Stateless

Carries no information forward. The model is stateless across model provider requests — each request resends the full context window, because the model has no way to see anything else. An agent is stateless across sessions by default: a new session starts empty, with no trace of prior ones. Counterpart to stateful.

Usage:

"Why does it forget the convention every time I clear?"

"The model's stateless — the new session starts empty. If you want it carried, write it to AGENTS.md or a memory file the harness loads at session start."
