Raw Blame History

phase: 33-persistent-memory plan: 02 subsystem: ui tags: [personal-assistant, mode-gating, react-query, chat-ui, nexus-mode]

requires:

  • phase: 30-hardware-detection-mode-selection provides: fetchNexusSettings, NexusMode types, /api/nexus/settings endpoint
  • phase: 21-chat-foundation provides: chatApi, ChatConversationListItem, ChatMessage types provides:
  • useNexusMode hook with isAssistantEnabled flag
  • assistantMemoryApi client for /assistant-memory/:companyId endpoints
  • PersonalAssistant page with full-page chat UI and mode gating
  • /assistant and /assistant/:conversationId routes in boardRoutes()
  • Sidebar Assistant link gated by isAssistantEnabled affects:
  • ui/src/App.tsx
  • ui/src/components/Sidebar.tsx
  • ui/src/lib/queryKeys.ts

tech-stack: added: [] patterns: - useNexusMode wraps fetchNexusSettings with useQuery, defaults to 'both' while loading - Mode gate: isAssistantEnabled = mode !== 'project_builder' - PersonalAssistant uses chatApi directly (no ChatPanel dependency) for standalone full-page chat - Optimistic user message insertion + SSE streaming via chatApi.postMessageAndStream - "Turn into project" button present but disabled with Coming soon tooltip (Plan 03 wires handoff)

key-files: created: - ui/src/hooks/useNexusMode.ts - ui/src/api/assistantMemory.ts - ui/src/pages/PersonalAssistant.tsx - ui/src/api/hardware.ts (checked out from phase-33 branch as prerequisite) - ui/src/api/chat.ts (checked out from phase-33 branch as prerequisite) modified: - ui/src/App.tsx - ui/src/components/Sidebar.tsx - ui/src/lib/queryKeys.ts

decisions:

  • "PersonalAssistant builds its own chat UI from chatApi directly rather than importing ChatPanel (which lives in phase-21 branch not available in this worktree)"
  • "useNexusMode defaults mode to 'both' while loading to avoid flash-redirect on initial mount"
  • "Assistant NavLink placed between Dashboard and Inbox in sidebar — prominent discovery position"
  • "Prerequisite files (hardware.ts, chat.ts) checked out from gsd/phase-33-persistent-memory branch to satisfy plan dependencies"
  • "nexus.settings query key added to queryKeys.ts for cache coherence with other components that may read nexus settings"

Phase 33 Plan 02: Personal Assistant Page + Mode Hook Summary

One-liner: Personal Assistant full-page chat UI with useNexusMode hook (isAssistantEnabled), assistantMemoryApi client, /assistant route, and mode-gated sidebar link.

Performance

  • Duration: ~12 min
  • Completed: 2026-04-01
  • Tasks: 2
  • Files modified: 8

Accomplishments

Task 1: Core hooks, API client, and page

  • ui/src/hooks/useNexusMode.ts — React Query hook fetching /api/nexus/settings, exposes isAssistantEnabled = mode !== "project_builder", defaults to "both" while loading
  • ui/src/api/assistantMemory.ts — assistantMemoryApi with getMemory, appendFact, clearMemory methods targeting /assistant-memory/:companyId
  • ui/src/pages/PersonalAssistant.tsx — Full-page chat layout with:
    • Left panel: conversation list with New button
    • Right panel: message display (streaming-ready) + input bar (Enter-to-send, Shift+Enter newline)
    • Header: "Personal Assistant" title + disabled "Turn into project" button (Plan 03 stub)
    • Mode gate: redirects to /dashboard when !isAssistantEnabled
    • Optimistic user message insertion + SSE streaming via chatApi.postMessageAndStream
  • Added nexus.settings key to queryKeys.ts

Task 2: Route wiring and sidebar link

  • Added lazy import for PersonalAssistant in App.tsx
  • Added routes /assistant and /assistant/:conversationId inside boardRoutes()
  • Added Bot icon import and useNexusMode hook to Sidebar.tsx
  • isAssistantEnabled gates the "Assistant" NavLink — hidden when mode is project_builder

Deviations from Plan

Auto-fixed Issues

1. [Rule 3 - Blocking] Prerequisite files missing from parallel worktree

  • Found during: Task 1 setup
  • Issue: This worktree (worktree-agent-a9598a48) is based on commit 4c8cfcd8 (phase 4), which predates the phase-21 chat system and phase-30 hardware/nexus settings files. The plan references hardware.ts (NexusMode types) and chatApi but they didn't exist in the worktree.
  • Fix: Used git checkout gsd/phase-33-persistent-memory -- ui/src/api/hardware.ts ui/src/api/chat.ts ui/src/App.tsx ui/src/components/Sidebar.tsx ui/src/lib/queryKeys.ts to bring prerequisite files into the worktree from the correct branch baseline
  • Files modified: hardware.ts, chat.ts, App.tsx, Sidebar.tsx, queryKeys.ts (checked out, not created)
  • Commit: Included in cd8d54a5 (Task 1)

2. [Rule 1 - Bug] PersonalAssistant uses ChatConversationListItem not ChatConversation

  • Found during: Task 1 (type checking)
  • Issue: chatApi.listConversations returns ChatConversationListResponse with items: ChatConversationListItem[], not ChatConversation[]
  • Fix: Updated type annotations in ConversationListProps and conversations state variable to use ChatConversationListItem
  • Files modified: ui/src/pages/PersonalAssistant.tsx
  • Commit: cd8d54a5

3. [Rule 1 - Bug] Missing required fields in optimistic ChatMessage

  • Found during: Task 1 (type checking)
  • Issue: Optimistic message creation was missing agentId: null and messageType: null required by the ChatMessage interface
  • Fix: Added all required ChatMessage fields to the optimistic update object with a satisfies ChatMessage assertion
  • Files modified: ui/src/pages/PersonalAssistant.tsx
  • Commit: cd8d54a5

Known Stubs

"Turn into project" button — ui/src/pages/PersonalAssistant.tsx line 269

  • Intentional stub per plan spec: button present but disabled with tooltip "Coming soon"
  • Plan 03 wires the actual assistant→project handoff
  • Does not prevent the plan's goal (assistant page with chat works fully)

TypeScript Verification

  • Worktree lacks node_modules (parallel execution setup) — cannot run tsc directly in worktree
  • Verified against main /opt/nexus installation: tsc -b ui/tsconfig.json --noEmit
  • Zero new TypeScript errors introduced by plan-02 changes
  • Pre-existing error in AgentConfigForm.tsx (detectModel) is out-of-scope and pre-dates this plan
