Applies KISS, YAGNI, and SOLID principles for clean code with reduced complexity. Use when refactoring or reviewing code for over-engineering.
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 Quality Principles
Guidance on KISS, YAGNI, and SOLID principles with language-specific examples.
## When To Use
- Improving code readability and maintainability
- Applying SOLID, KISS, YAGNI principles during refactoring
## When NOT To Use
- Throwaway scripts or one-time data migrations
- Performance-critical code where readability trades are justified
## KISS (Keep It Simple, Stupid)
**Principle**: Avoid unnecessary complexity. Prefer obvious solutions over clever ones.
### Guidelines
| Prefer | Avoid |
|--------|-------|
| Simple conditionals | Complex regex for simple checks |
| Explicit code | Magic numbers/strings |
| Standard patterns | Clever shortcuts |
| Direct solutions | Over-abstracted layers |
### Python Example
```python
# Bad: Overly clever one-liner
users = [u for u in (db.get(id) for id in ids) if u and u.active and not u.banned]
# Good: Clear and readable
users = []
for user_id in ids:
user = db.get(user_id)
if user and user.active and not user.banned:
users.append(user)
```
### Rust Example
```rust
// Bad: Unnecessary complexity
fn process(data: &[u8]) -> Result<Vec<u8>, Box<dyn std::error::Error>> {
data.iter()

How to install
mdr add athola/claude-night-market/code-quality-principles@sha256:6d5dc3c4be68fc11The line at the top of this page pins the label git:20260902.d04952c, 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.
