npx skills add affaan-m/ecc --skill repo-scan
Bootstrap pointer that installs the external repo-scan skill from a pinned, reviewable commit. Use when repo-scan must be installed before running its cross-stack source-code asset audit; this ECC pointer does not perform the audit itself.
npx skills add affaan-m/ecc --skill 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.
Installation completes only the bootstrap. Reload your agent harness, then invoke repo-scan again. This ECC pointer installs the external skill but does not run a scan itself.
| Capability | Description |
|---|---|
| Cross-stack scanning | C/C++, Java/Android, iOS (OC/Swift), Web (TS/JS/Vue) in one pass |
| File classification | Every file tagged as project code, third-party, or build artifact |
| Library detection | 50+ known libraries (FFmpeg, Boost, OpenSSL…) with version extraction |
| Four-level verdicts | Core Asset / Extract & Merge / Rebuild / Deprecate |
| HTML reports | Interactive dark-theme pages with drill-down navigation |
| Monorepo support | Hierarchical scanning with summary + sub-project reports |
| Level | Files Read | Use Case |
|---|---|---|
fast | 1-2 per module | Quick inventory of huge directories |
standard | 2-5 per module | Default audit with full dependency + architecture checks |
deep | 5-10 per module | Adds thread safety, memory management, API consistency |
full | All files | Pre-merge comprehensive review |
On a 50,000-file C++ monorepo:
standard depth for first-time auditsfast for monorepos with 100+ modules to get a quick inventorydeep incrementally on modules flagged for refactoring# Clone first so the pinned commit can be reviewed before installation
