## First-Party Plugins

- **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.
- **Ecosystem:** Bundles ~20 SaaS integrations (GitHub, Gmail, Playwright, Salesforce, etc.).
