4. User can click Stop to cancel an in-progress streaming response
5. User can edit a previous message to regenerate the response, or click Retry on any existing assistant message; conversations with 1,000+ messages scroll without jank via a virtualized list
6. Slash commands (`/brainstorm`, `/ask-pm`, `/ask-engineer`, `/task`, `/search`) route messages to the correct agent; `@mention` syntax routes to the named agent

- [Phase 22-agent-streaming]: Use fetch ReadableStream instead of EventSource for POST SSE streaming endpoint
- [Phase 22-agent-streaming]: streamEcho stub yields word-by-word with 50ms delay; Phase 23 replaces with real LLM adapter

- [Phase 22-agent-streaming]: isAnyStreaming prop (not isStreaming) distinguishes global streaming state for disabling edit/retry globally in ChatMessage

phase: 22-agent-streaming
plan: "03"
subsystem: ui
tags: [react, streaming, chat, edit, retry, stop-button, tooltips]
# Dependency graph
requires:
- phase: 22-02
provides: ChatMessage with agentName/identity bar, ChatStreamingCursor, group-hover div wrapper
provides:
- ChatStopButton component (centered outline button with Square icon)
- ChatMessageActions component (edit Pencil for user, retry RefreshCw for assistant)
- ChatMessage extended with inline edit mode, isAnyStreaming, onEdit/onRetry callbacks
affects:
- 22-04 (ChatPanel integration — will wire onEdit/onRetry/stop callbacks)
- Any component that renders ChatMessage
# Tech tracking
tech-stack:
added: []
patterns:
- group-hover pattern for hover-triggered action buttons on chat bubbles
- isAnyStreaming gate — passes to ChatMessageActions to globally disable edit/retry during streaming
- inline edit mode with useState(isEditing) + useState(editValue) in ChatMessage
key-files:
created:
- ui/src/components/ChatStopButton.tsx
- ui/src/components/ChatMessageActions.tsx
modified:
- ui/src/components/ChatMessage.tsx
- ui/src/components/ChatMessage.test.tsx
key-decisions:
- "isAnyStreaming prop added to ChatMessage (not isStreaming) — distinguishes 'this msg is streaming' from 'any msg is streaming' for disabling global edit/retry"
- "ChatMessageActions returns null when isStreaming — clean conditional render, no CSS toggling"
patterns-established:
- "Pattern: group-hover action buttons — parent div has 'group' class, action buttons use 'hidden group-hover:flex' to show on hover"
- "Pattern: inline edit mode — useState(isEditing) in ChatMessage; textarea pre-filled with content; Save calls onEdit(id, newContent)"

# Phase 22 Plan 03: Message Action Controls Summary
**Edit/retry/stop controls wired to ChatMessage — user messages get inline edit textarea, assistant messages get retry RefreshCw, stop button component ready for ChatPanel.**
## Performance
- **Duration:** ~3 min
- **Started:** 2026-04-01T18:22:48Z
- **Completed:** 2026-04-01T18:25:20Z
- **Tasks:** 2 completed
- **Files modified:** 4
## Accomplishments
- ChatStopButton: centered outline button with Square (filled) icon, border-t container, aria-label for accessibility
- ChatMessageActions: Pencil edit at top-right of user bubble (absolute, group-hover), RefreshCw retry below assistant message (right-aligned, group-hover); both hidden when isStreaming
- ChatMessage extended with inline edit mode (textarea + Save/Discard), isAnyStreaming global gate, onEdit/onRetry callback props
