# Worktree List List all active worktrees with rich context: branch, status, sync state, and staleness detection. **User input:** $ARGUMENTS ## Step 1 — Gather worktree data ```bash git worktree list --porcelain ``` Parse the output to extract for each worktree: - **Path** (`worktree <path>`) - **HEAD commit** (`HEAD <sha>`) - **Branch** (`branch refs/heads/<name>`) or `(detached HEAD)` Identify the main working tree (first entry) and label it as such. If there are no worktrees beyond the main working tree, report: > No additional worktrees found. Use `/wt-open` to create one. Then stop. ## Step 2 — Enrich each worktree For each worktree, gather the following: ### Clean/dirty status ```bash git -C "<path>" status --porcelain 2>/dev/null | wc -l | tr -d ' ' ``` - `0` → "clean" - `>0` → report count of modified files ### Ahead/behind remote ```bash git -C "<path>" rev-list --left-right --count @{upstream}...HEAD 2>/dev/null ``` Output format: `<behind>\t<ahead>`. If no upstream is set, note "no remote". ### Last commit ```bash git -C "<path>" log -1 --format="%cr|%s" 2>/dev/null ``` This gives relative time and subject (e.g., `2 hours ago|add session store`). ### Staleness check ```bash git -C "<path>" log -1 --format="%ct" 2>/dev/null ``` Compare the commit timestamp to now. Flag as **stale** if the last commit is **3 or more days old**. ## Step 3 — Format the output Present each worktree as a block, for example: ```text Active worktrees: main (ma
