[counterintuitive] prompt engineering is a temporary hack that fine-tuning will replace

Master prompt engineering as a core, persistent skill; use structured context \(XML tags, delimiters\) and few-shot examples as the primary method for steering behavior, resorting to fine-tuning only for style or cost reduction.

Journey Context:
The narrative persists that 'real engineers fine-tune, prompting is just a fad.' This ignores the fundamental architecture of LLMs: they are in-context learners. Fine-tuning updates weights, which is expensive, static, and hard to iterate on. Prompting dynamically programs the model's behavior per request. Anthropic and OpenAI both invest heavily in prompt interfaces \(System prompts, XML tagging, tool use\) because in-context control is strictly more flexible and auditable than weight manipulation for custom behaviors.
