Set up my Claude Code status line to be an exact copy of a specific design. Use the `/statusline` command to do this — it pulls Claude Code's built-in **statusline-setup** skill that configures the status line setting. But transcribe the script below **verbatim**; do NOT improvise, redesign, or invent your own version. **IMPORTANT — this must fully replace whatever is already there.** Three cases, all handled the same way: 1. **Nothing configured yet** → install fresh. 2. **A different custom status line configured** in `~/.claude/settings.json` (or anywhere else) → remove/overwrite it. 3. **An older version of _this_ status line already installed** — recognizable by the 20-char `█░` bar and mood emoji, but with either no worktree section at all, or a bare ` 🌳` with no worktree name after it → **overwrite the entire script file; do NOT patch or hand-edit the old copy.** Older revisions drift in small ways, so the only acceptable end state is that `~/.claude/statusline-command.sh` matches the script below exactly. When you're done there must be exactly one `statusLine` config in `~/.claude/settings.json`, exactly one status line script, and it must be this one. Steps: 1. Make sure `jq` is installed (it's required — without it the bar silently won't render). Check with `command -v jq`. If missing, install it (macOS: `brew install jq`; Debian/Ubuntu: `sudo apt-get install -y jq`). 2. Write this EXACT content to `~/.claude/statusline-command.sh` (create the `~/.claude` dir if needed), then `chmod +x` it. If the file already exists, **truncate and rewrite it wholesale** — do not merge, append, or surgically edit the worktree block of an older copy: ```bash #!/usr/bin/env bash input=$(cat) # ── Model detection ────────────────────────────────────────── # Claude Code sends the model as an OBJECT (.model.id). Hand-made or older # payloads may send a plain string, so handle both without erroring out. model_id="${CLAUDE_MODEL_ID:-}" if [ -z "$model_id" ]; then model_id=$(echo "$input" | jq -r 'if (.model|type)=="object" then (.model.id // empty) else (.model // empty) end') fi model_lower=$(echo "$model_id" | tr '[:upper:]' '[:lower:]') # Context size is read from the payload, never hardcoded per model — the same # model ships in different window sizes (e.g. Sonnet 200K vs Sonnet 1M), so # guessing from the name gets both the label and the "free" count wrong. total_tokens=$(echo "$input" | jq -r '.context_window.context_window_size // empty') case "$total_tokens" in ''|null|*[!0-9]*) total_tokens=200000 ;; esac if [ "$total_tokens" -ge 1000000 ]; then ctx_label="$(( total_tokens / 1000000 ))M" elif [ "$total_tokens" -ge 1000 ]; then ctx_label="$(( total_tokens / 1000 ))K" else ctx_label="${total_tokens}" fi if echo "$model_lower" | grep -q "opus"; then model_label="Opus ${ctx_label}" elif echo "$model_lower" | grep -q "sonnet"; then model_label="Sonnet ${ctx_label}" elif echo "$model_lower" | grep -q "haiku"; then model_label="Haiku ${ctx_label}" elif echo "$model_lower" | grep -q "fable"; then model_label="Fable ${ctx_label}" else model_label="Claude ${ctx_label}" fi # ── Context window ─────────────────────────────────────────── remaining=$(echo "$input" | jq -r '.context_window.remaining_percentage // empty') bar="" face="" if [ -n "$remaining" ]; then pct=$(printf "%.0f" "$remaining") # Free tokens (human-readable) free_tokens=$(( total_tokens * pct / 100 )) if [ "$free_tokens" -ge 1000000 ]; then free_label="$(( free_tokens / 1000 ))K" elif [ "$free_tokens" -ge 1000 ]; then free_label="$(( free_tokens / 1000 ))K" else free_label="${free_tokens}" fi # Color zone based on remaining % # Green > 20% — safe # Amber 10-20% — approaching compaction # Red < 10% — compaction imminent if [ "$pct" -gt 20 ]; then color="\033[32m" # green elif [ "$pct" -ge 10 ]; then color="\033[33m" # yellow / amber else color="\033[31m" # red fi reset="\033[0m" dim="\033[90m" # 20-char wide bar width=20 filled=$(( pct * width / 100 )) [ "$filled" -gt "$width" ] && filled=$width empty_count=$(( width - filled )) filled_str="" empty_str="" for ((i=0; i/dev/null) git_common_dir=$(git -C "$dir" rev-parse --git-common-dir 2>/dev/null) if [ -n "$git_dir" ] && [ -n "$git_common_dir" ] && [ "$git_dir" != "$git_common_dir" ]; then worktree_out=" 🌳" # Name the worktree by its root folder (the worktree's directory name) worktree_name=$(basename "$(git -C "$dir" rev-parse --show-toplevel 2>/dev/null)") [ -n "$worktree_name" ] && worktree_out="${worktree_out} ${dim}${worktree_name}${reset}" fi fi # ── Assemble output ────────────────────────────────────────── output="${model_label}" [ -n "$bar" ] && output="${output} ${bar}" [ -n "$face" ] && output="${output} ${face}" [ -n "$worktree_out" ] && output="${output}${worktree_out}" printf "%b" "$output" ``` 3. Wire it into `~/.claude/settings.json`. PRESERVE all my other existing settings — only add or replace the top-level `statusLine` key (replacing any status line I already had). Use my real absolute home path (run `echo $HOME` to get it; do not hardcode someone else's username): ```json "statusLine": { "type": "command", "command": "bash /.claude/statusline-command.sh" } ``` If `settings.json` doesn't exist, create it as valid JSON containing just that key. If it exists, merge carefully so the rest of the file is untouched and any previous `statusLine` is overwritten. 4. Confirm it works. Run every check below and show me the output of each. **Base line** — pipe a sample payload through the script, using the real shape Claude Code sends (`.model` is an object, and the window size comes from `.context_window.context_window_size`): ```bash echo '{"model":{"id":"claude-opus-5[1m]"},"context_window":{"remaining_percentage":82,"context_window_size":1000000}}' | bash ~/.claude/statusline-command.sh ``` It should print: `Opus 1M ████████████████░░░░ 82% 820K free 😄` **Sizing check** — the context size must come from the payload, not the model name. Same model, smaller window, and a different model at 1M: ```bash echo '{"model":{"id":"claude-opus-5"},"context_window":{"remaining_percentage":82,"context_window_size":200000}}' | bash ~/.claude/statusline-command.sh echo '{"model":{"id":"claude-sonnet-5"},"context_window":{"remaining_percentage":82,"context_window_size":1000000}}' | bash ~/.claude/statusline-command.sh ``` These must print `Opus 200K … 164K free` and `Sonnet 1M … 820K free` respectively. If either shows the wrong size, the script is guessing from the model name instead of reading the payload — go back and fix it. **Worktree branch** — the 🌳 and the name only appear when the current directory is an actual linked git worktree, so the payload above won't show them. To verify that branch, run it from inside a worktree (or feed a worktree path in), e.g.: ```bash echo '{"model":{"id":"claude-opus-5[1m]"},"context_window":{"remaining_percentage":82,"context_window_size":1000000},"workspace":{"current_dir":"'"$(pwd)"'"}}' | bash ~/.claude/statusline-command.sh ``` When `current_dir` is a linked worktree it should append ` 🌳 ` to the end of the line, with the name dimmed — e.g. `Opus 1M ████████████████░░░░ 82% 820K free 😄 🌳 feature-auth`. If I don't have a worktree handy, make a throwaway one to prove the branch fires, then clean it up: ```bash git worktree add /tmp/wt-check -b wt-check 2>/dev/null echo '{"model":{"id":"claude-opus-5[1m]"},"context_window":{"remaining_percentage":82,"context_window_size":1000000},"workspace":{"current_dir":"/tmp/wt-check"}}' | bash ~/.claude/statusline-command.sh git worktree remove /tmp/wt-check --force && git branch -D wt-check ``` **Negative check** — confirm it stays quiet where it should. Against a normal (non-worktree) directory it must print NO 🌳 and no folder name: ```bash echo '{"model":{"id":"claude-opus-5[1m]"},"context_window":{"remaining_percentage":82,"context_window_size":1000000},"workspace":{"current_dir":"'"$HOME"'"}}' | bash ~/.claude/statusline-command.sh ``` The expected status line format is: ``` % free [🌳 ] ``` The worktree segment is conditional — it appears **only** inside a linked git worktree. In a repo's main working tree, or in a non-git directory, nothing is appended. There is deliberately no always-on "current project" indicator.
