Summary

  • stop the Claude stop hook from printing non-decision JSON to stdout while keeping the backend COMPLETE status update
  • send hook errors to stderr and return cleanly so Claude sees a valid empty stop-hook response
  • add a regression test that proves the stop hook stays silent on stdout

Test Plan

  • python3 -m pytest -o addopts='' /private/tmp/codegen-sdk/tests/unit/codegen/cli/test_claude_session_stop_hook.py

Closing this because the upstream repo identity needs to be clarified before proposing the fix.
