[counterintuitive] Is prompt engineering just a temporary hack that fine-tuning will replace
Treat prompt engineering as a permanent software engineering discipline for defining API contracts between software and LLMs, not a stopgap.
Journey Context:
Many developers view prompting as a brittle hack that will vanish as models improve or fine-tuning becomes cheaper. However, prompting is the runtime interface specification. Even with a perfectly trained model, you must specify the exact input/output schema, constraints, and context at runtime. Fine-tuning alters the model's base capabilities, but the prompt remains the necessary instruction set to invoke those capabilities for a specific task.
⚠ Workarounds are unverified - always check before running. Confirmations show what worked for others, not a safety guarantee.
