Mysti - Your AI Coding Team Working Together

Your AI Coding team for VSCode
7 AI providers — Claude Code, Codex, Gemini, Copilot, Cline, Cursor & OpenClaw — working solo or in teams
Wisdom of the crowd where the collective intelligence of several agents outperforms a single one.

What's New in v0.3.1

7 AI Providers

Mysti now supports 7 AI providers — added Cursor, OpenClaw, and Cline alongside Claude Code, Codex, Gemini, and GitHub Copilot. Switch between providers with one click or use @agent mentions to route tasks to specific AIs.

Autonomous Mode

Let the AI work independently with built-in safety controls. A three-level safety classifier (safe/caution/blocked) evaluates every operation, while a learning memory system adapts to your preferences over time. Learn more

@-Mention System

Type @claude, @gemini, or any agent name to route tasks directly. Chain agents for multi-perspective workflows: @claude Write a sort function, then @codex optimize it. Reference files with @filename.ts for instant context. Learn more

5 Brainstorm Collaboration Strategies

Brainstorm Mode now offers 5 strategies — Quick, Debate, Red-Team, Perspectives, and Delphi — each with role-based discussion and convergence detection. Learn more

Context Compaction

Smart conversation compaction prevents context overflow. Native /compact support for Claude Code, with client-side summarization for other providers. Learn more

Install in Seconds

From VS Code: Press Ctrl+P (Cmd+P on Mac), then paste:

ext install DeepMyst.mysti

Or install from the VS Code Marketplace

Choose Your AI

Mysti works with the AI coding tools you already have. No extra subscriptions needed.

Switch providers with one click. No lock-in.

Why Mysti?

See It In Action

Beautiful, modern chat interface with syntax highlighting, markdown support, and mermaid diagrams

Brainstorm Mode

Want a second opinion? Enable Brainstorm Mode and let two AI agents tackle your problem together. Choose any 2 of 7 agents from the settings panel.

5 Collaboration Strategies

Why Two AIs Beat One

Claude Code (Anthropic), Codex (OpenAI), Gemini (Google), GitHub Copilot, Cline, Cursor, and OpenClaw have different training, different strengths, and different blind spots. When any two work together:

• Each AI catches edge cases the other might miss
• Different perspectives lead to more robust solutions
• Together they debate, challenge each other, and synthesize the best solution

It's like having a senior dev and a tech lead review your code—except they actually discuss it first.

Convergence Detection

During discussions, Mysti tracks agent agreement and position stability. When auto-convergence is enabled, the discussion exits early once agents reach consensus — saving time without sacrificing quality.

Intelligent Plan Detection

When the AI presents multiple implementation approaches, Mysti automatically detects them and lets you choose your preferred path.

Requires at least 2 CLI tools installed. See Requirements.

Key Features

Autonomous Mode

Let the AI work independently with configurable safety controls:

• Safety Classifier: Three levels — safe (auto-approve), caution (mode-dependent), blocked (always deny)
• Three Safety Modes: Conservative, Balanced, Aggressive
• Learning Memory: Remembers your permission preferences and improves over time
• Continuation Modes: Goal-based or task-queue for extended autonomous sessions
• Audit Trail: Every autonomous decision is logged for review

Full Autonomous Mode documentation

@-Mention System

Route tasks to specific agents and reference files inline:

@claude Review this code for security issues
@src/auth.ts @gemini Suggest performance improvements for this file
@claude Write tests, then @codex optimize them

• File mentions: @filename adds transient context
• Agent mentions: @agent routes tasks to that provider
• Chaining: Later agents receive earlier agents' responses as context

Full @-Mention documentation

Context Compaction

Smart conversation management that prevents context overflow:

• Automatic: Triggers when token usage approaches the threshold (default 75%)
• Native support: Claude Code uses built-in /compact command
• Client-side: Other providers use intelligent message summarization
• Per-panel tracking: Each chat panel tracks usage independently

Mysti works with your existing subscriptions—no additional costs!

You only need one CLI to get started. Install any two to unlock Brainstorm Mode.

Quick Start

1. Install Mysti

Option A: Press Ctrl+P (Cmd+P on Mac), paste and run:

ext install DeepMyst.mysti

Option B: Install from VS Code Marketplace

2. Install a CLI Tool

# Claude Code (recommended)
npm install -g @anthropic-ai/claude-code
claude auth login

# Or GitHub Copilot CLI (access Claude, GPT-5, Gemini via GitHub)
npm install -g @github/copilot-cli
copilot  # then use /login command

# Or Gemini CLI
npm install -g @google/gemini-cli
gemini auth login

# Or Cursor
curl https://cursor.com/install -fsS | bash
agent login

# Or OpenClaw
npm install -g openclaw@latest && openclaw onboard --install-daemon
openclaw login

For Brainstorm Mode, install any two CLI tools.
