What is VT Code?

VT Code is a Rust coding agent built for long-running autonomous workflows, with OS-native sandboxing, multi-provider LLM support, open protocols, and extensible Skills.

Features

• Agent runtime - Interactive TUI, slash commands, streaming, ask/exec CLI, session resume
• Coding tools - Safe file ops, ripgrep search, fuzzy discovery, code intelligence, project indexing, terminal execution
• Extensibility - Agent Skills, MCP client/server, lifecycle hooks, subagents, custom providers, Zed ACP, VS Code, Claude Code
• Model providers - 21+ LLM providers: Anthropic, OpenAI, Gemini, OpenRouter, Ollama, LM Studio, and more
• Safety - Restricted shell sandbox, tool guardrails, subprocess isolation, full audit logging
• Protocols - Open Responses, Agent2Agent (A2A), ATIF, Anthropic Messages API
• Loop engineering - Worktree isolation for parallel agents, propose/verify sub-agent separation, durable loop state, cost guardrails

Quick start

curl -fsSL https://raw.githubusercontent.com/vinhnx/vtcode/main/scripts/install.sh | bash
vtcode init
vtcode

1. Install - one-liner for macOS/Linux (also installs ripgrep + ast-grep)
2. Init - scaffolds vtcode.toml, .vtcode/, and AGENTS.md in your project
3. Launch - interactive TUI with streaming, tools, and slash commands

Common commands

vtcode                         # interactive TUI
vtcode init                    # scaffold project config + AGENTS.md
vtcode ask "explain Rc vs Arc" # one-shot question
vtcode exec "refactor main.rs" # headless task with full tool access
vtcode review                  # review uncommitted changes
vtcode update                  # self-update

Documentation

• Interactive TUI - Primary agents, slash commands (/model, /review, /mcp, /skills, /theme, /compact)
• Full automation - --full-auto CLI, plan-build-evaluate harness, subagents, scheduled tasks
• Providers - Setup guides for all 21 providers
• Configuration - vtcode.toml, tool config, lifecycle hooks
• Agent Skills - Creating, loading, and sharing skills
• MCP Integration - Client and server modes
• Editor guides - Zed ACP, VS Code, Claude Code
• Safety - Shell sandbox, security hardening, threat model
• Protocols - Open Responses, ATIF, A2A, Anthropic Messages API
• Loop engineering - Worktree isolation, propose/verify, loop state, cost guardrails

I'd love to have you, bug reports, docs, features, ideas, all welcome. Start with issues or good first issues. AI agents see AGENTS.md. Humans see CONTRIBUTING.md.

                     

Support

VT Code is a labor of love built in my spare time. If it's helped you ship something or learn something, a sponsorship would mean the world.
