gh)" -> "Report success";
    "memex sync" -> "Report result";
}

Step 1: Check status

Run memex sync --status to see if sync is already configured.

Step 2: Initialize (if needed)

If sync is not configured:

Ask the user if they have a git repo URL for their cards
If yes: memex sync --init <url>
If no: memex sync --init (auto-creates a private memex-cards repo on GitHub via gh CLI)

Step 3: Sync

If already configured, run memex sync to push and pull changes.

Step 4: Report

Tell the user the result. If sync failed, show the error message.

Rules

Never force-push — memex sync uses git fetch + git merge then git push
On conflict — report the error and tell the user to resolve manually in ~/.memex
Auto-sync — only suggest memex sync on if the user asks about it; don't enable by default
