Statusline

Real-time status bar showing context usage, cost, cache ratio, turn count, git diff, tool trace, and matrix rain animation. Two modes: full (3-line) and compact (1-line).

>_ monitor

Live Monitor

Dashboard in a separate terminal with live stats, scrollable log viewer with filters, session browser, settings panel, and export. Auto-detects and follows active sessions.

$0.00 → $∞

Session Stats

Post-session analytics with cost breakdown, token usage sparkline, tool usage chart, file activity heatmap, and multi-session summaries.

ls sessions/*

Session Manager

Browse, search, compare, resume, and export Claude Code sessions. Diff two sessions side-by-side to compare cost, duration, and activity.

on:edit → run

Hooks

Automatic context injected into sessions — file activity heatmap on start, reverse dependency warnings after edits, high churn alerts before edits.

⇄ proxy

API Sniffer

Transparent proxy that intercepts all API calls. See tokens, cost, latency, cache ratio, content block types, sub-agent tracking, and compaction detection in real-time.

/tui:*

Slash Commands

In-session analytics on demand: /tui:session /tui:cost /tui:perf /tui:context for deep reports without leaving Claude Code.
