Practical overview
When it fits
Use Mysti when a coding decision benefits from another agent’s perspective, when work needs a specialist-to-reviewer handoff, or when you want a structured multi-agent discussion inside VS Code.
Who it is for
- Developers who want to compare responses from multiple coding agents.
- VS Code users who want to assign work to one agent and have another review the result.
- Teams or individuals using connected tools and selected project context to inform coding work.
Documented uses
- Request separately attributed opinions from multiple agents, including concurrent read-only assignments.
- Sequence a specialist task and a follow-up review so the second assignment receives the first result.
- Use Brainstorm strategies to analyze a proposal and view individual reasoning alongside a synthesis.
- Bring selected Git changes and connected GitHub or Slack evidence into a Proactive inbox.
Requirements & limits
The repository identifies Mysti as open source under Apache-2.0. Its documentation labels version 2.0 as beta.
- The listed integrations include CLI agents, local model servers and a Mysti coordinator; provider setup requirements vary.
- The repository describes 16 provider adapters plus the Mysti coordinator.
- Connected apps and MCP servers are browsed and authorized through DeepMyst; catalog availability and tool permissions depend on the service and account.
- Cloud Proactive monitoring requires DeepMyst sign-in, a supported connection and an explicitly configured responsibility.
- Tour recordings show sample responses rather than live provider execution or performance benchmarks.
Check current requirements in the official documentation. Source-based guidance does not mean OpenViST has run or independently tested this project.
Request parallel opinions from Claude Code and Codex
Ask two tagged agents for independent opinions in a Mysti conversation.
Before you start
- Mysti in VS Code
- Claude Code and Codex configured as agents
Steps
Enter a prompt that explicitly tags both agents, such as
@claude @codex What are your opinions on adding a cache to this API?.Submit the prompt and compare the separately attributed answers in the conversation.
Expected outcome
Each agent has its own live card and attributed answer; independent read-only assignments run concurrently within the configured limit.
Guide limitations
- A failed participant remains visible; Mysti does not generate its answer or have the other agent impersonate it.
- The documented recordings use deterministic sample responses, not live provider runs or performance benchmarks.
Hand a completed design from one agent to another for review
Run a sequential assignment in which one agent's result becomes the next agent's review input.
Before you start
- Mysti in VS Code
- Claude Code and Codex configured as agents
Steps
Enter a prompt assigning the first task to Claude and the dependent review to Codex, for example:
@claude Design a retry policy, then @codex review it for edge cases.Submit the prompt and follow the progress cards to see the current step and next agent.
Expected outcome
Claude designs the policy, then Codex receives that result to review; progress cards show workflow progress.
Guide limitations
- A failed dependency blocks its dependent step.
- Work that may edit a shared workspace runs serially.

These projects document a common task and share a project role. This is a source-based comparison, not an execution benchmark or a guarantee of interchangeability.
| Project | Documented purpose | Platform | Access and requirements |
|---|---|---|---|
| Mysti | Request separately attributed opinions from multiple agents, including concurrent read-only assignments. | Desktop, Linux, macOS, Windows | The repository identifies Mysti as open source under Apache-2.0. Its documentation labels version 2.0 as beta. |
| Llmcode | Inspect a project's directory structure with `/tree`. | CLI | The documented setup requires an API key and supports an API base URL and model setting. The project is open source under Apache-2.0. |
| Klaat Code | Open a project directory for terminal-based coding assistance. | CLI, Server | The README provides a global npm installation command and documents browser sign-in with a KlaatAI account. It also identifies the repository as open source under Apache 2.0. |
