Adds .claude/statusline.sh (reads context_window.used_percentage + context_window_size straight from the statusLine JSON; green<70/yellow/red bar) and wires it via .claude/settings.json statusLine. Committed in-repo so it follows boma to any clone, matching how .claude/ already tracks hooks + plugins. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>

# Claude Code statusLine — shows working dir, model, and context-window usage.
|
||
# Wired via .claude/settings.json (statusLine.command). Receives the statusLine
|
||
# JSON on stdin; first stdout line is rendered (ANSI colour supported).
|
||
#
|
||
# Context usage comes straight from the input JSON — no transcript parsing:
|
||
# .context_window.used_percentage pre-calculated % of the window in use (input side)
|
||
# .context_window.context_window_size window size in tokens (1000000 for the 1M models)
|
