RTK (Rust Token Killer) - Token-Optimized Commands

When running shell commands, always prefix with rtk. This reduces context usage by 60-90% with zero behavior change. If rtk has no filter for a command, it passes through unchanged — so it is always safe to use.

Key Commands

# Git (59-80% savings)
rtk git status          rtk git diff            rtk git log

# Files & Search (60-75% savings)
rtk ls <path>           rtk read <file>         rtk grep <pattern>
rtk find <pattern>      rtk diff <file>

# Build (80-90% savings) — shows errors only
rtk ./gradlew build     rtk ./gradlew compileJava

# Test (90-99% savings) — shows failures only
rtk ./gradlew test

# Analysis (70-90% savings)
rtk err <cmd>           rtk log <file>          rtk json <file>
rtk summary <cmd>       rtk deps                rtk env

# GitHub (26-87% savings)
rtk gh pr view <n>      rtk gh run list         rtk gh issue list

# Infrastructure (85% savings)
rtk docker ps           rtk kubectl get         rtk docker logs <c>

Rules

In command chains, prefix each segment: rtk git add . && rtk git commit -m "msg"
For debugging, use raw command without rtk prefix
rtk proxy <cmd> runs command without filtering but tracks usage
