Manual Context Control: Manual Control Over Context Compression #849

Duplicate of #856

This issue has been merged into Task Tree Abstraction (#856).

Original Problem

Context window gets too long, requiring manual compression / viewing compressed history.

How Task Tree Solves This

Task Tree abstraction provides tree-aware context compression:

• Auto-compression when subtasks complete (based on tree structure)
• Manual tools: compress_context(), view_compressed_history()
• Context pruning based on task hierarchy (completed siblings compressed, active tasks full history)

See #856 for full design.
