Claude Epic Status Line

A feature-rich status line for Claude Code that displays model info, context usage, git status, rate limits, session cost, and more — quiet when everything is healthy, loud exactly where something needs attention. Zero-config by default, deeply customizable when you want it (thresholds, palette, glyph sets, per-segment toggles).

The status line itself

Features

Segment	Description
Model	Short model name (e.g., Opus 4.6 instead of Claude Opus 4.6)
Context	Usage percentage + token counts (e.g., 12% (42k/200k)) with color coding
Auto-compact warning	Steady bold ⚠ when context usage >= 80%
Directory	Truncated to last 2 path components
Git branch	Branch name with detailed status: staged (S:2), unstaged (U:1), untracked (A:3)
Git ahead/behind	⇡2⇣1 arrows showing commits ahead/behind upstream
Worktree	⎇wt indicator when running inside a git worktree
Session cost	$X.XX with configurable warn/critical thresholds and currency
Session duration	5m, 1h30m, etc.
Lines changed	+156/-23 cumulative lines added/removed
Per-turn cost	48k/turn — what the next message costs before you type (at the current model's cache-read rate), and 88t turns so far
Cold prompt cache	486k next turn (cache cold) — once the prompt cache has expired, the next message re-writes the whole context
Effort level	● high, ◑ medium, ◔ low (from the session itself)
Badges	Subagent name, fast mode, thinking, vim, non-default output style, ⚠200k+
Rate limits	█░ progress bars for 5-hour, 7-day, per-model, and extra usage with reset times
Pace projection	⇢ 94% — where the 5-hour / 7-day window lands at the current burn rate
Context hint	One line naming the right command: /compact for a full window, /clear for an expensive one

Color coding

One escalation scale drives every percentage-based segment (context, rate bars) — quiet when healthy, then:

• Yellow — ≥ 70% (CESL_WARN)
• Orange — ≥ 80% (CESL_HIGH); context also gains a steady bold ⚠
• Red — ≥ 90% (CESL_CRIT)

Session cost uses its own CESL_COST_WARN/CESL_COST_CRIT thresholds. The per-turn cost uses absolute token thresholds (CESL_CTX_WARN/CESL_CTX_HIGH) because a percentage of a 1M window says nothing about what a message costs — 486k reads as a comfortable 49% full while re-sending 48k tokens every turn at a 10% cache-read rate (24k on Opus 5.5). The model name is colored by model family (Opus, Sonnet, Haiku, Fable).

NO_COLOR and TERM=dumb are honored; CESL_COLOR=0/1 overrides the detection either way.

Requirements

• jq — JSON parsing
• curl — fetching rate limit data from the Anthropic API
• git — branch and worktree detection

Installation

Quick install

git clone https://github.com/dsebastien/claude-epic-status-line.git
cd claude-epic-status-line
bash install.sh

Manual install

1. Copy statusline.sh to ~/.claude/statusline-command.sh
2. Add this to your ~/.claude/settings.json:

{
  "statusLine": {
    "type": "command",
    "command": "bash '/home/YOUR_USER/.claude/statusline-command.sh'"
  }
}

3. Restart Claude Code.

Uninstall

bash uninstall.sh

Or manually remove the statusLine key from ~/.claude/settings.json and delete ~/.claude/statusline-command.sh.

Configuration

Everything is optional — with zero config the status line renders its default design. Settings layer as: script defaults < ~/.config/claude-epic-status-line/config.sh < CESL_* environment variables (environment wins).
