Allow Roo to search previous task content?

[shadow3aaa]

Currently, if a new task is started, Roo will have no knowledge of previous modifications. Reading and analyzing the source code from scratch each time leads to repetitive actions and makes it difficult to handle tasks that require continuity. On the other hand, completing everything within a single task results in overly long context, which negatively affects performance.

What if we treat the task history as a document and make it searchable for Roo? That way, we can avoid these issues without having to insert the entire history into the context directly.
