Release Notes: Vibe Check v2.1

Date: 2025-07-22

This is a major release that completely overhauls Vibe Check, transforming it from a simple feedback tool into a powerful meta-mentor for AI agents.

✨ New Features

• CPI Architecture: We've introduced the Chain Pattern Interrupt (CPI) architecture, a groundbreaking new approach that allows Vibe Check to act as a meta-mentor for your AI agents. This helps to prevent "Reasoning Lock-In" and improves the overall quality of your agent's output.
• Multi-Provider Support: You can now use Vibe Check with Gemini, OpenAI, and OpenRouter. This gives you the flexibility to choose the best model for your needs.
• Optional vibe_learn: The vibe_learn tool is now optional. You can disable it if you only need the core meta-mentor functionality of vibe_check.

🚀 Improvements

• Improved Prompts: The prompts used by the meta-mentor have been rewritten to be kinder and more focused on improving the agent's methodology.
• History Continuity: Vibe Check now has a memory! Previous interactions are fed back into the model, resulting in more coherent and context-aware conversations.
• Project Restructure: The entire project has been restructured to improve stability and make it easier to deploy in a production environment.
