Features

• Per-prompt metrics -- duration and cost reflect the last prompt cycle, not the full session
• Token breakdown -- input, output, cache write, cache read with cache hit rate
• Cost estimation -- per-prompt and session totals based on published Anthropic pricing
• Context window -- current fill percentage and how much was added in the last prompt
• Rate limits -- 5-hour and weekly utilization with reset countdowns (requires Claude login)
• Enable/disable -- toggle on and off without modifying settings
• Zero dependencies -- pure Node.js, reads Claude Code's own transcript data

• Node.js 18+
• Claude Code CLI (authenticated via claude login)
