Session Catchup Script for planning-with-files
Session-agnostic scanning: finds the most recent planning file update across
ALL sessions, then collects all conversation from that point forward through
all subsequent sessions until now.
Supports multiple AI IDEs:
- Claude Code (.claude/projects/)
- OpenCode (.local/share/opencode/storage/)
Automatic callers use no-history mode and never inspect host session stores.
Aggregate metadata and transcript excerpts require explicit requests.
Usage: python3 session-catchup.py [--no-history|--metadata|--replay] [project-path]
