Rtk Optimizer

florianbruniaux/claude-code-ultimate-guide

When you run git log or cargo test in Claude, you're burning thousands of tokens on verbose output you don't need. This skill wraps those commands with RTK, a Rust tool that condenses CLI output while keeping the signal. Think 92% reduction on git log, 90% on pytest. It detects high verbosity commands and suggests the RTK wrapper automatically. The tool itself is young but actively maintained (30 releases in 23 days), so expect some churn. Best for git workflows, test runs, and build output where you're hitting token limits. Skip it for quick one liners under 100 characters.
