repo-scan

Every ecosystem has its own dependency manager, but no tool looks across C++, Android, iOS, and Web to tell you: how much code is actually yours, what's third-party, and what's dead weight. Review the source before installing any agent skill. On a 50,000-file C++ monorepo: - Taking over a large legacy codebase and need a structural overview - Before major refactoring — identify what's core, what's duplicate, what's dead - Auditing third-party dependencies embedded directly in source (not declared in package managers) - Preparing architecture decision records for monorepo reorganization - Classify the repo surface : enumerate files, then tag each as project code, embedded third-party code, or build artifact. - Detect embedded libraries : inspect directory names, headers, license files, and version markers to identify bundled dependencies and likely versions. - Score each module : group files by module or subsystem, then assign one of the four verdicts based on ownership, duplication, and maintenance cost. - Highlight structural risks : call out dead-weight artifacts, duplicated wrappers, outdated vendored code, and modules that should be extracted, rebuilt, or deprecated. - Produce the report : return a concise summary plus the interactive HTML output with per-module drill-down so the audit can be reviewed asynchronously. - Found FFmpeg 2.x (2015 vintage) still in production -...
