Write Stage — Creating Context: Memory, Retrieved Docs, Tool Results, History
~12 min read
Writing context means saving information OUTSIDE the active context window so it can help an agent perform a task later — to long-term memory, short-term memory, or a state object, rather than trying to keep everything live at once.

Key points
- •Writing context means saving information OUTSIDE the active context window, so it's available for later steps or later sessions
- •3 write destinations: long-term memory (across sessions), short-term memory (within a session), and a state object (multi-step task progress)
- •Worth writing: memory outputs, retrieved documents, tool results, and relevant conversation history — not everything indiscriminately
- •Being selective at write time reduces the cleanup burden the later Compress stage would otherwise have to do
- •Writing is the foundation stage — there's nothing to Select, Compress, or Isolate later if nothing was durably written first
