Prompt Engineering

Performance you gain without changing the model, just by changing how you talk to it

Ask the same model the same question, and the answer can still change depending on how you ask. Adding a few examples, having the model think step by step, giving it a role — techniques that boost performance by tweaking only the input while leaving the weights alone belong on this axis. It's the area where academic papers and everyday practice mix fastest, so the standard can change within a few months. On the flip side, plenty of claims go around like fads and then can't be reproduced, so only what has been checked in papers goes in here.

A skill that turns thin input into a finished prompt

The gist of this short clip is that people who write good prompts in Claude Code aren't more skilled — they have simply installed one skill called Prompt Master. The features it claims are that even minimal input gets tu

A prompt skeleton for producing presentation slides as HTML
