shell

This skill should be used when running any shell command that has an RTK equivalent — including "git status", "ls", "grep", "find", "cat/head/tail", "pnpm test", "cargo build", "curl", "gh", "docker", "kubectl", "vitest", "pytest", "tsc", "eslint", and any other CLI operation where token savings apply. Also use when the user asks about "rtk gain", "token savings", "rtk discover", or "why use rtk".
