RTK (Rust Token Killer) - Token-Optimized Commands

Usage: Token-optimized CLI proxy (60-90% savings on dev operations)

Golden Rule

Always prefix commands with rtk. If RTK has a dedicated filter, it uses it. If not, it passes through unchanged. This means RTK is always safe to use.

RTK calls binaries directly — shell aliases are bypassed. No command prefix needed. Use command only for alias-prone commands RTK doesn't cover (cd, cp, mv, rm).

Important: Even in command chains with &&, prefix each command with rtk.

Meta Commands (always use rtk directly)

rtk gain              # Show token savings analytics
rtk gain --history    # Show command usage history with savings
rtk discover          # Analyze Claude Code history for missed opportunities
rtk proxy <cmd>       # Execute raw command without filtering (for debugging)
rtk init              # Add RTK instructions to CLAUDE.md
rtk init --global     # Add RTK to ~/.claude/CLAUDE.md

Installation Verification

rtk --version         # Should show: rtk X.Y.Z
rtk gain              # Should work (not "command not found")
which rtk             # Verify correct binary

Name collision: If rtk gain fails, you may have reachingforthejack/rtk (Rust Type Kit) installed instead.

Hook-Based Usage

All other commands are automatically rewritten by the Claude Code hook. Example: git status → rtk git status (transparent, 0 tokens overhead)
