prompt-engineering

The Principle of Parsimony in Context Engineering is a design rule for LLM prompts and context: formulate instructions and select artifacts in the minimum sufficient number of tokens that ensure unambiguous task interpretation, reserving the remaining token budget for the most valuable elements.

I use Claude and Cursor in development every day. Over time I noticed that I don't have one fixed workflow. I choose the approach depending on the task. Three real examples show when prompt engineering is enough and when you need context engineering.
