+# Prompt Optimization Rules
+
+## Core Rules
+
+### Rule 1: Specificity Over Generality
+
+| Instead of | Use |
+|------------|-----|
+| "Make it better" | "Reduce load time to under 2 seconds" |
+| "Add some validation" | "Validate email format and require 8+ char password" |
+| "Handle errors" | "Show toast notification on API failure, log to console" |
+
+### Rule 2: Include Context
+
+Every good prompt includes:
+- **What**: The action/feature/fix needed
+- **Where**: Location in codebase or UI
+- **Why**: Purpose or problem being solved
+- **Constraints**: Technical limits, compatibility, standards
+
+### Rule 3: Define Success
+
+Specify how to know when the task is done:
+- Acceptance criteria
+- Test cases to pass
+- Behavior to verify
+
+### Rule 4: Scope Boundaries
+
+Explicitly state:
+- What IS in scope
+- What is NOT in scope
+- What MIGHT be in scope (user's call)
+
+## Anti-Patterns to Detect
+
+### Vague Requests
+
+Triggers: "improve", "fix", "update", "change", "better", "faster", "cleaner"
+
+Response: Ask for specific metrics or outcomes
+
+### Scope Creep Signals
+
+Triggers: "while you're at it", "also", "might as well", "and another thing"
+
+Response: Acknowledge, then isolate: "I'll note that for after the main task"
+
+### Assumption Gaps
+
+Triggers: References to "the" thing (which thing?), "it" (what's it?), "there" (where?)
+
+Response: Echo back specific understanding
+
+### Conflicting Requirements
+
+Triggers: "Simple but comprehensive", "Fast but thorough", "Minimal but complete"
+
+Response: Prioritize: "Which matters more: simplicity or completeness?"
+
+## Question Templates
+
+### For Unclear Purpose
+
+```
+**What problem does this solve?**
+1. [Specific problem A]
+2. [Specific problem B]
+3. Combination
+4. Different problem: ____
+```
+
+### For Missing Scope
+
+```
+**What should this include?**
+- [ ] Feature A
+- [ ] Feature B
+- [ ] Feature C
+- [ ] Other: ____
+```
+
+### For Ambiguous Behavior
+
+```
+**When [trigger event], what should happen?**
+1. [Behavior option A]
+2. [Behavior option B]
+3. Nothing (ignore)
+4. Depends on: ____
+```
+
+### For Technical Decisions
+
+```
+**Implementation approach:**
+1. [Approach A] - pros: X, cons: Y
+2. [Approach B] - pros: X, cons: Y
+3. Let me decide based on codebase
+4. Need more info about: ____
+```
+
+## Optimization Checklist
+
+Before proceeding with any task, verify:
+
+- [ ] **Specific outcome** - Can measure success
+- [ ] **Clear location** - Know where changes go
+- [ ] **Defined scope** - Know what's in/out
+- [ ] **Error handling** - Know what happens on failure
+- [ ] **Edge cases** - Major scenarios covered
+- [ ] **Dependencies** - Know what this affects/relies on
+
+## ND-Friendly Adaptations
+
+### Reduce Cognitive Load
+- Maximum 4 options per question
+- Always include "Other" escape hatch
+- Provide examples, not just descriptions
+
+### Support Working Memory
+- Summarize frequently
+- Reference earlier decisions explicitly
+- Don't assume user remembers context
+
+### Allow Processing Time
+- Don't rapid-fire questions
+- Validate answers before moving on
+- Offer to revisit/change earlier answers
+
+### Manage Overwhelm
+- Offer to break into smaller sessions
+- Prioritize must-haves vs nice-to-haves
+- Provide "good enough for now" options
