- The poster says their first deep-research run with Claude Opus 5 consumed both a fresh 5-hour usage window and the remaining $40 of credit in about 10 minutes.
- The reason: the workflow spawned 106 research sub-agents.
- They found it hilarious rather than upsetting, and concluded they need to add a sub-agent limit to Claude-based workflows.
- The takeaway is practical: agent systems need hard constraints in code, not just prompts.
