Clear / New
Clears the entire conversation and starts from scratch. Everything in the context window is gone—summaries, code references, prior decisions, all of it.
Useful when context gets too polluted to salvage—spiraling loops, context collapse, or accumulated noise from failed attempts.
Also useful proactively between discrete tasks. Write an article, clear, write another. Prevents context contamination where unrelated work bleeds together.
Rewinding is less drastic when only recent context went wrong.
