Apply Kernighan's Law when reviewing code, discussing code complexity, advising on coding style, or coaching developers on how to write maintainable code. Trigger on phrases like "this clever solution", "I wrote a really elegant piece of code", "look at this one-liner", "why is this code hard to debug?", or any situation involving the trade-off between cleverness and clarity. Also trigger when someone is struggling to debug complex code or asking whether a clever approach is worth the cost.

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

# Kernighan's Law

> "Everyone knows that debugging is twice as hard as writing a program in the first place. So if you're as clever as you can be when you write it, how will you ever debug it?"
> — Brian Kernighan, 1974 (The Elements of Programming Style)

## The core idea

Writing clever code feels good. It demonstrates mastery and intelligence. But if you write code at the absolute limit of your ability to understand, you have no margin left to debug it when something goes wrong — and something will always go wrong.

The smarter move is to write code that is simpler than you're capable of. Leave yourself headroom.

## What "clever" code actually costs

**Time to understand:** Code that is dense, abstract, or uses advanced tricks is hard to read — for you, six months later, and especially for colleagues.

**Debugging difficulty:** When clever code breaks, the same cleverness that makes it compact also makes the failure mode opaque. You have to fully reconstruct the intent before you can find the bug.

**Review friction:** Code reviewers who don't immediately understand code are slower and less thorough. Bugs slip through.

How to install

The exact contents, by fingerprint
mdr add the-artificer-of-ciphers-llc/skills-from-the-artificer/kernighans-law@sha256:1d2e70c19472f99d

The line at the top of this page pins the label git:20260530.3e17152, 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.
