Use when the user asks to simplify, clean, or refine code. Not for new abstractions or whole-codebase refactors.

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

# Code simplification

Two modes share one authority: reversible local edits to a named target, no new public surface, behavior preserved. Measured mode proves reduction with the test suite; clarity mode proves preservation by reasoning over the recorded behavior contract.

## Contract

| Field | Bound contract |
|---|---|
| Trigger | User asks to simplify, clean, refactor, or improve the readability of code, or review flags bloat beyond the current diff. |
| Authority | Reversible local: writes only the named target (may refactor, extract, inline, and collapse conditionals; may not add new public surface or edit files outside the target); rollback is version control or undo. No remote mutation. |
| Side effect | Refactoring edits to the named target only; no new public surface. |
| Done | Mode-specific done predicate holds (see each mode); behavior is preserved by tests (measured) or by recorded-contract reasoning (clarity). |

## Inputs

- Target (required): the file, module, function, or range to simplify. Named by the user.
- Test command (required for measured mode): the command that runs the test suite proving behavior preservation.

How to install

The exact contents, by fingerprint

mdr add outlinedriven/outline-driven-development/code-simplification@sha256:b7d8f7fa8bf6fcc7

The line at the top of this page pins the label git:20260905.1f63894, 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.
