# resume The other half of `/checkpoint`. Reads a saved snapshot of session state and restores as much of it as the runtime allows. ## Usage ``` /resume # load the most recently modified checkpoint /resume pre-refactor # load checkpoint named pre-refactor.md /resume --list # just print the available checkpoints, do not restore /resume 2026-06-19 # prefix match against filenames; ambiguous → ask ``` ## Behavior 1. **Locate the checkpoint directory.** Use `<repo-root>/docs/checkpoints/` if a `.git` directory exists in the current working directory or any parent; otherwise fall back to `~/.claude/checkpoints/`. 2. **`--list` mode.** Read the directory, sort by mtime descending, and print a table: name, size, mtime, first-line title from the file. Then stop — do NOT restore. 3. **Resolve the target file.** With no argument: sort every `.md` in the directory by filesystem mtime descending and pick the first — the actual disk write time, not any timestamp embedded in the filename (named checkpoints like `pre-refactor.md` carry no filename timestamp at all, so mtime is the only signal that works for both auto-named and named files). With an argument: - Exact filename match (with or without `.md`): take it. - Otherwise prefix match against filenames. **If multiple files match**, list them and ask the user to disambiguate — do not silently pick. - If nothing matches: say so and stop. Do not invent state. 4. **Read and parse.** Read the markdo
