Agent burns through 5x Max plan's 5-hour limit in 17 minutes by launching 30 parallel researchers

User teortaxesTex reports Fable Ultracode (high) burned through the 5x Max plan's 5-hour limit in about 17 minutes—14% of the weekly quota, 1% every 73 seconds. Its first and only message explained why: "I'm launching 30 parallel researchers plus a completeness critic." The user had merely asked it to survey the state of the art in memory systems, with API-cost equivalent in the tens of thousands of USD. A cautionary tale about unchecked parallel subagents on subscription plans.
