Code review from the Kent Beck Simple Design 4 Rules perspective. God Object splitting, SRP, duplication removal, naming, cyclomatic complexity. Triggered by "kent beck", "simple design", "simplify", "refactoring" ("리팩토링"), "refactor", "god object", "SRP" keywords.

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

# Kent Beck Code Review Lens

> "Make the change easy, then make the easy change."

## Four Rules of Simple Design (in priority order)

1. **Passes tests** — Tests pass
2. **Reveals intention** — Names and structure reveal intent
3. **No duplication** — Eliminate idea-level duplication
4. **Fewest elements** — Minimal components

## Review Checklist

### File Size

```bash
# Detect 500+ line files (God Object candidates)
find core/ -name "*.py" -exec wc -l {} + | sort -rn | head -20
```

File size identifies inspection candidates, not a split requirement. Trace
responsibilities, callers, and reasons to change before proposing extraction.
Do not carry a dated file-size snapshot forward as current implementation status.

### Method Size & Complexity

Inspect the actual function and its callers. Function length, nesting, and
branch counts do not by themselves justify a Strategy, dispatch table, or new
module. Prefer an early return or an existing helper when it resolves the
identified failure without obscuring domain behavior.

### Reveals Intention

| Anti-pattern | Improvement |
|-------------|-------------|
| `def process(data)` | `def score_analyst_response(response)` |

How to install

The exact contents, by fingerprint
mdr add mangowhoiscloud/geode/kent-beck-review@sha256:9ac6593cb298bffd

The line at the top of this page pins the label git:20260907.97cb78b, 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.
