Few-shot prompting dramatically improves LLM performance by showing examples of previous work instead of describing requirements in natural language. The technique works by providing the LLM with actual code, screenshots, or previous outputs to replicate, eliminating ambiguity. Practical applications include duplicating GitHub Actions scripts across repositories with modifications, creating marketing materials that match existing brand styles, and generating slash commands with consistent structure. Success requires organizing work in accessible folders and committing to version control. The approach becomes more effective over time as you accumulate more examples to reference.
