# sync-add-note — leave a cross-device reminder Records a note in the shared sync folder. It surfaces on the user's *other* machines the next time they run `/sync-env-down`, never on the machine that made it. The engine (`sync_engine.py`) lives in the sibling `sync-envs` skill folder. ## How to run the engine - **Windows:** `py -3 "<claudeSkillsDir>\sync-envs\sync_engine.py" --add-note "TEXT"` - **macOS/Linux:** `python3 "<claudeSkillsDir>/sync-envs/sync_engine.py" --add-note "TEXT"` **Run it in the background** (the Bash tool's `run_in_background: true`) — it writes to the sync folder, which is usually a cloud drive; see the timing note in `/sync-env-down` if it stalls. ## Procedure 1. **Get the note text.** Use what the user gave after `/sync-add-note`. If they just invoked the skill with no text, ask what they want to remember. Keep it a single, self-contained reminder — enough to act on from another machine with no memory of this conversation. Split multiple unrelated reminders into separate `--add-note` calls. 2. **Heads-up on content.** Notes are stored as **plaintext** in the sync folder. Don't put secrets (tokens, passwords) in a note; if the user's text contains one, flag it and suggest leaving the secret out. 3. **Add it.** Run the engine with `--add-note "TEXT"`. Quote the text; it may contain spaces. 4. **Confirm.** Relay the engine's confirmation, including the note id, and remind the user it will show up on their other machines on t
