Threads
Threads are individual conversations inside a channel, each with its own context and an auto-generated summary. Start, find, and use threads in Nebula.
A thread is a single conversation inside a channel. Every channel can hold many threads — one per topic, request, or working session — and Nebula writes a short summary at the top of each so you can pick up where you left off.
Why threads
Threads keep work organized and keep agents focused. Each thread has its own context, so agents don't drag yesterday's discussion into today's request — and you can scan a channel and instantly see what's been happening.
One topic per thread
Keeps the conversation tight. New question? New thread.
Auto-summary at the top
Nebula writes a short blurb so anyone joining late knows what's going on.
Separate context per thread
Agents respond based on the current thread, not the whole channel.
Scoped files & permissions
Files dropped into a thread stay there. Agents only see what's in the room.
Starting a thread
Open a channel. The thread list opens on the left.
Click + Start new thread at the top of the list.
Type your first message. Nebula will generate the thread's title and summary from it — refining both as the conversation grows.
"Context cleared"
When you open a brand-new thread, you'll see a small Context cleared marker. That's Nebula confirming the agent isn't carrying over anything from the previous thread — fresh slate, fresh response.
If you want to clear context inside a long-running thread (say, switch topics mid-conversation), type /clear and Nebula resets just that thread's working memory. Files, summary, and history stay — only the agent's short-term context resets.
Replying & mentioning
Anyone in the channel can reply in a thread. Use @Nebula or @teammate to pull in agents or people who aren't already watching.
Stuck? Ask Nebula directly inside the thread — it can do things like rename the thread, invite an agent, or summarize the conversation for you.
Or start one in chat
Start a new thread in #grad-party about venue options under $2,000.
Started — the new thread is open with the title 'Venues under $2,000'. I'll begin researching now and post findings as I go.
