Prompt & Context Engineering

In a long-running chat, the assistant starts ignoring formatting instructions given at the very start of the conversation. What's this, and what actually fixes it?

Show answer and explanation

Answer: B — Context drift — reinforce or compact so early instructions stay live

Losing hold of early instructions over a long session is drift, not bloat (bloat is about wasted tokens/cost, not forgotten instructions). Compaction or reinforcement keeps the instruction live; temperature doesn't address memory of instructions at all.
