Developed and delivered a feature upgrade for the Comet Browser Assistant by introducing a dedicated system prompt within the asgeirtj/system_prompts_leaks repository. This enhancement improved user guidance and responsiveness in the Perplexity browser environment by leveraging AI development and natural language processing techniques. The system prompt was designed with modularity in mind, laying the foundation for future enhancements and adaptability. Work was implemented using Markdown to structure and document the prompt logic, with a focus on system design principles to ensure maintainability. The update addressed user assistance needs and contributed to a more robust and extensible browser assistant framework.
