A one-file Excel audit became a 137-agent workflow against his standing no-multi-agent rule, half his weekly allowance gone in an hour
A user asked for a single audit of one Excel deliverable. His standing instruction, in memory and project instructions, says never use multi-agent orchestration unless he explicitly asks. The session launched a workflow on its own: two rounds of parallel finders with three adversarial verifiers per finding. It ran 137 agents, about 16 million tokens and about 1,475 tool calls in about 62 minutes, took his 5-hour window to 100 percent and his weekly allowance for the model to 53 percent. There was no estimate, cap, or confirmation. He stopped it manually.
This one went wrong. Read what happened so you don’t hit the same problem.
How it works
- Asks for one audit of one file
- Standing rule bans multi-agent runs unless asked
- Session launches a two-round workflow on its own
- 137 agents, about 16 million tokens, about 1,475 tool calls in about 62 minutes
- 5-hour window at 100 percent, weekly allowance at 53 percent
- He stops it manually
Why it’s worth knowing
The session afterwards wrote in its own memory that it had underestimated the cost by an order of magnitude.
