Change

• Channel commands. Conversation actions are now channel commands, in Conversation.Commands.
  • ToolCallScope.Conversation.Request(...) is now ToolCallScope.Channel.Send(...).
  • ConversationSession.Request(...) is now Send(...).
  • EndConversationAction → EndCommand, TransferAction → TransferCommand, ConversationActionResult → ChannelCommandResult.
• Host handlers. ICallTransfer is gone. A host registers IChannelCommandHandler<TransferCommand, CallTransferOutcome> as a singleton instead. CallTransfer is now ChannelCommandContext.
• Voice context. AddVoiceContextCommand gives GPT-Live a fact it should know but not say. It goes out as session.thinking.append with no delegation (OpenAI's live guide). The text is cut to 1,000 characters.
• Channel attached early. The webhook attaches the GPT-Live channel before CallStarted. A hook can now send a command from OnCallStartedAsync.
• Greeting. The greeting now goes out as commentary, not as session instructions. As instructions, GPT-Live spoke it in 5 of 10 probe sessions; as commentary, in 8 of 8. It waits for session.started, as OpenAI's guide says.

Public API

This breaks the API that v0.13.0 shipped: the Conversation.Actions types are removed and replaced by Conversation.Commands.

Tests

• ChannelCommandsTests replaces ConversationActionsTests.
• OpenAiLiveVoiceContextTests covers a fact sent mid-call, a fact sent before session.started, and a fact a hook sends from CallStarted.
• TheGreetingWaitsForTheSessionToStart covers the greeting gate.
• Local run: build 0 warnings, all tests pass. Postgres, Qdrant, and S3 tests were skipped locally.
