It displays the subscription plan (or API/provider), current Anthropic model, context window usage, and 5-hour/7-day quota usage as ANSI-colored progress bars. Written in Go with no external dependencies (stdlib only).

[!NOTE]

The 5-hour and 7-day quota bars require a Claude Code subscription (Pro, Max, or Team). They are not available for free tier, Enterprise or API key users. The bars may also disappear silently if the usage API is temporarily unavailable or rate limited — use -debug to diagnose.

🥵	Extended context (>200k tokens) — model quality may degrade
🔥▂ 🔥▄▂ 🔥▆▄▂	Anthropic service disruption (minor / major / critical)
↑	New claudeline update available

Installation

Via Claude Code plugin

1. Inside Claude Code, add the plugin marketplace and install:

/plugin marketplace add fredrikaverpil/claudeline
/plugin install claudeline@claudeline

2. Run /claudeline:setup inside Claude Code — this downloads the Go binary and configures your statusline
3. Restart Claude Code

Manual

1. Download the latest binary from GitHub releases, or use go install github.com/fredrikaverpil/claudeline@latest.
2. Add the statusline to ~/.claude/settings.json:

{
  "statusLine": {
    "type": "command",
    "command": "/path/to/claudeline",
  },

Architecture

Single-binary design with main.go orchestrating internal/ packages.

Data flow: stdin JSON → parse input + read credentials → fetch usage (cached) + fetch status (cached) + check update (cached) → render ANSI output → stdout
