The complexity of an agent may range from something relatively simple to whatever level of complexity you want. So your projet sounds doable but you'll have to run some exploration to get proper answers. Regarding reliability, quality and security, it is as important to learn how to observe an agent system than learning how to implement an agent system. An agent/LLM-based solution is proven to work only if you observe that it actually works, experiments, tests and monitoring are not optional like eg in web development. As for security concerns, you'd want to take a look at the OWASP top 10 for LLMs: https://owasp.org/www-project-top-10-for-large-language-mode... LLMs/agents indeed have their own new set of vulnerabilities.
