Reduce a repository's maintenance surface across the whole codebase with KISS, DRY, and YAGNI while preserving required behavior. Use when asked to simplify, shrink, deduplicate, remove dead code, or refactor for maintainability, and proactively when the agent identifies clear, material simplification opportunities.

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

# Simplify Codebase

Reduce the repository to the smallest clear implementation that satisfies current requirements. Minimize maintenance surface, not line count.

## Rules

- Preserve required behavior, outputs, repository standards, and identified external contracts. No in-repository caller is not enough to remove a public API, CLI/configuration contract, data format, migration requirement, or supported platform.
- **KISS:** Prefer readable, explicit control and data flow, standard primitives, and the fewest useful layers over clever or dense code.
- **DRY:** Consolidate duplicated knowledge or equivalent logic only when one representation is clearer; do not merge distinct concerns or remove useful abstractions merely to reduce repetition.
- **YAGNI:** Remove functionality, flexibility, compatibility, configuration, or infrastructure without a current requirement.
- Simplify in this order: delete unused material, reuse existing code, inline needless indirection, consolidate equivalent paths, then abstract only stable repeated knowledge.

How to install

The exact contents, by fingerprint
mdr add dceoy/ai-coding-agent-skills/simplify-codebase@sha256:997f6e28562a11e0

The line at the top of this page pins the label git:20260825.68ee2ed, 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.
