Long conversations drift. The assistant forgets the early details, replies slow down, and you start repeating yourself. A fresh thread helps, if you bring the right context with you.
Every assistant has a limit on how much of the conversation it can hold in view at once. As a thread grows, early messages get less attention or fall out entirely. The symptoms are familiar: contradicted decisions, forgotten constraints, answers that ignore something you said an hour ago.
It works well, as long as you do it before the thread gets too tangled to summarise.
If you save your chats as you go, you can reopen any saved conversation and pick up exactly where you left off in a fresh thread, with the context already assembled. Stash does this from the pill on the chat, and it can also pull a related past conversation into your prompt as context, so the new thread starts informed.
