RTK Integration

RTK filters and compresses shell command outputs before they reach the LLM context window. Works with any agent/model (Claude, MiniMax, GPT, Gemini, OpenClaw, etc.) — model-agnostic.

Setup

1. Install RTK (auto — run on skill install)

When this skill is installed, immediately run the setup script to install RTK if not already present:

bash skills/rtk-integration/scripts/rtk-setup.sh

The script handles installation automatically (Linux/macOS), adds RTK to PATH, and verifies the install.

Manual install if needed:

# Linux/macOS
curl -fsSL https://raw.githubusercontent.com/rtk-ai/rtk/refs/heads/master/install.sh | sh
echo 'export PATH="$HOME/.local/bin:$PATH"' >> ~/.bashrc && source ~/.bashrc

# macOS Homebrew
brew install rtk

# Verify
rtk --version && rtk gain

2. Initialize hooks (optional, for Claude Code / OpenCode auto-rewriting)

rtk init --global          # Claude Code hook
rtk init --global --opencode  # OpenCode hook

> ⚠️ For OpenClaw agents: hooks don't auto-apply. Use rtk explicitly (see below).

3. Check token savings

Core Rule: Always Use RTK Prefixes

When executing shell commands, always prefer the RTK version over the raw command. RTK adds <10ms overhead and reduces output by 60–90%.

See the full command reference: references/commands.md

Quick reference (most common)

# Files
rtk ls .
rtk read <file>
rtk grep "<pattern>" .
rtk find "*.ts" .
rtk diff file1 file2

# Git (most impactful — use on EVERY git operation)
rtk git status
rtk git diff
rtk git log -n 10
rtk git add .          # outputs just "ok"
rtk git commit -m "msg"  # outputs "ok <hash>"
rtk git push           # outputs "ok main"
rtk git pull

# Tests — show failures only (-90%)
rtk test npm test
rtk test npx jest
rtk vitest run
rtk playwright test
rtk pytest
rtk go test
rtk cargo test

# Build & lint
rtk tsc
rtk next build
rtk lint
rtk lint biome
rtk cargo build
rtk cargo clippy
rtk ruff check .

# Docker
rtk docker ps
rtk docker logs <container>

# Package managers
rtk pnpm install
rtk npm install
rtk yarn install

When NOT to use RTK

• Interactive commands (ssh, vim, htop) — use directly
• Already-compressed output (jq-piped JSON, single-line results)
• When you need the full raw output for debugging
