1Rtk OptimizerRTK Optimizer is an agent skill for solo and indie builders who burn context windows on noisy terminal output during Claude Code, Cursor, or similar workflows. When you ask the agent to run git history, diffs, test suites, or large file reads, the skill recognizes those patterns and recommends wrapping them with RTK so summaries replace wall-of-text stdout. That matters because long agent sessions—debugging a failing pytest run, scanning a cargo clippy report, or reviewing a PR with gh—otherwise eat tokens you need for patches and reasoning. The flow is lightweight: detect the command, propose the RTK variant, execute on confirm, optionally tally savings. It is not a test framework or Git replacement; it is a token-efficiency layer on commands you already run while building and shipping.1installs
