Telegram webhook receives all messages\n2. Command routing checks message content and directs to appropriate handler\n3. Article summarization: URL → HTTP fetch → HTML parsing → AI summary → Response\n4. Image generation: Prompt processing → AI handling → Response notification\n\n**Note:** Image generation currently returns text confirmation instead of actual images. Consider integrating with Stability AI or similar services for real image generation."
