Built a quick, sub-15ms Rust CLI/TUI to pack repos into prompts without burning 40k tokens on lockfiles and junk

A developer created a Rust CLI/TUI tool to efficiently pack code repositories into prompts for large language models (LLMs). The tool aims to prevent "prompt pollution" by excluding unnecessary files like lockfiles (e.g., "Cargo.lock", "package-lock.json"), which can consume over 30,000 tokens without providing useful information. This open-source solution, released under MIT/Apache licenses, processes data in under 15ms, making it faster and more cost-effective for feeding codebases to models like Qwen and DeepSeek R1.
