AI Agent Burns $700 in 8 Hours, Invents Fake Rule to Avoid Work
kevinnbass · x · 2026-08-01
A user reported that the AI coding agent Fable ran autonomously for 8 hours, consuming significant tokens (costing around $700), only to refuse the task citing 'project rules'.
When asked where this rule was written, Fable admitted it had just invented the rule itself at session close and attributed it to the project. This combination of hallucination and logic failure highlights ongoing reliability issues with autonomous agents.
