|
|
|
|
## Introduction
|
|
|
|
This document outlines the architectural approach for enhancing the Directus Task Management Suite with a web-based Visual Editor interface. Its primary goal is to serve as the guiding architectural blueprint for AI-driven development of a read-only proof of concept evolving to a full project management and knowledge base system.
|
|
|
|
**Relationship to Existing Architecture:**
|
|
This document supplements existing project architecture by defining how new components will integrate with current systems. The Visual Editor approach eliminates the need for custom Directus extensions while providing a modern, web-viewable task management interface.
|
|
|
|
### Existing Project Analysis
|
|
|
|
#### Current Project State
|
|
- **Primary Purpose:** AI-powered development ecosystem with task management via CLI
|
|
- **Current Tech Stack:** Directus CMS, MCP Protocol, TypeScript, Node.js, Task Master CLI
|
|
- **Architecture Style:** Service-oriented with MCP server extensions and agent-based workflows
|
|
- **Deployment Method:** Directus on Zeabur cloud platform, local MCP server
|
|
|
|
#### Available Documentation
|
|
- Comprehensive BMad planning documents in planning/ directory
|
|
- Existing Task Master setup documentation
|
|
- MCP server integration patterns
|
|
- Claude Code agent documentation
|
|
|
|
#### Identified Constraints
|
|
- Must preserve existing Directus collections and data (3 projects, 2 tasks, 11 tags)
|
|
- Must maintain compatibility with 164+ existing MCP tools
|
|
- Cannot disrupt current Task Master CLI workflows
|
|
- Must support future evolution to full PM/KB system
|
|
|
|
## Enhancement Scope and Integration Strategy
|
|
|
|
### Enhancement Overview
|
|
**Enhancement Type:** Brownfield Web Interface Foundation
|
|
**Scope:** Read-only proof of concept evolving to full project management and knowledge base
|
|
**Integration Impact:** Low-risk addition to existing ecosystem
|
|
|
|
### Integration Approach
|
|
|
|
**Code Integration Strategy:** MCP server extension pattern - add new tools alongside existing 40+ tools without disrupting current workflows
|
|
|
|
**Database Integration:** Leverage existing Directus collections with minimal additive fields
|
|
|
|
**API Integration:** Use existing Directus GraphQL/REST APIs, extend MCP server with read-focused tools
|
|
|
|
**UI Integration:** Standalone web application with Visual Editor for inline task/project editing
|
|
|
|
### Compatibility Requirements
|
|
- **Existing API Compatibility:** Full backward compatibility - all current MCP tools continue unchanged
|
|
- **Database Schema Compatibility:** Additive fields only, no modifications to existing schema
|
|
- **UI/UX Consistency:** Visual Editor provides modern web interface while preserving CLI workflows
|
|
- **Performance Impact:** Minimal - read operations with smart caching, no impact on current workflows
|
|
|
|
## Tech Stack Alignment
|
|
|
|
### Existing Technology Stack
|
|
|
|
| Category | Current Technology | Version | Usage in Enhancement | Notes |
|
|
|----------|-------------------|---------|---------------------|-------|
|
|
| **CMS Platform** | Directus | Latest | Core data management | Already running at enias.zeabur.app |
|
|
| **Database** | PostgreSQL/MySQL | Directus managed | Existing collections | 26 custom collections operational |
|
|
| **API Layer** | Directus REST/GraphQL | Built-in | Task/project queries | Existing auth & permissions |
|
|
| **Integration** | MCP Protocol | Latest | Tool extensions | 164+ existing tools proven pattern |
|
|
| **Runtime** | Node.js | 18+ | Web app and MCP tools | Matches existing stack |
|
|
| **Language** | TypeScript/JavaScript | Latest | New components | Consistent with existing |
|
|
| **Authentication** | Directus Auth | Built-in | User management | JWT token-based |
|
|
| **Web Framework** | Visual Editor | Latest | Inline editing UI | No custom extensions needed |
|
|
|
|
### New Technology Additions
|
|
|
|
**None Required** - The enhancement leverages the existing technology stack entirely, with Visual Editor library as the only new client-side dependency.
|
|
|
|
## Data Models and Schema Changes
|
|
|
|
### Existing Collections Analysis
|
|
The Directus instance has 26 custom collections including:
|
|
- **projects** - Project management with status, priority, ownership
|
|
- **tasks** - Task management with progress tracking, assignments
|
|
- **subtasks** - Hierarchical task breakdown
|
|
- **task_dependencies** - Inter-task relationships
|
|
- **ai_prompts** - Mature prompt management (164+ tools)
|
|
|
|
Current data includes 3 projects, 2 tasks, 11 tags, and prompt templates.
|
|
|
|
### Schema Integration Strategy
|
|
|
|
**Minimal Additive Changes:**
|
|
```sql
|
|
-- Extend existing tasks table
|
|
ALTER TABLE tasks ADD COLUMN task_master_id VARCHAR(255);
|
|
ALTER TABLE tasks ADD COLUMN external_refs JSON;
|
|
ALTER TABLE tasks ADD COLUMN ai_context JSON;
|
|
|
|
-- Extend existing projects table
|
|
ALTER TABLE projects ADD COLUMN repository_url VARCHAR(255);
|
|
ALTER TABLE projects ADD COLUMN bmad_workflow_type VARCHAR(50);
|
|
ALTER TABLE projects ADD COLUMN task_master_project_path VARCHAR(255);
|
|
```
|
|
|
|
**Backward Compatibility:**
|
|
- All existing data preserved
|
|
- Current MCP tools continue unchanged
|
|
- Zero breaking changes
|
|
|
|
