Claude HUD Cubence
A fork of jarrodwatts/claude-hud with Cubence balance and API latency display.
What's New
Adds a Cubence segment to the context line, showing your account balance and API latency:
Context █░░░░░░░░░ 5% │ Cubence $12.34 230ms
With subscription:
Context █░░░░░░░░░ 5% │ Cubence 5h $1.23/$5.00 bal $12.34 230ms
- Reads
ANTHROPIC_AUTH_TOKENandANTHROPIC_BASE_URLfrom~/.claude/settings.json - Calls Cubence API
/v1/user/subscription-infoto fetch balance - 180s file cache to avoid excessive API calls (statusline refreshes every ~300ms)
- API round-trip latency measured during balance fetch
- Graceful degradation: falls back to stale cache on API failure, hides if no token configured
Install
Inside Claude Code, run:
Step 1: Add the marketplace
/plugin marketplace add nangongwentian-fe/claude-hud-cubence
Step 2: Install the plugin
⚠️ Linux users: Click here first
On Linux, /tmp is often a separate filesystem (tmpfs), which causes plugin installation to fail with:
EXDEV: cross-device link not permitted
Fix: Set TMPDIR before installing:
mkdir -p ~/.cache/tmp && TMPDIR=~/.cache/tmp claude
Then run the install command below in that session.
/plugin install claude-hud-cubence
Step 3: Configure the statusline
/claude-hud:setup
⚠️ Windows users: Click here if setup says no JavaScript runtime was found
Install Node.js LTS first:
winget install OpenJS.NodeJS.LTS
Then restart your shell and run /claude-hud:setup again.
Done! Restart Claude Code to load the new statusLine config.
Enable Cubence Balance
After installing, enable the Cubence display in your HUD config:
Edit ~/.claude/plugins/claude-hud-cubence/config.json:
{
"display": {
"showCubenceBalance": true
}
}
Your ~/.claude/settings.json must have the Cubence credentials:
{
"env": {
"ANTHROPIC_AUTH_TOKEN": "your-cubence-api-key",
"ANTHROPIC_BASE_URL": "https://api.cubence.com"
}
}
