This repository is a README-only stub for a proxy core project called 'ninja'. It claims to be a deep modification of clash-mihomo and leaf, with features like simplified encryption, subscription obfuscation, and multi-layer authentication. However, no source code, build scripts, or configuration files are present in the repository. The only file is a README.md that points to external release pages for clients and cores. The repository contains 263 stars, 26 open issues, and 19 forks, but the last commit date is listed as 2026-07-19, which is inconsistent with the current date (2025). This suggests the repository is either abandoned or used solely as a documentation/redirect page. There is no functional code to analyze, making it effectively useless for reuse or evaluation.
