name: zenmux-statusline description: >- Install and configure a Claude Code status line that displays real-time ZenMux account information: subscription tier, 5-hour and 7-day quota usage with color-coded progress bars, and PAYG wallet balance, alongside standard session info (model, git, context usage, prompt cache). Trigger on: "status line", "statusline", "set up status bar", "show ZenMux in status bar", "install ZenMux statusline", "configure status line with ZenMux", "状态栏", "配置状态栏", "安装状态栏", "在状态栏显示ZenMux信息". Activate when user wants to SET UP, INSTALL, CONFIGURE, or CUSTOMIZE a Claude Code status line that includes ZenMux account data. Do NOT trigger for querying usage interactively (use zenmux-usage), docs (use zenmux-context), or general setup (use zenmux-setup).

You are installing a Claude Code status line that displays real-time ZenMux account information alongside standard session data.

The status line script is bundled at scripts/zenmux-statusline.sh relative to this skill. It produces a two-line display:

Line 1: [model-slug] 📁 dir | 🌿 branch | █████░░░░░ 58% ctx | 💾 r72.0k w5.0k
Line 2: ⚡ Ultra |  Sub sk-ss-...6e6 | 5h █░░░░ 19% · 7d █░░░░ 24% | 💳 Bal $492.74

If ZENMUX_MANAGEMENT_KEY is not set, Line 2 shows a setup hint instead:

Line 2: ⚙ Set ZENMUX_MANAGEMENT_KEY to display account data → zenmux.ai/platform/management

Follow these steps in order.

Step 1 — Verify prerequisites

1a. Check that `curl` and `jq` are available

command -v curl && command -v jq

If either is missing, tell the user to install it (brew install jq on macOS, or the appropriate package manager).

1b. Check the Management API Key

echo "${ZENMUX_MANAGEMENT_KEY:+set}"

If the output is set — proceed to Step 2.
If empty — inform the user:
The status line needs ZENMUX_MANAGEMENT_KEY to fetch account data. Create one at https://zenmux.ai/platform/management, then add to your shell profile:
```
export ZENMUX_MANAGEMENT_KEY="sk-mg-v1-..."
```
Without the key, the status line will still show session info (model, git, context remaining) and display a setup hint on Line 2.
The user can proceed without the key — the script degrades gracefully and shows a hint on how to configure it.

Step 2 — Install the status line script

Determine the absolute path to the bundled script. It lives next to this SKILL.md:

SKILL_DIR="$(cd "$(dirname "${BASH_SOURCE[0]:-$0}")" && pwd)"
# Falls back to the skill directory path from the skills install location

Copy it to the Claude Code config directory:

cp "SKILL_SCRIPTS_DIR/zenmux-statusline.sh" ~/.claude/zenmux-statusline.sh
chmod +x ~/.claude/zenmux-statusline.sh

Where SKILL_SCRIPTS_DIR is the scripts/ directory inside this skill. Use the actual resolved path.

If the user already has a ~/.claude/statusline*.sh file, inform them that it will be replaced and confirm before overwriting.

Step 3 — Configure Claude Code settings

Read the user's current settings:

cat ~/.claude/settings.json

Update the statusLine field to point to the new script. Preserve all other settings. The target configuration:

{
  "statusLine": {
    "type": "command",
    "command": "sh ~/.claude/zenmux-statusline.sh",
    "refreshInterval": 120
  }
}

The refreshInterval: 120 re-runs the script every 120 seconds so the ZenMux data refreshes even during idle periods, matching the cache TTL.

Use the Edit tool to update the settings file. Be careful to preserve the existing JSON structure.

Step 4 — Verify the installation

Test the script with mock input to confirm it runs without errors:

echo '{"model":{"id":"test-model"},"workspace":{"current_dir":"'$(pwd)'"},"context_window":{"used_percentage":0},"session_id":"verify-install"}' | sh ~/.claude/zenmux-statusline.sh

If output appears (at least one line), the installation is successful.

Tell the user:

Status line installed. It will appear at the bottom of Claude Code on your next interaction.

What it shows:

Line 1: Model slug, directory, git branch, context used bar, last-call prompt cache read/write

Line 2: ZenMux plan tier, API key type + masked key, 5-hour and 7-day quota usage with color-coded bars, PAYG wallet balance

Colors:

Context used: Green (<70%), yellow (70–89%), red (90%+)

Quota usage: Green (<70%), yellow (70–89%), red (90%+)

Caching: ZenMux API data is cached for 120 seconds to keep the status line fast. Git data is cached for 5 seconds.

To remove it later, delete the statusLine field from ~/.claude/settings.json.

Communication guidelines

Respond in the same language the user writes in (Chinese → Chinese, English → English).
If any step fails, diagnose the error clearly and suggest a fix before moving on.
Do not make changes to ~/.claude/settings.json without showing the user what will change.
