# Resume From the caller's original working directory, find the repository with `git rev-parse --show-toplevel`. Refuse outside a Git repository. Read only `<repo-root>/docs/checkpoints/`; never use a shared home-directory fallback. - `--list`: show each `.md` checkpoint's name, size, modification time, and first-line title, newest first. Stop without restoring. - No argument: choose the `.md` file with the newest filesystem modification time, including named checkpoints. - Name or prefix: prefer an exact filename (with or without `.md`), then a unique prefix. If ambiguous, list matches and ask the user. If absent, say so; do not invent state. Read the selected file, tolerating hand edits. Lead with its `Session summary`, then surface open questions and decisions. Recreate unfinished tasks and dependencies only if task tools exist; if live tasks already exist, ask before merging or replacing them. Restate any saved goal and use a goal tool only when one is available and the user's intent permits it; otherwise give the user the text to resume manually. Warn when the checkpoint is older than seven days. Do not modify the checkpoint, repository, or Git state.
