Codebase Modernizer
For a codebase you are returning to after a long gap, or one that has drifted through many unoptimized changes. It audits the whole repo across every applicable dimension, then converts the findings into a phased, sprint-sized, testable plan for producing a better, up-to-date version.
Produces exactly two files in the target repo root:
| File | Contents |
|---|---|
MODERNIZATION_REPORT.md |
Baseline evidence + every finding, severity-ranked, each citing path:line |
MODERNIZATION_PLAN.md |
Phases → sprints → tasks → milestones, every task closing named findings |
