Cursor has detailed the system architecture of its production-ready coding agent, highlighting key components like its Composer model and a router for selecting the optimal LLM for tasks. The agent utilizes a tool harness with over ten functions for code manipulation and execution, alongside a context retrieval system to manage large codebases. An orchestrator manages the iterative loop of reasoning and tool execution, with all operations secured within a sandboxed environment to prevent host machine compromise. AI
