GOAL
Developer wanted to know whether ChatTranscript.vue actually streams output token-by-token, and asked the agent to trace how the streaming state and message updates flow through the frontend and bridge layers.
- +0Prompt · +0Is ChatTranscript.vue currently doing streaming output?
- +0mAgent did · +0mRead ChatTranscript.vue and searched for isStreaming/transcript usage across AppMainContent.vue and useBridgeClient.ts, then inspected transcript event types in bridge/types.ts
- +0mAgent did · +0mRe-read ChatTranscript.vue in full, searched for isStreaming usage in App.vue, and traced upsertTranscriptMessage and replaceTranscript logic in useBridgeClient.ts
- +1mAgent did · +1mTraced ws-rpc-adapter.ts's projectLifecycleEvent/handleTranscriptLifecycleEvent handling of message_start/message_update/message_end events, extractEventMessage helper, and related test expectations
- +2mAgent did · +2mSearched for isStreaming prop wiring between App.vue and AppMainContent.vue/ChatTranscript.vue via useBridgeClient() to confirm how agent_start/agent_end toggle the flag
- +3mOutcome · +3mAnswered: the pipeline is streaming in the sense of incremental message upserts (transcript_upsert -> upsertTranscriptMessage) keyed by transcriptKey, not a component-level typewriter effect; isStreaming is toggled by agent_start/agent_end events
VERDICT
I'd start by pointing the agent straight at useBridgeClient.ts and ws-rpc-adapter.ts instead of letting it discover the RPC layer through several rounds of grepping from the Vue component outward. No corrections were needed here, it was a pure read-only investigation, but I could have saved a few minutes by naming the transcript_upsert/message_start/message_end events up front.
