Overview

• Environment Isolation - Like Conda for LLMs. Create separate environments to experiment with Claude, Codex, Antigravity, Copilot, or OpenCode settings without breaking your primary setup
• Cross-LLM Learning - Share context and learnings between different LLM providers (Claude, Codex, Antigravity, Copilot, and OpenCode)
• RAG (Without The Rot) For Your Code - Track things like repeated fixes the LLM forgets, including when you have to tell it the same thing 6 or 7 times in one session and it still doesn't understand, how you describe a feature and where that code lives, and file change summaries with commits, then only provide what’s useful at call time to prevent context rot.
• Few Shot Prompting - Get Antigravity or codex to code like Claude for code that has been done before with few shot prompting... Making them up to 20% better (research paper and eval data coming soon.)
• Rule Enforcement - Define and enforce coding standards like test coverage, cyclomatic complexity, logging practices, and more. LLMs fix their errors before code can be pushed or before the tech debt get astronomical.
• Token Savings - Learn your codebase and how you describe it, providing LLMs with smart file hints to reduce token usage and costs
• Rule Files (vc.rules.md) - Create and manage VibeRails rule files that gate every commit with WARN/COMMIT/STOP enforcement
• Web Terminal - Launch CLIs directly in the browser with xterm.js. Select base CLIs (Claude, Codex, Antigravity, Copilot, OpenCode, GLM
