What's New in v0.4.0

4 New Providers (12 Total)

Mysti now supports 12 AI providers — added OpenCode, Qwen Code, Ollama, and LocalAI alongside Claude Code, Codex, Gemini, GitHub Copilot, Cline, Cursor, OpenClaw, and Manus. Run local models with Ollama/LocalAI or use cloud providers like OpenCode and Qwen Code. Each provider has its own authentic logo in the UI.

Qwen Code

Alibaba's AI coding CLI with deep reasoning capabilities. Uses the same streaming protocol as Claude Code for seamless integration. Supports Qwen3 Coder models with plan, auto-edit, and yolo approval modes.

OpenCode

Multi-backend coding agent supporting Anthropic, OpenAI, Google, and Groq through a single CLI. Uses your configured default model — no lock-in to specific providers.

Local AI Support

Run AI models locally with Ollama and LocalAI — no cloud subscription needed. Full privacy, zero latency, complete control over your models.

Stability & Testing

18 stability fixes across brainstorm mode and @-mention tagging — silence-based timeouts, auth pre-checks, convergence guards, mention limits, and retry cleanup. Plus 360 automated tests via vitest ensuring reliability across all features.

Bug Fixes

Windows: Fixed spawn EINVAL error with auto shell mode (#14)
Codex: Brainstorm now respects mysti.codexPath setting (#26)

Brainstorm Mode

Want a second opinion? Enable Brainstorm Mode and let two AI agents tackle your problem together. Choose any 2 of 12 agents from the settings panel.

5 Collaboration Strategies

Strategy	Roles	Best For
Quick	Direct synthesis	Simple tasks, fast answers
Debate	Critic vs Defender	Architecture decisions, trade-offs
Red-Team	Proposer vs Challenger	Security reviews, edge case discovery
Perspectives	Risk Analyst vs Innovator	Greenfield design, technology selection
Delphi	Facilitator vs Refiner	Complex problems, reaching consensus

Why Two AIs Beat One

Claude Code (Anthropic), Codex (OpenAI), Gemini (Google), GitHub Copilot, Cline, Cursor, OpenClaw, OpenCode, Qwen Code (Alibaba), Ollama, and LocalAI 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.

Choose Your Team

Configure which two agents collaborate in the Settings Panel:

Combination	Best For
Claude + Codex	Deep analysis meets rapid iteration
Claude + Gemini	Thorough reasoning with fast validation
Claude + Copilot	Compare native Claude vs Copilot's multi-model approach
Cursor + Gemini	Multi-model flexibility with Google integration
OpenClaw + Claude	WebSocket streaming with deep reasoning
Qwen + Claude	Compare Alibaba and Anthropic reasoning
OpenCode + Gemini	Multi-backend flexibility with Google speed
Ollama + Claude	Local privacy meets cloud intelligence

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

Full Compaction documentation
