# PreCompact Entrypoint

# This entrypoint orchestrates all PreCompact handlers when Claude Code is about to compact the transcript.
# It reads JSON input from STDIN, executes all configured handlers, merges their outputs,
# and returns the final result to Claude Code via STDOUT.

# require_relative '../handlers/pre_compact/transcript_backupper'
# require_relative '../handlers/pre_compact/insight_extractor'
# require_relative '../handlers/pre_compact/summary_generator'
