## Why kbot?

Most terminal AI agents lock you into one provider, one model, one way of working. kbot doesn't.

- **20 providers, zero lock-in** — Claude, GPT, Gemini, Grok, DeepSeek, Groq, Mistral, SambaNova, Cerebras, OpenRouter, and more. Switch with one command.
- **Runs fully offline** — Embedded llama.cpp, Ollama, LM Studio, or Jan. $0, fully private.
- **Learns your patterns** — Bayesian skill ratings + pattern extraction. Gets faster over time.
- **35 specialist agents** — auto-routes your request to the right expert (coder, researcher, writer, guardian, quant, and 30 more).
- **670+ tools** — files, bash, git, GitHub, web search, deploy, database, game dev, VFX, research, science, finance, security, and more.
- **Programmatic SDK** — use kbot as a library in your own apps.
- **MCP server built in** — plug kbot into Claude Code, Cursor, VS Code, Zed, or Neovim as a tool provider.

## Quick Start

```bash
# Install globally
npm install -g @kernel.chat/kbot

# Or run directly (no install)
npx @kernel.chat/kbot

# Or use the install script (auto-installs Node.js if needed)
curl -fsSL https://kernel.chat/install.sh | bash
```

```bash
# Interactive mode
kbot

# One-shot
kbot "explain this codebase"
kbot "fix the auth bug in src/auth.ts"
kbot "create a Dockerfile for this project"

# Pipe mode (for scripting)

Set any provider's env var and kbot auto-detects it. Or run `kbot auth` for interactive setup.

## SDK

```typescript
import { agent, tools, providers } from '@kernel.chat/kbot'

const result = await agent.run("fix the auth bug", { agent: 'coder' })
console.log(result.content)

for await (const event of agent.stream("explain this code")) {
  if (event.type === 'content_delta') process.stdout.write(event.text)
}
```
