## 📢 **Latest Updates**

- **OpenClaw Integration (Beta):** OpenClaw is now successfully installed on our **Mac Mini** host! We are currently working on a deep integration between **CVC** and **OpenClaw** to enable seamless cognitive versioning for all OpenClaw agents.
- **Enhanced Agent Tools:** v1.8.50 includes updated prompt instructions for the built-in agent to better handle high-volume token responses and complex JSON structures.

## 🚀 CVC 2.0: The Agentic Era

CVC has evolved from a simple context backup tool into a **Cognitive Version Control** system designed for Autonomous Agent Orchestration.

- **Semantic Merging**: Resolve cognitive collisions between branches using ChromaDB vector embeddings. Merges insights, not just logs.
- **Quantum Branching (Tree of Thoughts)**: Race multiple LangGraph agents down parallel reality branches simultaneously. Merge the winning solution and archive failed attempts as learning data.
- **Micro-Rollbacks**: Rewind execution histories at the thought-level or tool-call level using the new THOUGHT_STEP and TOOL_CALL commit states.
- **Context Distillation Checkpoints**: Compress massive timelines dynamically to save LLM tokens while retaining semantic searchability.
- **Multi-Agent Telepathy**: Pack a branch's exact cognitive state into a portable .cvcpack and beam it over the MCP protocol to another machine.
- **Claude-style Parallel Tool Execution**: The CVC CLI Agent now supports running multiple destructive/write operations simultaneously via dynamic telepathy branching.


## 💥 **The Problem**

<br>

### Your AI coding agent is brilliant — for about 20 minutes.

Then it **forgets** what it already fixed, **contradicts** its own plan,  
and **loops** on the same error for eternity.

<br>

### ***Sound familiar?***

## ✨ **The Solution: CVC**

Give AI agents what they've never had: **memory that actually works.**

<!-- ═══════════════════════════════════════════════════════════════════════ -->

## 🎯 **Why CVC?**

<div align="center">

**CVC** is Git for the AI's brain.  
Instead of versioning source code, it versions the agent's **entire cognitive state** — every thought, every decision, every conversation turn — as an immutable, cryptographic **Merkle DAG**.

## ❓ **FAQ**

<details>
<summary><b>What is CVC?</b></summary>

<br>

CVC (Cognitive Version Control) is Git for AI agent context. It versions the agent''s entire cognitive state as an immutable Merkle DAG, enabling time-travel, branching, and merging for AI conversations.

</details>

<details>
<summary><b>How is CVC different from Claude Code or Cursor?</b></summary>

<br>

CVC adds: ⏪ Time-travel • 🌿 Branching • 🔍 Semantic search • 🔀 Context merging • 💾 Auto-checkpoint • 🔄 Crash recovery • 🤖 Multi-provider support (5 vs 1)

</details>

<details>
<summary><b>Does CVC work with my existing AI tools?</b></summary>

<br>

**Yes!** CVC works in two modes:  
1. **Agent mode** — built-in AI assistant  
2. **Proxy mode** — transparent proxy for Claude Code, Aider, Cursor, VS Code, Windsurf, Continue, Cline, LangChain, CrewAI, AutoGen, and more

</details>

<details>
<summary><b>Is my data sent to the cloud?</b></summary>

<br>

**No.** Everything stays local in `.cvc/`. CVC has:  
🔒 No telemetry • 🔒 No cloud sync • 🔒 No data collection  
Your agent''s thoughts are **yours**.

</details>

<details>
<summary><b>How much does it cost?</b></summary>

<br>

**CVC is free and open-source (MIT license).** You only pay for LLM API calls (Anthropic/OpenAI/Google), and CVC makes them **~90% cheaper** via prompt caching and **58.1% less context** via branching. Use Ollama for 100% free local operation.

</details>

<details>
<summary><b>Can I use CVC offline?</b></summary>

<br>

**Yes!** Use Ollama with local models like `qwen2.5-coder:7b`, `deepseek-r1:8b`, etc. 100% local, no API key needed.

</details>

<details>
<summary><b>What providers are supported?</b></summary>

<br>

- 🟣 **Anthropic** (Claude Opus 4.6, Sonnet 4.5, Haiku 4.5)  
- 🟢 **OpenAI** (GPT-5.2, GPT-5.2-Codex, GPT-5-mini)  
- 🔵 **Google** (Gemini 3 Pro/Flash Preview, Gemini 2.5 Pro/Flash — with thinking level control)  
- ⚪ **Ollama** (Qwen, DeepSeek, Devstral, etc.)  
- 🟤 **LM Studio** (any locally loaded model — OpenAI-compatible)

</details>

<details>
<summary><b>Is there a GUI?</b></summary>

<br>

Not yet! But coming soon:  
🎨 **VS Code extension** (Q2 2026)  
🌐 **Web UI** (Q2 2026)  

For now, use the beautiful terminal UI with Rich formatting.

</details>

<details>
<summary><b>Can I use CVC in production?</b></summary>

<br>

**Yes!** CVC is production-ready (v1.8.50) with crash-resistant local storage, used by solo developers, teams, and enterprises.

</details>
