Prompt Engineering & Context Design

Prompt engineering is a writing skill that happens to use code. Clever instructions are the easy part. The real work is structuring system prompts, designing few-shot examples, managing context windows, and building reusable templates that hold up across thousands of runs. The discipline has matured in 2026. It now covers chain-of-thought orchestration, tool-use formatting, and context compression techniques that squeeze every drop of performance from a token budget.
