## Overview
VT Code is an open-source terminal coding agent built in Rust. Explore a
codebase, plan changes, run tools, and review edits in the interactive TUI, or
run `vtcode exec` headless. You pick the model and permissions; the runtime
handles context, tools, and execution policy, and you review every change
before it lands.
- **Plan and review:** read-only planning mode, then inspect edits in turn diffs.
- **Sustain long sessions:** project instructions, context compaction, resumption, execution logs.
- **Control execution:** command policy and sandboxing at the boundary.
- **Choose your stack:** hosted or local models, plus MCP servers, Agent Skills, and Plugins.

<em>Plan, run, and review coding work from your terminal.</em>

> [!NOTE]
> **Status:** Active development; some automation flows are experimental.
## Quick start
### 1. Install
```bash
The installer also sets up `ripgrep` and `ast-grep` on macOS/Linux. Or use
Homebrew or Cargo:
```bash
brew trust vinhnx/tap
brew install vinhnx/tap/vtcode
# Or install with Rust
cargo install vtcode
```
See the [installation guide](./docs/installation/README.md) for prerequisites,
other methods, and the installer script you can review before running.
> [!NOTE]
> Windows artifacts are best-effort and may lag behind macOS/Linux.
### 2. Configure your project
Open your project, initialize its configuration and instructions, then add
credentials for your chosen provider. For example, with OpenAI:
```bash
cd path/to/your/project
vtcode init # scaffolds config + AGENTS.md; review before committing
vtcode secret add openai # stores an OpenAI API key in your OS keyring
```
Replace `openai` with your supported provider. Credentials can also come from
environment variables or a workspace `.env`; `vtcode login` handles supported
login flows. See [Getting started](./docs/user-guide/getting-started.md) and
[Provider guides](./docs/providers/PROVIDER_GUIDES.md).
> [!NOTE]
> ChatGPT OAuth reuses the Codex CLI's public client identity through an
> unofficial compatibility flow; prefer your own OpenAI API key. GitHub
> Copilot uses the official `copilot` CLI. See
> [OAuth authentication](./docs/guides/oauth-authentication.md).
> [!CAUTION]
> Never commit API keys or put them in `vtcode.toml`.
### 3. Start an interactive session
```bash
vtcode # open the interactive TUI in your project
```
Start with a focused request, such as “Explain how this project handles
authentication,” then review the diff and test results before committing. For
automation and session commands, see [Workflows](#workflows).
## Workflows
### Interactive work
Use `vtcode` to explore a codebase, plan a change, and implement it in the TUI.
For larger tasks, start with [read-only planning](./docs/guides/planning-workflow.md)
and review [turn diffs](./docs/development/diff-preview.md) before committing.
See the [interactive guide](./docs/user-guide/interactive-mode.md) for controls.
### Headless automation
Use `ask` for a tool-free answer and `exec` for a tool-enabled coding task:
```bash
vtcode ask "explain Rc vs Arc" # one-shot answer, no session, no tools
vtcode exec "refactor main.rs" # headless task with the full tool loop
vtcode review # agent review of uncommitted changes
```
`exec` needs autonomous execution enabled in `[automation.full_auto]` plus
`full_auto` workspace trust. In a terminal, an untrusted workspace prompts for
trust; in CI or another non-TTY environment, grant trust beforehand or set
`VTCODE_TRUST_WORKSPACE=full-auto`; otherwise non-TTY runs fail rather than
prompt. Full-auto's tool allow-list, explicit denies, and execution policy still
apply. See [exec mode](./docs/user-guide/exec-mode.md) for trust and output
options and [full automation](./docs/guides/full-automation.md) for
configuration.
For repeatable, environment-checked results, use the
[eval framework](./docs/guides/eval.md): a completion message alone is not
verification.
### Scheduled tasks
For recurring work, use [scheduled tasks](./docs/user-guide/scheduled-tasks.md):
durable prompt jobs on the same exec runtime:
```bash
# Weekly dependency audit (Mondays 09:00)
vtcode schedule create --name "weekly-dep-audit" \
--cron "0 9 * * 1" \
--prompt "Check for outdated dependencies and report known vulnerabilities"
```
### Session management
```bash
# Resume the most recent interactive session
vtcode continue
# Continue the last headless run with a follow-up prompt
vtcode exec resume --last "continue the refactor"
# Inspect the execution log
vtcode trajectory
```
Use `vtcode continue --session-id <id>` to fork an earlier session.
See `vtcode --help` or the [command reference](./docs/user-guide/commands.md)
for all commands and flags.
### Optional integrations
Enable these only when you need them; none are required for the quick start.
- **Tools and extensions:** [MCP servers](./docs/guides/mcp-integration.md),
[Agent Skills](./docs/skills/SKILLS_GUIDE.md), and
[Plugins](./docs/guides/agent-plugins.md).
- **Editors:** [ACP with Zed](./docs/guides/zed-acp.md).
- **Cross-thread memory:** [Memcode MCP](./docs/guides/memcode-mcp.md) carries
context between tasks; see the
[write-up](https://memcode.in/blogs/vt-code-memory-across-threads).
- **Browser editing:** [WebMCP](./docs/user-guide/webmcp.md) pairs the TUI with
an authenticated browser editor:
```bash
/webmcp pair <origin> # inside the TUI
```
The hosted app at [vtcode.vinhnx.chatgpt.site](https://vtcode.vinhnx.chatgpt.site/)
([mirror](https://vinhnx.github.io/VTCode/)) uses this authenticated,
workspace-scoped bridge. Setup and deployment:

Requires Rust 1.98.1+ (edition 2024) and `cargo-nextest` for tests:
```bash
git clone https://github.com/vinhnx/VTCode.git
cd VTCode
./scripts/run-debug.sh # build and launch a debug binary
./scripts/check-dev.sh # fast gate: clippy, fmt, check
cargo nextest run # tests (requires cargo-nextest)
```
CI sets `RUSTFLAGS="-D warnings"` and builds with `--locked`; match locally
with `RUSTFLAGS="-D warnings" cargo check --locked`. Setup and checks:
