skill-statusline

skill-statusline

Rich, themeable statusline for Claude Code with accurate context tracking, 5 color themes, 3 layout modes, and zero dependencies. Uses a fast Node.js renderer on Windows (no Git Bash overhead), pure bash on Unix.

Install

npx skill-statusline install

Or install globally:

npm install -g skill-statusline
ccsl install

The installer walks you through choosing a theme and layout. Use --quick to skip the wizard and use defaults.

Cost	Green	Session cost in USD
Context	Adaptive	40-char bar — white <=40%, orange 41-75%, red 76-90%, deep red >90%
Session	Dim	Cumulative tokens across all turns (full layout)
Duration	Dim	Session elapsed time (full layout)
Lines	Dim	+added/-removed (full layout)
Cache	Blue	Write/Read cache token counts (full layout)
Vim	Teal	NORMAL/INSERT mode when vim mode is on (full layout)
Agent	Blue	@agent-name when running with --agent (full layout)

Accurate Context Tracking

v2 computes context percentage from actual token counts (current_usage.input_tokens + cache_creation + cache_read) divided by context_window_size, instead of relying on the pre-calculated used_percentage which can lag behind. This fixes the v1 bug where the bar showed 77% while real usage was 92%.

Compaction warnings appear at configurable thresholds:

• 85%+: Shows remaining percentage (15% left)
• 95%+: Shows COMPACTING warning

Architecture

Two rendering engines — the installer picks the right one for your platform:

• Windows: Node.js renderer (statusline-node.js) — single process, no subprocess spawning, ~30-50ms
• macOS/Linux: Bash engine (core.sh) — pure bash, zero dependencies, <50ms with caching

Git Bash on Windows has ~50-100ms overhead per subprocess spawn (awk, sed, grep, git, date). A bash statusline spawning 10-20 subprocesses = 500-1000ms. The Node.js renderer eliminates this by doing everything in a single process.

~/.claude/
  statusline-command.sh           # Bash entry point (macOS/Linux)
  statusline-node.js              # Node.js renderer (Windows)
  statusline/
    core.sh                       # Bash engine: parse JSON, compute fields, render
    json-parser.sh                # Nested JSON extraction (no jq)
    helpers.sh                    # Utilities + filesystem caching
    themes/{default,nord,...}.sh  # Color palettes
    layouts/{compact,...}.sh      # Render functions
  statusline-config.json          # User preferences

Terminal width is auto-detected — layouts gracefully degrade on narrow terminals.

Requirements

• Node.js >=16 (installer + Windows renderer)
• Git (for GitHub field)
• Bash (macOS/Linux runtime only — not needed on Windows)
• Works on Windows, macOS, Linux
