Apply Knuth's Optimization Principle when someone wants to optimize code before establishing it's a bottleneck, is using complex data structures for perceived performance, is making code harder to read "for speed", or is debating whether to optimize something that hasn't been profiled. Trigger on phrases like "I should make this faster", "let's pre-optimize this", "I used X instead of Y for performance", "this might be slow", or any discussion where performance is the motivation for added…
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
# Knuth's Optimization Principle > "Premature optimization is the root of all evil." > — Donald Knuth, 1974 (often attributed; the full quote is more nuanced) ## The core idea Optimizing code before you know it's a bottleneck is one of the most common and costly mistakes in software development. It makes code harder to read, harder to change, and harder to debug — all in service of a performance problem that may not exist, or that may not be in the place you're optimizing. ## The full Knuth quote The complete passage is important and often missed: > "We should forget about small efficiencies, say about 97% of the time: premature optimization is the root of all evil. Yet we should not pass up our opportunities in that critical 3%." The principle is **not** "never optimize." It's: - Don't optimize before you've measured. - Don't optimize the 97% that doesn't matter. - Do optimize the 3% that actually is the bottleneck — carefully and deliberately. ## Why premature optimization is harmful …

How to install
mdr add the-artificer-of-ciphers-llc/skills-from-the-artificer/knuths-optimization-principle@sha256:196aff8f2dd4cc7cThe 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.
