+# Stock Prices Module Implementation Plan
+
+Command to reread guidelines: Read /home/philkunz/.claude/CLAUDE.md
+
+## Overview
+Implementation of a stocks module for fetching current stock prices using various APIs, starting with Yahoo Finance API.
+
+## Phase 1: Yahoo Finance Implementation
+
+### 1.1 Research & Documentation
+- [ ] Research Yahoo Finance API endpoints (no official API, using public endpoints)
+- [ ] Document available data fields and formats
+- [ ] Identify rate limits and restrictions
+- [ ] Test endpoints manually with curl
+
+### 1.2 Module Structure
+```
+ts/
+├── index.ts                    # Main exports
+├── plugins.ts                  # External dependencies
+└── stocks/
+    ├── index.ts                # Stocks module exports
+    ├── classes.stockservice.ts # Main StockPriceService class
+    ├── interfaces/
+    │   ├── stockprice.ts      # IStockPrice interface
+    │   └── provider.ts        # IStockProvider interface
+    └── providers/
+        └── provider.yahoo.ts   # Yahoo Finance implementation
+```
+
+### 1.3 Core Interfaces
+```typescript
+// IStockPrice - Standardized stock price data
+interface IStockPrice {
+  ticker: string;
+  price: number;
+  currency: string;
+  change: number;
+  changePercent: number;
+  timestamp: Date;
+  provider: string;
+}
+
+// IStockProvider - Provider implementation contract
+interface IStockProvider {
+  name: string;
+  fetchPrice(ticker: string): Promise<IStockPrice>;
+  fetchPrices(tickers: string[]): Promise<IStockPrice[]>;
+  isAvailable(): Promise<boolean>;
+}
+```
+
+### 1.4 Yahoo Finance Provider Implementation
+- [ ] Create YahooFinanceProvider class
+- [ ] Implement HTTP requests to Yahoo Finance endpoints
+- [ ] Parse response data into IStockPrice format
+- [ ] Handle errors and edge cases
+- [ ] Add request throttling/rate limiting
+
+### 1.5 Main Service Class
+- [ ] Create StockPriceService class
+- [ ] Integrate Yahoo provider
+- [ ] Add method for single ticker lookup
+- [ ] Add method for batch ticker lookup
+- [ ] Implement error handling with graceful degradation
+
+## Phase 2: Core Features
+
+### 2.1 Service Architecture
+- [ ] Create extensible provider architecture
+- [ ] Design provider interface for future additions
+- [ ] Implement provider registration system
+
+## Phase 3: Advanced Features
+
+### 3.1 Caching System
+- [ ] Design cache interface
+- [ ] Implement in-memory cache with TTL
+- [ ] Add cache invalidation logic
+- [ ] Make cache configurable per ticker
+
+### 3.2 Configuration
+- [ ] Environment variable support for API keys
+- [ ] Provider configuration (enabled/disabled, priority)
+- [ ] Cache configuration (TTL, max entries)
+- [ ] Request timeout configuration
+
+### 3.3 Error Handling
+- [ ] Define custom error types
+- [ ] Implement retry logic with exponential backoff
+- [ ] Add circuit breaker pattern for failing providers
+- [ ] Comprehensive error logging
+
+## Phase 4: Testing
+
+### 4.1 Unit Tests
+- [ ] Test each provider independently
+- [ ] Mock HTTP requests for predictable testing
+- [ ] Test error scenarios
+- [ ] Test data transformation logic
+
+### 4.2 Integration Tests
+- [ ] Test with real API calls (rate limit aware)
+- [ ] Test provider fallback scenarios
+- [ ] Test batch operations
+- [ ] Test cache behavior
+
+### 4.3 Performance Tests
+- [ ] Measure response times
+- [ ] Test concurrent request handling
+- [ ] Validate cache effectiveness
+
+## Implementation Order
+
+1. **Week 1: Yahoo Finance Provider**
+   - Research and test Yahoo endpoints
+   - Implement basic provider and service
+   - Create core interfaces
+   - Basic error handling
+
+2. **Week 2: Additional Providers**
+   - Implement Alpha Vantage provider
+   - Implement IEX Cloud provider
+   - Add provider fallback logic
+
+3. **Week 3: Advanced Features**
+   - Implement caching system
+   - Add configuration management
+   - Enhance error handling
+
+4. **Week 4: Testing & Documentation**
+   - Write comprehensive tests
+   - Create usage documentation
+   - Performance optimization
+
+## Dependencies
+
+### Required
+- `@push.rocks/smartrequest` - HTTP requests
+- `@push.rocks/smartpromise` - Promise utilities
+- `@push.rocks/smartlog` - Logging
+
+### Development
+- `@git.zone/tstest` - Testing framework
+- `@git.zone/tsrun` - TypeScript execution
+
+## API Endpoints Research
+
+### Yahoo Finance
+- Base URL: `https://query1.finance.yahoo.com/v8/finance/chart/{ticker}`
+- No authentication required
+- Returns JSON with price data
+- Rate limits unknown (need to test)
+
+### Alpha Vantage
+- Base URL: `https://www.alphavantage.co/query`
+- Requires API key (free tier available)
+- 5 requests per minute, 500 requests per day (free)
+- Good documentation
+
+### IEX Cloud
+- Base URL: `https://cloud.iexapis.com/stable`
+- Requires authentication token
+- Free tier: 50,000 messages/month
+- Sandbox environment available
+
+## Success Criteria
+
+1. Can fetch current stock prices for any valid ticker
+2. Graceful fallback between providers
+3. Response time < 1 second for cached data
+4. Response time < 3 seconds for fresh data
+5. 99% uptime with at least one provider
+6. Comprehensive test coverage (>80%)
+
+## Notes
+
+- Start with Yahoo Finance as it requires no authentication
+- Implement proper TypeScript types for all data structures
+- Follow the project's coding standards (prefix interfaces with 'I')
+- Use plugins.ts for all external dependencies
+- Keep filenames lowercase
+- Write tests using @git.zone/tstest with smartexpect syntax
