Compresses any dense technical material — a postmortem, RFC, design doc, long Slack/email thread, dashboard dump, or vendor report — into a headline-first executive summary: bottom line up front, the few points that actually matter, and what (if anything) is needed from the reader. Use when the user says "summarize this for my VP/CTO", "TL;DR this", "make this exec- ready", "too long, cut it down", or pastes a wall of technical text. Use this to compress an existing artifact of any shape — use exec-status-update for a structured weekly team status, and board-engineering-summary for an investor-level board section.
