## Quick Start

```bash theme={null}
# 1) Create a new app
kernel create

# 2) Login
kernel login

# 3) Deploy your app
kernel deploy index.ts

# 4) Invoke your app
kernel invoke my-app action-name --payload '{"key":"value"}'
```

## Global Flags

* `--version`, `-v` - Print the CLI version
* `--no-color` - Disable color output
* `--log-level <level>` - Set the log level (trace, debug, info, warn, error, fatal, print)
* `--project <id-or-name>` - Scope the request to a specific [project](/reference/cli/projects) (also reads the `KERNEL_PROJECT` env var)

## JSON Output

Many commands support `--output json` (or `-o json`) for machine-readable output, useful for scripting and automation:

```bash theme={null}
# Get browser session as JSON
kernel browsers create -o json

# List apps as JSON array
kernel app list -o json

# Deploy with JSONL streaming (one JSON object per line)
kernel deploy index.ts -o json
```

See individual command documentation for JSON output availability.

## Skills

The Kernel CLI has a companion [skills file](https://github.com/kernel/skills/blob/main/plugins/kernel-cli/skills/kernel-cli/SKILL.md) that AI coding agents (Cursor, Claude, Windsurf, etc.) can use to learn the CLI's commands and capabilities. Copy the prompt from the [homepage](/) or point your agent directly at the skill file to get started.
