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 &&, use rtk:
# Wrong
git add . && git commit -m "msg" && git push
# Correct
rtk git add . && rtk git commit -m "msg" && rtk git push
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)
RTK Commands by Workflow

Token Savings Overview
| Category | Commands | Typical Savings |
|---|---|---|
| Tests | vitest, playwright, cargo test | 90-99% |
| Build | next, tsc, lint, prettier | 70-87% |
| Git | status, log, diff, add, commit | 59-80% |
