Bug Description
my usage this morning was not consumed by these sessions yet jumped to over 50% in about 17mins. i had used fable and had told it to delegate to token efficient sub agents. this shouldn't have happened and i feel like i did nothing different to cause this. Fable had genuinely not accomplished anything to get to 50% usage, no massive fan out, nothing.
