-
-This file provides guidance to Claude Code (claude.ai/code) when working with code in this repository.
-
-## Common Commands
-
-### Development
-- `wrangler login` - Authenticate with Cloudflare
-- `wrangler publish` - Deploy the worker to Cloudflare Workers
-- `wrangler publish --env development` - Deploy to development environment
-- `wrangler publish --env production` - Deploy to production environment
-- `wrangler tail` - View real-time logs from the deployed worker
-- `wrangler secret put DEEPSEEK_API_KEY` - Set the DeepSeek API key
-- `wrangler secret put PROXY_KEY` - Set the proxy authentication key
-- `wrangler secret list` - List all configured secrets
-- `wrangler deployments list` - View deployment history
-
-### Testing
-- Health check: `curl https://your-worker.workers.dev/`
-- API test: `curl -X POST https://your-worker.workers.dev/chat -H "Authorization: Bearer YOUR_PROXY_KEY" -H "Content-Type: application/json" -d '{"model":"deepseek-chat","messages":[{"role":"user","content":"Hello"}]}'`
-
-## Architecture Overview
-
-This is a **Cloudflare Workers-based AI proxy service** that securely proxies requests to AI APIs (currently DeepSeek) without exposing API keys to client applications.
-
-### Core Components
-
-**Main Entry Point**: `worker.js` - Single file containing all proxy logic
-- Modular request validation system with separated concerns
-- Upstream API communication with timeout handling  
-- Error handling and logging
-- CORS and security headers
-- Streaming response support
-
-**Configuration**: `wrangler.toml` - Cloudflare Workers configuration
-- Worker name and entry point
-- Compatibility date
-- Environment-specific settings
-
-**Environment Variables** (stored as Cloudflare secrets):
-- `DEEPSEEK_API_KEY` (required) - DeepSeek API authentication
-- `PROXY_KEY` (optional but recommended) - Client authentication
-
-### Request Flow
-1. Client sends POST request to `/chat` endpoint
-2. Worker validates authentication via `PROXY_KEY`
-3. Worker validates request using modular validation functions:
-   - Content-Type validation (`validateContentType`)
-   - Content-Length validation (`validateContentLength`)  
-   - Request body validation (`validateRequestBody`)
-   - Message format validation (`validateMessages`)
-   - Individual message validation (`validateSingleMessage`)
-   - Model validation (`validateModel`)
-4. Worker forwards request to DeepSeek API with proper headers
-5. Worker streams response back to client with appropriate headers
-
-### Supported Models
-- `deepseek-chat` - General conversation model (DeepSeek-V3)
-- `deepseek-reasoner` - Complex reasoning model (DeepSeek-R1)
-
-### Configuration Constants (in worker.js)
-- `MAX_BODY_SIZE`: 1MB request limit
-- `REQUEST_TIMEOUT`: 30 second timeout
-- `VALIDATE_REQUEST_BODY`: Request validation toggle
-- `SUPPORTED_MODELS`: Array of valid model names
-
-### Security Features
-- API key isolation (stored server-side only)
-- Optional proxy authentication
-- Request size limits
-- Timeout protection
-- CORS headers for web integration
-- Security headers (XSS protection, content type validation)
-
-### Error Handling
-Standardized error responses with:
-- Descriptive error codes
-- Timestamps
-- Proper HTTP status codes
-- Detailed logging for debugging
-
-### Code Quality Features
-- **Low Cognitive Complexity**: Validation logic split into focused, single-responsibility functions
-- **Modular Design**: Each validation concern separated for better maintainability
-- **Error Isolation**: Specific error handling for different validation types
-- **Extensible Architecture**: Easy to add new validation rules or modify existing ones
-
-### Future Architecture
-The codebase is designed to support multiple AI providers. The current implementation focuses on DeepSeek but includes extensible patterns for adding OpenAI, Claude, and other providers in future versions.
