ThePrimeagen says an hour of prompting ate 56% of a $500 plan

ThePrimeagen bought the $500 weekly plan and says roughly 60 minutes of prompting consumed 56% of his weekly limits. In a follow-up he added that he now sees why people hate Astra, which suggests the burn came from a model he did not pick deliberately. He did not say what he was building.

Pocock's prompt of the day: read my last 10 agent sessions

Matt Pocock posted a /retro prompt that asks the agent to read his last 10 coding sessions and find where agents took too long to locate information or relied on out of date docs. The output is a list of changes to make the repo easier to navigate. He calls navigability an underrated way to save tokens.
