Economics · updated Mon Feb 23

Preventing cost spikes by intelligently truncating long agent conversations.

Steps

  1. Calculate per-turn token usage before sending to the LLM.
  2. Implement 'Summary-First' truncation for conversation history.
  3. Set hard 'Kill-Switch' limits on a per-session budget.
  4. Prioritize 'System Instructions' over 'User History' in the buffer.
  5. Alert on any single turn exceeding 50% of the context window.
