  • ralph-loop: Iterative, self-referential agent execution loops for complex refactoring.
  • orchestrate: Fan-out to parallel cloud agents with planner, worker, and verifier roles.
  • continual-learning: Transcript-driven updates to repo-level AGENTS.md memory files.
  • cli-for-agent: Design patterns and harnesses for agent-reliable CLI tools.
