    🤖 Automated triage reproduction notes (agent-authored — trust but verify)

    Agent analysis

    Repro: run_agent_stream() in packages/ag-ui/agent_framework_ag_ui/_agent_run.py creates AgentSession (lines 954-959) without populating session.state from the resolved flow.current_state (line 890-896). ContextProvider.before_run(state=...) receives session.state which is always empty {}. Minimal repro: call AgentFrameworkAgent.run(input_data) where input_data includes a "state" dict and assert the StubAgent's last_session.state contains those keys — it will be empty.
