# IMPORTANT: LEGACY V0 CODE
# This file is part of the legacy (V0) implementation of OpenHands and will be removed soon as we complete the migration to V1.
# OpenHands V1 uses the Software Agent SDK for the agentic core and runs a new application server. Please refer to:
# - V1 agentic core (SDK): https://github.com/OpenHands/software-agent-sdk
# - V1 application server (in this repo): openhands/app_server/
# Unless you are working on deprecation, please avoid extending this legacy file and consult the V1 codepaths above.
