+Follow-up TODOs: None +================================================================================ +--> + +# Chatbot Phase 3 Constitution + +## Core Principles + +### I. Stateless Server Architecture +Server maintains NO state in memory. Every request must be independently processable with all conversation state persisted in PostgreSQL database. Enables horizontal scaling, fault tolerance, and resilience. + +### II. MCP-First Tool Design +All task operations exposed ONLY through MCP tools (5 total: add, list, complete, delete, update). Direct database calls from chat endpoint are forbidden. Standardized interface for AI agent interaction. + +### III. AI Agent Orchestration +OpenAI Agents SDK orchestrates all tool calls. Agent analyzes user intent and selects appropriate tools based on natural language understanding. No manual if-else routing in chat endpoint. + +### IV. Conversation Persistence +Every message stored in database with conversation context. Chat history survives server restarts and enables multi-device access. Conversation and Message tables with proper relationships. No in-memory conversation buffers. + +### V. Security-First JWT Authentication +Every chat request must include valid JWT token. User isolation and authorization enforcement through Better Auth JWT integration from Phase 2. All MCP tools verify user_id from token. + +## Technology Stack (Non-Negotiable) + +### Frontend +- **Framework**: OpenAI ChatKit (purpose-built for conversational AI interfaces) +- **Configuration**: Domain allowlist required for production + +### Backend +- **Framework**: Python FastAPI (async support, modern Python, excellent OpenAPI integration) + +### AI Layer +- **Framework**: OpenAI Agents SDK (official SDK with tool calling support) +- **Model**: GPT-4 or GPT-4-Turbo + +### MCP Server +- **Framework**: Official MCP SDK (Python) (standard protocol for AI-tool communication) + +### Database +- **Service**: Neon Serverless PostgreSQL (from Phase 2) +- **ORM**: SQLModel (async support, Pydantic integration, type safety) + +### Authentication +- **Service**: Better Auth (from Phase 2) +- **Token**: JWT with 7-day expiry + +## Database Schema Requirements + +### New Tables (Phase 3) + +#### Conversation Table +```sql +CREATE TABLE conversations ( + id SERIAL PRIMARY KEY, + user_id VARCHAR(255) NOT NULL, + created_at TIMESTAMP DEFAULT NOW(), + updated_at TIMESTAMP DEFAULT NOW(), + FOREIGN KEY (user_id) REFERENCES users(id) ON DELETE CASCADE, + INDEX idx_user_conversations (user_id, created_at DESC) +); +``` + +#### Message Table +```sql +CREATE TABLE messages ( + id SERIAL PRIMARY KEY, + conversation_id INTEGER NOT NULL, + user_id VARCHAR(255) NOT NULL, + role VARCHAR(20) NOT NULL CHECK (role IN ('user', 'assistant')), + content TEXT NOT NULL, + tool_calls JSONB, + created_at TIMESTAMP DEFAULT NOW(), + FOREIGN KEY (conversation_id) REFERENCES conversations(id) ON DELETE CASCADE, + FOREIGN KEY (user_id) REFERENCES users(id) ON DELETE CASCADE, + INDEX idx_conversation_messages (conversation_id, created_at ASC) +); +``` + +### Existing Tables (Phase 2) +- **tasks**: Already exists with user_id foreign key +- **users**: Managed by Better Auth + +## MCP Tools Specification + +### Tool Contract Standards +- **Input Validation**: Pydantic models for all parameters +- **Error Handling**: Return structured error objects, never raise exceptions +- **User Isolation**: Every tool MUST filter by user_id from JWT +- **Idempotency**: Operations should be safe to retry +- **Response Format**: Consistent JSON structure across all tools + +### Required Tools (5 Total) + +#### 1. add_task +Parameters: + - user_id: str (from JWT) + - title: str (1-200 chars, required) + - description: str (0-1000 chars, optional) + +Returns: + { + "task_id": int, + "status": "created", + "title": str + } + +#### 2. list_tasks +Parameters: + - user_id: str (from JWT) + - status: str (optional: "all" | "pending" | "completed") + +Returns: + { + "tasks": [ + {"id": int, "title": str, "completed": bool, "created_at": str} + ], + "total": int + } + +#### 3. complete_task +Parameters: + - user_id: str (from JWT) + - task_id: int (required) + +Returns: + { + "task_id": int, + "status": "completed", + "title": str + } + +#### 4. delete_task +Parameters: + - user_id: str (from JWT) + - task_id: int (required) + +Returns: + { + "task_id": int, + "status": "deleted", + "title": str + } + +#### 5. update_task +Parameters: + - user_id: str (from JWT) + - task_id: int (required) + - title: str (optional, 1-200 chars) + - description: str (optional, 0-1000 chars) + +Returns: + { + "task_id": int, + "status": "updated", + "title": str + } + +## Security Requirements + +### JWT Token Validation +Every chat request MUST validate: +1.

AI Chatbot Foundation + +**Feature**: 004-chatbot-db-mcp +**Date**: 2026-01-09 +**Purpose**: Resolve technology choices and architectural decisions for implementation + +## Research Summary + +This document captures research decisions for implementing the Phase 3 chatbot foundation, focusing on database schema design for conversation persistence and MCP (Model Context Protocol) server architecture for task management tools. + +--- + +## Topic 1: Database Schema Design for Conversation Persistence + +### Decision: Two-table relational model with cascade deletion + +**Chosen Approach**: +- `conversations` table: Stores chat session metadata (id, user_id, created_at, updated_at) +- `messages` table: Stores individual message records with conversation foreign key +- Cascade deletion: Deleting a conversation automatically removes all messages +- Redundant user_id in messages table for query optimization + +**Rationale**: +1. **Separation of concerns**: Conversation metadata (timestamps, user ownership) separated from message content +2. **Query efficiency**: Indexing on conversation_id allows fast message retrieval per conversation +3. **Data integrity**: Foreign key constraints ensure referential integrity +4. **Cascade deletion**: Automatically cleans up messages when conversation deleted +5. **Multi-device access**: Centralized conversation state enables cross-device synchronization +6. **Performance optimization**: Redundant user_id index enables direct user message queries without joins + +**Alternatives Considered**: + +| Alternative | Pros | Cons | Rejected Because | +|-------------|------|------|------------------| +| Single table with JSONB column for messages | Simple schema, no joins | Difficult to query individual messages, no foreign key constraints, poor performance at scale | Messages table enables fine-grained queries and foreign key integrity | +| Document database (MongoDB) | Flexible schema, native JSON support | Additional technology stack, migration complexity from PostgreSQL | Project already uses PostgreSQL (Neon) from Phase 2 | +| Messages-only table (no conversations table) | Simpler structure | No way to track conversation metadata (timestamps, session grouping), difficult to implement multi-device sync | Conversations table enables session-level operations and metadata tracking | + +**Best Practices Applied**: +- Foreign key constraints for referential integrity +- Cascade deletion for automatic cleanup +- Composite indexes on (user_id, created_at) for efficient user queries +- CHECK constraint on role field to enforce enum-like behavior +- JSONB for flexible tool call metadata storage + +--- + +## Topic 2: MCP Server Architecture for Task Management + +### Decision: Async Python MCP server with Pydantic validation + +**Chosen Approach**: +- Official MCP Python SDK for server implementation +- Async/await pattern with FastAPI-style coroutines +- Pydantic models for all tool input/output validation +- Separate module per tool for maintainability +- Centralized server.py for tool registration and dispatch + +**Rationale**: +1. **Standard compliance**: Official SDK ensures MCP protocol compatibility +2. **Type safety**: Pydantic provides runtime validation and automatic error messages +3. **Performance**: Async/await enables non-blocking I/O for concurrent tool calls +4. **Maintainability**: Separate tool modules make code organization clear +5. **Error handling**: Standardized error response format across all tools +6. **Testing**: Modular structure enables isolated unit testing per tool + +**Alternatives Considered**: + +| Alternative | Pros | Cons | Rejected Because | +|-------------|------|------|------------------| +| REST API instead of MCP | Standard web pattern, easier testing | Breaks constitution principle #2 (MCP-First), requires custom tool registry | MCP is constitutionally required for AI agent integration | +| Synchronous MCP server | Simpler implementation | Blocks on database calls, poor performance under load | Async enables concurrent tool execution for multi-user scenarios | +| Single monolithic tool file | Fewer files to manage | Hard to maintain, difficult to test, poor code organization | Modular structure scales better as tools grow | + +**Best Practices Applied**: +- Pydantic BaseModel for all input validation +- Consistent error response format: `{success, data/error}` +- Error codes: INVALID_INPUT, NOT_FOUND, UNAUTHORIZED, DATABASE_ERROR +- User isolation enforced via user_id filtering in all queries +- Idempotent operations where possible (task updates) +- Never raise exceptions - return structured error objects + +--- + +## Topic 3: SQLModel vs SQLAlchemy for ORM + +### Decision: SQLModel (Pydantic + SQLAlchemy) + +**Chosen Approach**: +- SQLModel for database models +- Leverages Pydantic v2 for validation +- SQLAlchemy core for database operations +- Automatic migration via Alembic + +**Rationale**: +1. **Type safety**: Full IDE support with auto-completion +2. **Validation**: Pydantic automatically validates on input and output +3. **Documentation**: Models serve as both database schema and API contract documentation +4. **Async support**: Compatible with asyncpg for high performance +5. **Project consistency**: Already used in Phase 2 for Task model + +**Alternatives Considered**: + +| Alternative | Pros | Cons | Rejected Because | +|-------------|------|------|------------------| +| Pure SQLAlchemy | More control, established | No automatic validation, more boilerplate | SQLModel provides same power with less code | +| SQLAlchemy + Pydantic separate layers | Maximum flexibility | Duplicate model definitions (one for DB, one for API) | SQLModel eliminates duplication | + +--- + +## Topic 4: Error Handling Strategy + +### Decision: Never raise exceptions - return structured errors + +**Chosen Approach**: +- All tools return dict: `{success: bool, data: Any | None, error: dict | None}` +- Error dict: `{code: str, message: str}` +- Error codes limited to 4 types: INVALID_INPUT, NOT_FOUND, UNAUTHORIZED, DATABASE_ERROR +- Database exceptions caught and converted to DATABASE_ERROR +- Validation errors converted to INVALID_INPUT + +**Rationale**: +1. **MCP protocol compatibility**: MCP tools return results, not exceptions +2. **User experience**: Clear error messages for end users +3. **Security**: Never expose raw database errors +4. **Consistency**: Standard format across all 5 tools +5. **Debugging**: Error codes enable programmatic handling + +**Best Practices Applied**: +- Security by obscurity: Return NOT_FOUND instead of UNAUTHORIZED for missing resources +- Never include stack traces in error messages +- Log full errors server-side while returning safe messages to users +- Validate inputs before database operations (fail fast) + +--- + +## Topic 5: Database Indexing Strategy + +### Decision: Strategic indexes for query performance + +**Chosen Approach**: +- `idx_user_conversations`: (user_id, created_at DESC) - Fast retrieval of user's conversation list +- `idx_conversation_messages`: (conversation_id, created_at ASC) - Fast chronological message retrieval +- `idx_user_messages`: (user_id, created_at DESC) - Direct user message queries without joins + +**Rationale**: +1. **Query optimization**: All common queries supported by indexes +2. **Performance**: Meet 100ms query requirement from constitution +3. **Multi-column indexes**: Optimize for specific access patterns +4. **ASC/DESC sorting**: Match typical query patterns + +**Alternatives Considered**: + +| Alternative | Pros | Cons | Rejected Because | +|-------------|------|------|------------------| +| Single index on all columns | Simpler | Larger index size, slower writes, less effective for specific queries | Multi-column indexes optimize for actual query patterns | +| No indexes | Simpler schema | Performance degrades with message count | 10k messages per conversation requires indexed access | + +--- + +## Topic 6: Tool Call Metadata Storage + +### Decision: JSONB field in messages table + +**Chosen Approach**: +- `tool_calls` column as JSONB type in messages table +- Stores array of tool invocations: `[{name, parameters, result}]` +- Only populated for assistant messages when tools were called + +**Rationale**: +1. **Flexibility**: JSONB accommodates any tool structure +2. **Queryability**: JSONB indexing possible for future analysis +3. **Audit trail**: Tracks exactly which tools AI invoked +4. **Conversation context**: Enables replay or analysis of AI decision-making + +**Best Practices Applied**: +- PostgreSQL JSONB for efficient storage and querying +- Optional field (nullable) - not all messages have tool calls +- Type checking at application layer, not database level + +--- + +## Topic 7: Migration Strategy + +### Decision: Versioned migration scripts with upgrade/downgrade + +**Chosen Approach**: +- Migration 003_add_conversation_tables.py +- `upgrade()` function creates tables +- `downgrade()` function drops tables +- Run via `python migrations/003_add_conversation_tables.py upgrade/downgrade` + +**Rationale**: +1. **Reversibility**: Downgrade enables rollback if needed +2. **Reproducibility**: Versioned migrations track database state +3. **Simplicity**: No dependency on complex migration frameworks +4. **Phase alignment**: Extends existing migration pattern from Phase 2 + +**Alternatives Considered**: + +| Alternative | Pros | Cons | Rejected Because | +|-------------|------|------|------------------| +| Alembic migrations | Industry standard, automatic versioning | Additional dependency, complex setup | Simple script sufficient for this scope | +| Manual SQL execution | Maximum control | No version tracking, manual rollback risk | Versioned scripts provide safety net | + +--- + +## Conclusion + +All research topics resolved with clear decisions aligned to: +- Project constitution principles +- Phase 2 existing architecture +- Performance requirements (<500ms tools, <100ms queries) +- Security requirements (user isolation, no raw errors) +- Maintainability and testability goals + +**Next Steps**: Proceed to Phase 1 (data model, contracts, quickstart) and Phase 2 (tasks generation). diff --git

2026-01-09 +**Status**: Draft +**Input**: User description: "Phase 3 AI chatbot foundation: database schema for conversations/messages and MCP server with 5 task management tools" + +## User Scenarios & Testing *(mandatory)* + +### User Story 1 - Persistent Chat History (Priority: P1) + +Users can engage in multi-turn conversations with an AI assistant that remembers all interactions across sessions and devices. When a user returns to the chat, they see their full conversation history and can continue discussing tasks naturally. + +**Why this priority**: This is the foundation for all AI chat functionality. Without persistent conversations, users cannot maintain context across sessions, making the chatbot essentially useless for real-world task management. + +**Independent Test**: Can be fully tested by creating conversations, exchanging messages, logging out, logging back in, and verifying all messages remain accessible. + +**Acceptance Scenarios**: + +1. **Given** a new user account, **When** they send their first message, **Then** a new conversation is created and the message is stored +2. **Given** an existing conversation with 5 messages, **When** the user logs out and logs back in, **Then** all 5 messages appear in chronological order +3. **Given** a conversation across multiple devices, **When** the user switches devices, **Then** they see the same conversation history on all devices +4. **Given** a user deletes their account, **When** the account deletion completes, **Then** all their conversations and messages are permanently removed + +--- + +### User Story 2 - Create Tasks via Natural Language (Priority: P2) + +Users can add new tasks by describing them in plain language (e.g., "remind me to buy groceries tomorrow", "create a task for the meeting with Sarah"), and the AI understands and creates the task automatically. + +**Why this priority**: The primary purpose of the chatbot is task management. Users expect to speak naturally rather than filling out forms. + +**Independent Test**: Can be fully tested by sending various natural language phrases to add tasks and verifying tasks are created with correct titles. + +**Acceptance Scenarios**: + +1. **Given** an active conversation, **When** the user says "add groceries to my list", **Then** a task titled "groceries" is created +2. **Given** an active conversation, **When** the user says "remind me to call mom on Sunday", **Then** a task titled "call mom on Sunday" is created +3. **Given** an empty task list, **When** the user says "I need to finish the project report", **Then** a task is created with the exact phrase as the title +4. **Given** a user has no tasks, **When** they ask to add a task, **Then** the task is created and associated with their account only + +--- + +### User Story 3 - View and Manage Tasks via Chat (Priority: P3) + +Users can ask to see their tasks, mark them complete, update them, or delete them using natural language commands. The AI understands intent and performs the correct operation. + +**Why this priority**: Complete task management requires read, update, and delete operations. Users expect to manage their entire task list through conversation. + +**Independent Test**: Can be fully tested by creating multiple tasks, then using natural language to list, complete, update, and delete them, verifying each operation succeeds. + +**Acceptance Scenarios**: + +1. **Given** 3 tasks (2 pending, 1 completed), **When** the user asks "show my pending tasks", **Then** only the 2 pending tasks are displayed +2. **Given** a task with ID 3, **When** the user says "mark task 3 as done", **Then** the task is marked complete +3. **Given** a task titled "buy milk", **When** the user says "change that to buy almond milk", **Then** the task title is updated to "buy almond milk" +4. **Given** a task the user no longer needs, **When** the user says "delete task 5", **Then** the task is permanently removed from their list +5. **Given** User A has tasks and User B has different tasks, **When** User A asks "show my tasks", **Then** only User A's tasks are displayed (no cross-user data leakage) + +--- + +### Edge Cases + +- **User deletion cascade**: What happens to a user's conversations and messages when their account is deleted? + - **Expected**: All conversations and messages for that user are permanently removed via cascade deletion + +- **Conversation deletion**: What happens to messages when a conversation is deleted? + - **Expected**: All messages within that conversation are permanently removed via cascade deletion + +- **Cross-user access attempt**: What if a user tries to access another user's task? + - **Expected**: The system returns "task not found" (not "access denied") for security by obscurity + +- **Empty conversation**: What if a user sends a message to start a conversation? + - **Expected**: A new conversation is automatically created, and the message is saved to it + +- **Long message content**: What if a message exceeds character limits? + - **Expected**: The system stores the full content (no arbitrary limits) as long as database capacity allows + +- **Special characters in task titles**: What if task titles contain quotes, emojis, or special characters? + - **Expected**: Characters are stored exactly as provided and displayed correctly + +- **Malformed tool calls**: What if the AI generates invalid tool call data? + - **Expected**: The system rejects the operation and returns a structured error message + +## Requirements *(mandatory)* + +### Functional Requirements + +**Database and Persistence** + +- **FR-001**: System MUST create a new conversation when a user sends their first message +- **FR-002**: System MUST store every user message with conversation context, user ID, role, and timestamp +- **FR-003**: System MUST store every AI assistant response with conversation context, role, and timestamp +- **FR-004**: System MUST associate all messages with a specific conversation for historical context +- **FR-005**: System MUST support tool call metadata storage when AI performs actions +- **FR-006**: System MUST cascade-delete all messages when a conversation is deleted +- **FR-007**: System MUST cascade-delete all conversations and messages when a user account is deleted +- **FR-008**: System MUST retrieve conversation history in chronological order (oldest first) + +**Task Management via Standardized Tools** + +- **FR-009**: System MUST provide a tool to create new tasks with a title and optional description +- **FR-010**: System MUST validate task titles are between 1-200 characters +- **FR-011**: System MUST validate task descriptions are between 0-1000 characters +- **FR-012**: System MUST provide a tool to list tasks with optional status filter (all, pending, completed) +- **FR-013**: System MUST provide a tool to mark a task as completed +- **FR-014**: System MUST provide a tool to permanently delete a task +- **FR-015**: System MUST provide a tool to update task title and/or description (at least one required) +- **FR-016**: System MUST enforce user data isolation for all task operations + +**Security and Data Isolation** + +- **FR-017**: System MUST filter all task queries by user ID to prevent cross-user data access +- **FR-018**: System MUST verify task ownership before allowing modification or deletion +- **FR-019**: System MUST return "not found" instead of "access denied" for missing tasks to avoid information leakage +- **FR-020**: System MUST validate all user inputs before processing to prevent injection attacks + +**Error Handling** + +- **FR-021**: System MUST return structured success responses with operation result and data +- **FR-022**: System MUST return structured error responses with error code and message +- **FR-023**: System MUST use consistent error codes: INVALID_INPUT, NOT_FOUND, UNAUTHORIZED, DATABASE_ERROR +- **FR-024**: System MUST never expose raw database errors to users +- **FR-025**: System MUST validate all input parameters before database operations + +### Key Entities + +- **Conversation**: Represents a chat session between a user and AI assistant.
