Audit a stale, inherited, or messy codebase — deps, bugs, security, tests, CI, docs, UI/UX — then emit a phased, testable modernization plan. Read-only: plans upgrades, never applies them. Not for single-PR review, PRD-to-tasks, or UX-only audits.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Codebase Modernizer For a codebase you are returning to after a long gap, or one that has drifted through many unoptimized changes. It audits every applicable dimension, then converts the findings into a **phased, sprint-sized, testable plan** for 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 | ## Read-only contract This skill **never modifies source code, dependencies, lockfiles, or configuration** — no tracked file's content changes. On a clean tree that is `git diff --stat` empty. On a stale, already-dirty tree, `git status --porcelain` and `git diff` after the run must match a snapshot taken before it (declared artifacts set aside). Beyond the two reports, only two kinds of *new* file may appear, both enumerated in the report's Artifacts section: a **declared delegate artifact** (`CODE_REVIEW.md`, from `code-review` mode `review`) and **probe byproducts** (build dirs such as …

How to install
mdr add luongnv89/skills/codebase-modernizer@sha256:d209f0158d959840The line at the top of this page pins the label v1.4.1, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
