You often read that prompt engineering is dead, killed by models that ‘understand everything.’ The reality on the ground is the opposite: as use cases grow more complex (agents, RAG, multi-turn), the prompt becomes code again<\/strong>. It gets versioned, tested, optimized.<\/p>

Three Rules Before Techniques<\/h2>
  1. 1

    Evaluate Before Optimizing<\/p>

    Without an evaluation dataset (10-50 examples with expected output), you’re flying blind. It’s the only way to know if a change actually improves things.<\/p><\/li>

  2. 2

    Small Before Large<\/p>

    Break it down. A prompt that does 4 things badly beats 4 prompts that do 1 thing well. Chaining almost always beats complexification.<\/p><\/li>

  3. 3

    Measure the Right Metric<\/p>

    Accuracy, latency, cost, robustness to hostile inputs: decide what matters before optimizing. The best technique changes by objective.<\/p><\/li><\/ol>

    The 10 Techniques in Detail<\/h2>

    Structured Chain-of-Thought<\/h3>

    Explicitly ask to ‘break down into numbered steps before answering.’ On 2026 models without reasoning mode, it’s still a net reliability gain.<\/p>

    Don't answer right away. (1) List hypotheses. (2) Evaluate each. (3) Compare. (4) Conclude.<\/code><\/pre>\n","protected":false},"excerpt":{"rendered":"
