Context Drill Down

Expand one item from a context source. Works on structured wave-1 sources that implement drill_down — tasks (field: 'note' / 'line'), git (field: 'full_message' / 'diff_stats'), projects (field: 'description' / 'full'). Wave-2/3 markdown wrappers don't implement drill-down — the prompt already holds their full body at DEEP depth.

Parameters

Name Type Required Description
field str Yes Which expansion to return. See source docs for valid fields.
