feat: Tree-of-Thoughts Visual Orchestration System - Foundation & PRD

[codegen-sh]

🚀 Tree-of-Thoughts Visual Orchestration System - Phase 0 Complete

📋 Overview

This PR establishes the foundation for the Tree-of-Thoughts Visual Orchestration System, a revolutionary visual workflow editor that combines intelligent multi-path exploration with context-aware AI assistance.

✅ What's Included

1️⃣ Vibe-Coding-Playbook Rules Integration

Establishes comprehensive coding standards for all development:

• ✅ TypeScript best practices (no any, branded types, strict mode)
• ✅ React conventions (functional components, hooks, composition)
• ✅ Testing requirements (>80% coverage, React Testing Library)
• ✅ Security guidelines (input validation, parameterized queries)
• ✅ Performance optimization (lazy loading, code splitting)
• ✅ Verification protocol (typecheck, lint, test before commit)

2️⃣ Comprehensive Product Requirements Document

File: frontend/docs/TREE_OF_THOUGHTS_PRD.md

Complete 14-section PRD (800+ lines) following Mercury Spec Ops template:

• Scalability: 10K concurrent executions, 1M+ workflows per org
• Reliability: 99.9% uptime SLA, zero data loss

Timeline

• 12 weeks total across 6 phases
• Phase 1-2: Foundation + Visual Editor (Weeks 1-4)
• Phase 3-4: ToT Engine + AI Chat (Weeks 5-8)
• Phase 5-6: Templates + Polish (Weeks 9-12)

Success Criteria

• Launch: All P0 features, <3 critical bugs, >90% test coverage
• 6-Month: 5,000+ users, 500+ weekly workflows, NPS >40, 99.9% uptime

🎯 What's Next

This PR sets the foundation. Next steps:

Phase 1: Visual Flow Editor (Weeks 3-4)

1. Install @xyflow/react package
2. Create VisualFlowEditor component
3. Implement node types (Start, Sequential, Parallel, Conditional, End)
4. Build draggable node palette
5. Add real-time validation

Phase 2: Tree-of-Thoughts Engine (Weeks 5-6)

1. Implement thought generation (2-10 branches)
2. Build evaluation strategies (LLM, rules, historical)
3. Add pruning algorithms (beam search, best-first)
4. Integrate with existing ChainExecutor
5. Create thought tree visualization

Phase 3: Context-Aware AI Chat (Weeks 7-8)

1. Build Context Aggregation Service
2. Create AIChatBubble component
3. Implement slash commands
4. Add Quick Actions
5. Real-time context updates

🎨 Key Design Decisions

1. ReactFlow over D3.js: Built-in features, faster development, proven at scale
2. Zustand over Redux: 10x simpler, better TypeScript support
3. PostgreSQL + Redis: Relational structure + high-speed cache
4. BullMQ: Job priorities, retries, scheduling, dashboard

✅ Validation

• Vibe-coding-playbook rules integrated
• PRD complete with all 14 sections
• Technical architecture defined
• Timeline and milestones established
• Success criteria documented
• Risks identified with mitigation strategies
• All commits follow standards
• TruffleHog scan passed (no secrets)

📊 Metrics

• PRD: 800+ lines, 14 sections
• Rules: 130 lines of coding standards
• Total Documentation: ~1,000 lines
• Estimated Implementation: 12 weeks
