Requirements: Chat Agent WebApp
Defined: 2026-03-27 Core Value: A working, well-understood AI chat interface — every line of code is intentional and explained
v1 Requirements
Chat Core
- CHAT-01: User can type a message and send it to the OpenAI GPT API
- CHAT-02: User receives the AI response displayed in the chat area
Conversation Management
- CONV-01: User can create a new conversation
- CONV-02: User can switch between existing conversations
- CONV-03: User can delete a conversation
- CONV-04: Conversations persist to JSON files and survive app restarts
Message Display
- DISP-01: AI responses render as formatted markdown (headings, lists, bold, links)
- DISP-02: Code blocks in AI responses display with syntax highlighting
- DISP-03: User can copy a message to clipboard
UI/Layout
- UI-01: App has sidebar with conversation list and main chat area
- UI-02: Chat area has text input with send button
- UI-03: App layout is responsive across screen sizes
Code Quality
- CODE-01: Every Blazor concept introduced has inline comments explaining what and why
- CODE-02: Each phase introduces one concept incrementally (tutorial-style progression)
v2 Requirements
Streaming
- STRM-01: AI responses stream token-by-token in real time
- STRM-02: User can cancel an in-progress AI response
- STRM-03: Loading/typing indicator shows during AI generation
Agentic Workflows
- AGNT-01: LangChain integration for workflow orchestration
- AGNT-02: RAG pipeline for document retrieval
- AGNT-03: MCP server integration for tool use
Enhanced Features
- ENH-01: Auto-generated conversation titles from first message
- ENH-02: System prompt configuration per conversation
- ENH-03: Model selector (GPT-4o, GPT-4o-mini, etc.)
- ENH-04: Dark/light theme toggle
- ENH-05: Auto-scroll during message display
- ENH-06: Visual distinction between user and AI messages (styled bubbles)
Out of Scope
| Feature | Reason |
|---|---|
| Authentication/login | Single user, no auth needed |
| Database storage | JSON files sufficient for personal use |
| Deployment/hosting | Local development only for v1 |
| Multi-user support | Personal tool |
| OAuth/third-party login | Not needed |
| Voice input/output | Complexity, not core to chat value |
| Image/multimodal input | Defer to v2+ |
| Real-time collaboration | Single user |
| Mobile app | Web-first |
