About this tool

Overview

RSIHub is an open-source framework for building agents that improve themselves through evaluator-driven learning. It emphasizes reproducible candidate lineage and controllable modification, allowing developers to track agent evolution and preserve evidence.

Key Capabilities

  • Evaluator-driven learning: Agents train and improve through evaluator feedback.
  • Reproducible candidate lineage: Records each modified candidate version for traceability.
  • Controllable modification: Limits what agents can modify via declared surface and editable_roots.
  • Multi-agent support: Supports codex, claude-code, aider, gemini-cli, mini-swe-agent, opencode, openhands, swe-agent, and others.
  • Workspace management: Creates new workspaces when initialization inputs change, avoiding unintended modifications.

Use Cases

  • Controlled agent modification
  • Reproducible agent lineage tracking
  • Self-evolving agent development
