Create session with specified ID

[Rhain]

When creating a session, I want to customize the ID by obtaining parameters from the session creation process and use the custom ID to create the session.

just curious, what is the use case here?

When you want to have other scripts run and use opencode but want to set the "session" to something determentic that you can control from somewhere else

I would like the agent to know its own session ID (or be able to fetch it through an internal tool), such that it can provide its session id to an external MCP tool. The MCP server can use the session ID to identify the "user" when it holds persistent data on behalf of the agent.

I'd be happy to contribute this feature. It's mostly already implemented
