code-reduction SKILL.md skillB
code-reduction from philoserf/claude-code-config is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add philoserf/claude-code-config/code-reduction@git:20260913.f2c2f15Pins git:20260913.f2c2f15 in mdr.lock. Pin the fingerprint instead.

Reviews a codebase for what to delete, inline, and flatten — abstractions that don't earn their keep, ceremonial types, obscuring indirection, tests of language features. Use when code has accreted structure and needs shrinking. Writes findings to `.issues/`; recommends changes but does not apply them.
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
Review this codebase and advise on refactoring to reduce, simplify, remove, and reorganize. The goal is less code and fewer concepts, not tidier code. Scope the review to `$ARGUMENTS` if provided, otherwise review the whole project. Examples: `src/api/`, `the test suite`, `lib/parsers/`. Skip vendored dependencies, build output, generated code, and lockfiles (`node_modules/`, `dist/`, `vendor/`, `*.min.js`, `go.sum`). ## First, establish the license to delete This skill assumes **sole-owner code with no backward-compatibility constraints**. That assumption is what makes aggressive deletion the right call, so check it before leaning on it: look for a published package name, semver tags, a CHANGELOG, a documented public API, or `deprecated` markers that imply someone downstream. If you find signs of external consumers, say so explicitly and mark which recommendations the constraint blocks — don't silently soften the whole review. ## What to look for …

How to install
mdr add philoserf/claude-code-config/code-reduction@sha256:337c66ed337a5c05The line at the top of this page pins the label git:20260913.f2c2f15, 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.
