Score Normalization

The algorithm applies normalization to balance positive and negative signals:

Final Score = Base Score (0-100) + Penalties (-75 to 0)
Normalized Score = max(0, min(100, Final Score))

Penalty Capping:

• Total penalties ≤ -20: Applied at full weight
• Total penalties > -20: Gradual dampening begins
• Total penalties > -75: Hard cap at -75 to prevent over-penalization

This prevents a single negative signal from completely dominating the score while maintaining their importance in the algorithm.

Text Analysis Limitations

This skill performs heuristic text-based analysis, not ML prediction.

What This Skill Cannot Detect

Missing Metadata:

• Actual media presence (photos, videos)
• Real video duration or quality
• Actual click-through rates
• True engagement metrics
• Author reputation/follower count
• Tweet timestamps or virality history

Cannot Access:

• Phoenix ML model predictions
• User interaction history
• Network graph relationships
• Real-time engagement signals

What This Skill Infers From

Text-Based Heuristics:

• Language patterns and structure
• Content formatting (threads, lists, etc.)
• Emotional tone and style
• Visual indicators (emojis, markdown)
• Call-to-action strength
• Question vs. statement structure

Scoring Approach:

• Conservative: Unknown elements get baseline scores
• Pattern-Based: Detects language cues (e.g., 📸 for photos, 🧵 for threads)
• Optimization-Focused: Best used for pre-publishing content improvement

Best Use Case

Pre-publishing optimization to maximize engagement potential, not post-hoc analytics or prediction of actual engagement numbers.

Language Handling

Detect input language. Respond in same language. Keep optimized version in original language.
