Developer Finds Claude 3 Opus Agents Stuck in Subagent Forking Loop
bdsqlsz · x · 2026-07-23
Developer @bdsqlsz shared observations on the anomalous behavior of the Claude 3 Opus model in agentic mode:
- Infinite Subagent Splitting: The Opus model seemingly uses special system prompts that continuously create more subagents. These subagents fork the prompt and loop to create even more.
- High Context Usage: Subagents default to using forkturns, meaning each subagent takes up a full context fork and constantly compacts the context.
- Optimization: The developer recommends setting forkturns to none or 2 to prevent compute and context waste.
