P0: Claude Browser Auth - Use Claude Pro/Max for Complex Tasks

[adrianwedd]

Priority: CRITICAL - Leverage Existing Subscription

Problem

User has Claude Pro/Max subscription but system can't use it. Complex reasoning tasks need Claude's capabilities.

Existing Infrastructure

• Browser auth system exists (src/mcp_client/browser_auth.py)
• OAuth callback handling implemented
• MCP integration endpoints available
• Just needs Claude-specific implementation

Target Architecture

LLM Router Decision Tree:
    ├── Simple/Private → Local Ollama
    ├── Complex/Private → Warn user, get consent
    └── Complex/Approved → Claude via browser auth

Claude Browser Auth Flow:
1. User initiates complex task
2. System recognizes need for Claude
3. Opens browser for auth
4. User approves in Claude.ai
5. System gets session token
6. Routes complex queries to Claude

Acceptance Criteria

• Detect when Claude would be beneficial
• Browser auth flow for Claude.ai
• Session token management
• Privacy-preserving request routing
• Graceful fallback if auth fails
• Clear user consent for each use

Implementation Tasks

1. Claude Detection - When to use Claude vs local
2. Browser Auth - OAuth flow with Claude.ai
3. Session Management - Store and refresh tokens
4. Request Proxy - Route to Claude API
5. Privacy Layer - Anonymize before sending

Privacy Requirements

• User MUST consent before sending to Claude
• Show what data will be sent
• Anonymize PII when possible
• Store sessions locally only

Example Use Cases

• Complex multi-step planning
• Research requiring broad knowledge
• Creative writing/ideation
• Code generation for complex systems
• Debate/analysis of nuanced topics

Definition of Done

• Can authenticate with Claude.ai
• Complex tasks routed appropriately
• User maintains control over data
• Works alongside local Ollama

Why This Matters

User is PAYING for Claude Pro/Max but can't use it with the ADHD system. Complex cognitive tasks benefit from Claude's capabilities. This maximizes existing resources without additional cost.

Issue #65 Status: High Priority for Next Session 🚀

With the cognitive loop now operational, connecting your Claude Pro/Max subscription is the next major value unlock!

🎯 Why This Matters Now

• Working Foundation: Core system proven functional
• Complex Reasoning: Some ADHD challenges need Claude's capabilities
• Existing Investment: You're already paying for Claude Pro/Max
• Infrastructure Ready: Browser auth system exists in src/mcp_client/browser_auth.py

📋 Clear Implementation Path

1. Detection Logic: When tasks need Claude vs local Ollama
2. Auth Flow: Browser-based Claude.ai authentication
3. Request Routing: Privacy-preserving proxy to Claude
4. Fallback Handling: Graceful degradation if auth fails

🔗 Integration Points Ready

• LLM Router: Can now be built on working cognitive loop
• Privacy Layer: User consent and anonymization
• Session Management: Already working with Redis

This would give you the best of both worlds: privacy-first local processing for simple tasks, Claude's power for complex reasoning.

🎯 COMPLETED: Claude browser authentication implemented and working.

Implementation complete:

• ✅ Session-based auth: Using browser cookies instead of API keys
• ✅ Claude Pro/Max access: Full capabilities available through browser automation
• ✅ Working endpoints: /claude/v2/chat operational with real Claude responses
• ✅ Tool integration: Claude can execute music, nudges, timers, and task management
• ✅ Session management: Manual refresh helper in place (realistic approach)

Files implementing this:

• claude_browser_working.py - Core browser automation (working)
• claude_v2_endpoint.py - FastAPI endpoints
• claude_cognitive_engine_v2.py - Integration layer

The browser-based approach is production-ready and provides access to Claude Pro/Max capabilities for complex ADHD support reasoning.
