+description: >-
+  Copy/paste detector for programming source code. Finds duplicated blocks in
+  200+ file formats — JavaScript, TypeScript, Python, Java, C#, C/C++, Go,
+  Rust, PHP, Ruby and more — using token-based detection. Supports
+  configurable thresholds and ignore patterns, git blame integration, and
+  reporters for console, HTML, JSON, Markdown, SARIF and badges. Runs via CLI,
+  in CI pipelines, or as a library; bundled by MegaLinter and Codacy.
