modernize SKILL.md skillA
modernize from bendrucker/claude is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.

Survey a project for ways to adopt newer language and major-dependency features that did not exist when the code was written, replacing boilerplate with modern idioms. Use when the user wants to modernize a codebase, adopt new language features, retire dependencies the stdlib now subsumes, or catch a project up to current framework APIs.
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
# Modernize Find where a project still does things the old way because newer features did not exist when it was written, and propose semantics-preserving swaps. The deliverable is a **ranked survey of candidates** the user picks from. Applying is a separate phase, run only on the candidates they choose. Language-agnostic by design. Detect the stack, never assume it. ## Modernization axes Two axes, plus a third that is easy to miss: - **Language features.** Syntax and stdlib additions that replace boilerplate: pattern matching, comprehensions, `async`/`await` over callbacks, records and dataclasses, native nullability, structured concurrency. - **Major dependencies.** Framework and major-library APIs that supersede older usage, such as a new router, data-fetching primitive, or config format. Frameworks and load-bearing libraries only, not every transitive dependency. - **Stdlib subsumption.** A third-party dependency the language or runtime has since absorbed, like native `fetch`, `structuredClone`, `Array.prototype.flat`, or `std::format`. Retiring a now-redundant dependency is the highest-leverage move, because it deletes code and a dependency at once. ## Three disciplines …

How to install
mdr add bendrucker/claude/modernize@sha256:d4f2dfe67a5998aeThe line at the top of this page pins the label git:20260615.a1b2242, 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.
