Enforce agent state transitions at compile time via enum-carried data#77
Conversation
Move state-specific fields (active_stream, pending_tool_calls, tool_responses) into StreamState enum variants so the compiler prevents accessing data that only exists in a particular state. This eliminates runtime state guards in submit_tool_result and makes invalid field access a compile error rather than a logic bug. https://claude.ai/code/session_014n42dEnaKvcjB6Qj4Pw7PM
Move streaming_text, streaming_thinking, mode, and retry_attempt out of Agent into a TurnState struct. These fields only exist while processing a request and are dead weight when idle. Agent now has phase/turn as paired Options (both Some while processing, both None when idle) rather than scattered loose fields. Also capture last_result on turn completion so last_message() works after the turn state is consumed. https://claude.ai/code/session_014n42dEnaKvcjB6Qj4Pw7PM
