# cmux Resume Sessions > ⚠️ **Wrong skill?** If your sessions died from a crash / power loss / OOM kill, > use **`cmux-recover-sessions`** instead. That skill scans `.jsonl` files on > disk and finds sessions you never explicitly saved. Resume only works on a > JSON snapshot you produced earlier with `cmux-save-sessions`. ## Overview Restores cmux workspaces from a JSON snapshot saved by `cmux-save-sessions`. Restores workspace structure (name, cwd) and continues Claude Code conversations automatically. > **Role separation**: > - `cmux-resume-sessions` (this skill): Intentional restore from a JSON snapshot you saved on purpose (file-based) > - `cmux-recover-sessions`: Post-crash/power-loss recovery from `.jsonl` files Claude Code persists automatically (process-based) ## The Iron Law ``` RESUME RESTORES STRUCTURE AND CONTINUES CONVERSATIONS. ``` Resume restores workspace structure (name, cwd) and, per session, runs `claude --resume <session-id>` when the snapshot carries a session id — falling back to `claude --continue` (the cwd's most recent conversation) when it does not — to pick up the prior conversation in each directory. It does NOT restore runtime state of previously running commands or sessions. ## When to Use - Restore a workspace layout from a `cmux-save-sessions` snapshot - Rehydrate yesterday's working set at the start of a new day - Move a session layout to another machine (snapshot → transfer → resume) > **Not for crash recovery** — after a power loss
