Does every thread have its own session with memory?

is every thread a fresh session? does it have memory?

Generally, yes: one Discord thread maps to one OpenCode session.

• The first actionable message in a thread creates a session.
• Follow-up messages in that same thread reuse the session, so the model retains that thread’s conversation history.
• The thread→session mapping is persisted in Kimaki’s database, so it can survive bot restarts.
• A new thread creates a fresh session and does not automatically inherit the conversation from another thread. /new-session also creates a new thread/session.

There is also project-level memory:

• Threads working in the same checkout see the same files and code changes.
• If the project has a MEMORY.md, Kimaki injects its heading overview into new sessions, and the agent can read/update it. This provides durable, cross-thread knowledge—but it is file-based memory, not automatic recall of every previous conversation.
• Worktree sessions may have a separate checkout, so file state can differ.
