Large Language Model (LLM) agents are increasingly being used for code intelligence, automated reasoning, and software analysis. However, their effectiveness depends on their ability to perform deep, structured analysis across multiple programming languages. This workshop will introduce CLDK (CodeLLM DevKit), a powerful multilingual static and dynamic analysis framework designed to supercharge LLM-based coding agents. The demos will illustrate how CLDK enables fine-grained program understanding, reasoning, and transformation across diverse programming languages. We will demonstrate how CLDK can be integrated with LLM agents to enhance tasks such as code refactoring, automated debugging, test generation, and vulnerability detection. The workshop will feature interactive discussions, live demos, and hands-on exercises to help researchers and developers build next-generation AI- powered software agents.
