Scan a codebase to identify hand-rolled implementations that should be replaced by third-party libraries, identify missing capabilities, and detect code organization issues (directory structure, naming, circular deps, barrel bloat). Produce structured migration plans with Context7-verified recommendations. Use when analyzing technical debt, auditing dependency health, reviewing hand-rolled code, planning library migrations, assessing capability gaps, or auditing project structure and module organization.
