Short-Term Memory (Conversation)

In-session conversation + tool outputs + scratchpad. Must fit in context window.

2 hours1 prereqs

Short-term memory = everything needed for this session, this task. The context window itself.

Composition:

  • System prompt (fixed)
  • User initial request
  • All tool calls + results
  • Model's intermediate thoughts (if any)

Anti-patterns:

  • Keeping a 5-page raw HTML tool result as-is
  • Sending the first 49 of a 50-turn conversation every time
  • Accumulating tool results without summarizing
