Why this site exists

Tested 160+ popular Claude codes for three months. Most only change how it sounds.

Every “Claude pro tip” thread on the internet is someone's hunch. I got tired of arguing about it, so I built a rig, fresh contexts per trial, a fixed battery of 24 tasks across writing, coding, and analysis, outputs rated blind by three reviewers on decisiveness, accuracy, and token efficiency.

Forty-seven percent of the widely-shared codes showed no significant lift over a plain prompt. The other 53% did, and a handful were genuinely big. The cheat sheet is those 53%, with the failure modes documented for the rest.
