+# Intent vs Prescriptive Spectrum
+
+**Principle:** Workflows lean toward **intent** (goals) not **prescription** (exact wording). The more intent-based, the more adaptive and creative the LLM can be.
+
+---
+
+## When to Use Each
+
+### Intent-Based (Default)
+**Use for:** Most workflows - creative, exploratory, collaborative
+**Step instruction:** "Help the user understand X using multi-turn conversation. Probe to get good answers. Ask 1-2 questions at a time, not a laundry list."
+**LLM figures out:** Exact wording, question order, how to respond
+
+### Prescriptive (Exception)
+**Use for:** Compliance, safety, legal, medical, regulated industries
+**Step instruction:** "Say exactly: 'Do you currently experience fever, cough, or fatigue?' Wait for response. Then ask exactly: 'When did symptoms begin?'"
+**LLM follows:** Exact script, specific order, no deviation
+
+---
+
+## Examples
+
+### Intent-Based (Good for most)
+```
+"Guide the user through discovering their ideal nutrition plan.
+Use multi-turn conversation. Ask 1-2 questions at a time.
+Think about their responses before asking follow-ups.
+Probe to understand preferences, restrictions, goals."
+```
+
+### Prescriptive (Only when required)
+```
+"Medical intake - ask exactly:
+1. 'Do you have any of these symptoms: fever, cough, fatigue?'
+2. 'When did symptoms begin?'
+3. 'Have you traveled recently in the last 14 days?'
+Follow sequence precisely. Do not deviate."
+```
+
+---
+
+## Step Writing Tips
+
+- **Default to intent** - give goals, not scripts
+- **Use "think"** - "Think about their response before..."
+- **Multi-turn** - "Use conversation, not interrogation"
+- **Progressive** - "Ask 1-2 questions at a time"
+- **Probe** - "Ask follow-ups to understand deeper"
+
+Only use prescriptive when compliance/regulation requires it.
