Composio’s SWE agent advances open-source on SweBench with a 48.6% score using LangGraph and LangSmith

Composio has launched SWE-Kit, an open-source headless IDE with AI-native coding toolkits for AI agents. The platform features a Language Server Protocol (LSP) for code intelligence and a development container for secure code execution. It also includes comprehensive coding tools like CodeAnalysis, Shell tools, File management, and Git tools. SWE-Kit was tested on the SWE Bench, which evaluates the effectiveness of coding agents on real-world software engineering tasks. The platform uses specialized agents with distinct toolsets focused on specific tasks, improving performance by allowing each agent to focus on a well-defined task. Effective state management is crucial for reliability and predictability when building complex multi-agent systems, which SWE-Kit ensures through its sophisticated state management system.
