What this skill does
Prompt Repetition Problem Being Solved LLMs are trained as Causal Language Models, where each token attends only to previous tokens. This leads to: 1. Context-Question Problem: The question is unknown when processing context 2. Options-First MCQ Problem: Cannot fully understand the question context when viewing answer choices 3. Position/Index Problem: Attention weights weaken for specific position information in long lists Prompt repetition enables the second pass to reference the entire first pass, effectively mimicking some benefits of bidirectional attention. --- When to use this skill When using lightweight models: claude-haiku, gemini-flash, gpt-4o-mini, etc. Options-First MCQ: Multiple choice where answer choices appear before the question Context + Question: Searching for specific information in long contexts Index/Position Tasks: Position-based queries in inventories or lists NPC Dialogue: Maintaining consistency for game AI characters Non-Reasoning Tasks: Tasks that do not use Chain-of-Thought --- How It Works Limitations of Causal Attention How Prompt Repetition Solves This In the second repetition, the model reprocesses information across the entire first prompt and strengthens attention weights on key concepts, resulting in improved performance. Note: This does not change the model architecture to bidirectional; it is a prompt engineering technique to mitigate the limitations of causal models. …
