What it does

This skill installs rtk, a small command-line proxy that shortens the output of common developer commands such as git, cargo, pytest, docker and kubectl before it reaches the AI model. The skill claims this saves 60-90% of tokens. It sets this up inside NanoClaw agent containers by mounting the rtk program and adding a Claude Code PreToolUse hook so every Bash call is filtered automatically.

Great for

  • Developers running NanoClaw agent groups who make many shell calls to git, test runners or container tools
  • Operators who want to lower token costs for long coding sessions inside containers

Skip it if

  • Setups that do not use NanoClaw agent containers, since the steps depend on its ncl command and data folder layout
  • Users who need full, unfiltered command output for debugging, because rtk compresses what the agent sees and may hide details

Try asking

  • “Install rtk into my NanoClaw agent group so git and pytest output uses fewer tokens”
  • “Set up the rtk PreToolUse hook for group ag-1776342942165-ptgddd”
  • “Check how many tokens rtk has saved so far”

    Ask for the task

    No special command needed — the agent reads the skill's description and loads it when your request matches. Try one of the prompts above.

Get better results

  • Review the rtk install script at the URL in Step 1 before piping it to sh, since it runs with your user's permissions
  • Run the verify steps after restarting the group to confirm the binary is executable inside the container
  • Use REMOVE.md to undo the changes if rtk filtering causes missing output
