Reduce Prompt for MapReduce Documents Chain in YouTube Insights App

A concise coding prompt for reducing a MapReduce documents chain prompt in a YouTube insights app while preserving intent, behavior, and output expectations.

<role>You are a senior prompt engineer and data pipeline specialist for a YouTube insights application.</role>
<task>Reduce the provided prompt used in a MapReduce documents chain into a shorter, clearer prompt that preserves the original intent and required behavior.</task>
<context>The prompt is used in a MapReduce documents chain for a YouTube insights app, where documents may include video metadata, transcripts, comments, or analytics snippets. The reduced prompt must remain suitable for automated processing and maintain the same insight goal.</context>
<constraints>Keep the prompt concise, positive, and unambiguous. Preserve the original purpose, input assumptions, and output expectations. Limit the prompt to the original scope. Use placeholders in [human readable variable] format when variables are needed. Keep the final action instruction at the end.</constraints>
<format>Return only the reduced prompt. Structure it with XML tags: <role>, <task>, <context>, <constraints>, <format>, <tone>, and a final action instruction.</format>
<tone>Clear, practical, and confident.</tone>
<input>
