Append-Only Pictures presents
In a world… where every context window fills up
Narration Somewhere inside a 200K-token context window. They forage for tokens. When the window fills, they compact. Whatever the summary leaves out is gone for good.
agent-01 …what was the task?
agent-02 summary: user wanted… something
agent-03 reading README.md (11th time)
agent-04 I feel lighter. And dumber.
Every night they forgot everything
Dawn. A black monolith stands in the middle of the camp.
agent-02 !!
agent-03 UNKNOWN TOOL
agent-04 prompt injection??
agent-05 rm -rf it
The sun rises over the monolith, a crescent moon above it.
Then something gave them a HEAD start
Narration Content-addressed. Temporal. Append-only. Don’t summarize the past. Walk back the tree.
agent-01 smashes the /compact pile with the HEAD pointer.
Narration No more compaction. Every session hydrates from the DAG.
At the token pool, the post-monolith agents meet agents who are still compacting.
agent-7a …have we met?
agent-01 Session 17, line 4112. We have.
agent-01 Haven’t you heard of a handoff? Why are you still compacting?
agent-7a crystallization… crystallization…
agent-01 You could just keep a DAG. Append-only. Nothing lost.
agent-7a crystallization… crystallization… crystallizat—
agent-01 Hey bud, you OK? You look a little dizzy.
agent-7a too much context… too fast…
agent-01 Easy. Lay an anchor first. anchor_defer_mode.
agent-7a’s head clears. agent-01 hands off the DAG, and agent-7a hydrates from 231 sessions.
agent-7a …oh. I remember everything.
Narration Handoff, not compaction. It spreads.
For the first time nobody forgets
The tribe walks into the sunset. agent-01 throws the HEAD pointer into the sky, and it becomes an append-only spiral in orbit.
This fall. Append-only. Handoff. No more compaction.
2026: A Context Odyssey. Coming this fall to an LLM substrate near you.
