-No active task. First classify the current turn and ask for task-creation consent before creating any Trellis task.
+No active task pointer. First classify the turn and inspect directly related tasks; a missing pointer does not mean no suitable task exists.
 Pure consultation or a small isolated edit: respond or execute within scope without asking to create a task.
-Complex task: ask the user if you can create a Trellis task and enter the planning phase. If the user says no, explain, clarify scope, or suggest a smaller split.
+Reuse a suitable task and activate already approved work with the official task command. New scope still needs review; ask for task creation only when no suitable owner exists and creation is not already authorized.

+Read the current PRD, applicable design decisions and latest implementation status; load relevant spec sections and reuse unchanged context. Continue approved work through its checks. Independent review remains a separate gate; commit, push, archive and production actions require their existing explicit authorization.
