Deactivate the sa ## Tips for Migration - Keep the original SK sample open while iterating on the AF equivalent; the code is intentionally formatted so you can copy/paste across SDKs. -- Threads/conversation state are explicit in AF. When porting SK code that relies on implicit thread reuse, call `agent.get_new_thread()` and pass it into each `run`/`run_stream` call. +- Threads/conversation state are explicit in AF. When porting SK code that relies on implicit thread reuse, call `agent.get_new_thread()` and pass it into each `run` call. - Tools map cleanly: SK `@kernel_function` plugins translate to AF `@tool` callables. Hosted tools (code interpreter, web search, MCP) are available only in AF—introduce them once parity is achieved. - For multi-agent orchestration, AF workflows expose checkpoints and resume capabilities that SK Process/Team abstractions do not. Use the workflow samples as a blueprint when modernizing complex agent graphs. diff --git a/python/samples/semantic-kernel-migration/chat_completion/03_chat_completion_thread_and_stream.py
