+# Bug 140: Activity status indicator never visible due to display condition
+
+## Description
+
+Story 86 wired up live activity status end-to-end (server emits tool_activity events over WebSocket, frontend receives them and calls setActivityStatus), but the UI condition `loading && !streamingContent` on line 686 of Chat.tsx guarantees the activity labels are never visible.
+
+The timeline within a Claude Code turn:
+1. Model starts generating text → onToken fires → streamingContent accumulates → streaming bubble shown, activity indicator hidden
+2. Model decides to call a tool → content_block_start with tool_use arrives → setActivityStatus("Reading file...") fires
+3. But streamingContent is still full of text from step 1 → condition !streamingContent is false → activity never renders
+4. onUpdate arrives with the complete assistant message → setStreamingContent("") → now !streamingContent is true, but the next turn starts immediately or loading ends
+
+The "Thinking..." fallback only shows in the brief window before the very first token of a request arrives — and at that point no tool has been called yet, so activityStatus is still null.
+
+## How to Reproduce
+
+1. Open the Story Kit web UI chat
+2. Send any message that causes the agent to use tools (e.g. ask it to read a file)
+3. Watch the thinking indicator
+
+## Actual Result
+
+The indicator always shows "Thinking..." and never changes to activity labels like "Reading file...", "Writing file...", etc.
+
+## Expected Result
+
+The indicator should cycle through tool activity labels (e.g. "Reading file...", "Executing command...") as the agent works, as specified in Story 86's acceptance criteria.
+
+## Acceptance Criteria
+
+- [ ] Activity status labels (e.g. 'Reading file...', 'Executing command...') are visible in the UI when the agent calls tools
+- [ ] Activity is shown even when streamingContent is non-empty (e.g. between assistant turns or alongside the streaming bubble)
+- [ ] The indicator still falls back to 'Thinking...' when no tool activity is in progress
