About
AgentCheck is a research workbench implementing the Reproduce-Intervene-Mitigate methodology for debugging LLM agents. It records agent-tool interactions over MCP, enables replay with controlled interventions to isolate issues, and tests fixes in a sandbox before production deployment. Designed for researchers and developers building reliable agent systems who need systematic debugging workflows beyond traditional logging.
