AIG (AI-integrated Ground)
A web-based algorithm problem-solving platform powered by a LangGraph AI coding agent. The agent assists in real time with code writing, debugging, and hints, while its full execution flow is traceable per session through a Langfuse-style Trace viewer. A per-user harness system lets you customize the agent's behavior and prompts without touching the codebase.
