ZhuLong: Execution-Grounded LLM Agent for EDA Scripting with Offline API Self-Exploration
ZhuLong is presented, an execution-grounded LLM coding agent for PyAether and SKILL that combines API retrieval, documentation inspection, and sandbox execution via unified MCP tools, augmented by an offline API self-exploration mechanism that infers undocumented API behaviors through counterfactual experimentation.
