@reactive-agents/cli — rax

The Reactive Agents eXecutable — CLI for scaffolding, running, and inspecting AI agents.

Installation

# Global install
bun add -g @reactive-agents/cli

# Or run without installing
bunx @reactive-agents/cli --help

Commands

rax init <name> [--template minimal|standard|full]
  Scaffold a new Reactive Agents project

rax create agent <name> [--recipe basic|researcher|coder|orchestrator]
  Generate an agent file in your project

rax run <prompt> [--provider anthropic|openai|ollama|gemini|litellm|test] [--model <model>] [--name <name>] [--stream] [--cortex]
  Run an agent with a prompt and print the result. `--cortex` calls `.withCortex()` so events stream
  to a local Cortex studio. Launch the studio with `rax cortex` (after `bun add @reactive-agents/cortex`)
  or, in the source repo, with `bun cortex`. Override the ingest base URL with `CORTEX_URL` (default
  `http://127.0.0.1:4321`).

rax cortex [--port <n>] [--no-open] [--help]
  Launch the Cortex companion studio (UI + API for visual agent inspection). Requires
  `@reactive-agents/cortex` to be installed (lazy peer dep — `bun add @reactive-agents/cortex`).

rax dev [--entry src/index.ts] [--no-watch]
  Run your local agent entrypoint in watch mode

rax eval run --suite <name>
  Run an evaluation suite

rax playground
  Launch an interactive agent REPL session

rax inspect <agent-id> [--logs-tail 200] [--json]
  Inspect local deployment signals and recent matching logs

rax deploy up [--target local|fly|railway|render|cloudrun|digitalocean] [--mode daemon|sdk] [--dry-run]
  Build + deploy agent container through provider adapters

rax deploy down [--target <target>]
  Stop deployment (target auto-detected from config)

rax deploy status [--target <target>]
  Show deployment status (target auto-detected from config)

rax deploy logs [-f] [--target <target>]
  Tail deployment logs (target auto-detected from config)

rax version
  Print version

Deploy Provider Contracts

Deploy adapters are validated with CLI contract tests so upstream CLI changes can trigger early patches.

bun test apps/cli/tests/cli-contracts.test.ts
RUN_SLOW_TESTS=1 bun test apps/cli/tests/cli-contracts.test.ts

Baseline contract checks include:

• Docker >= 20, Compose >= 2
• gcloud >= 380.0.0
• doctl >= 1.72.0
• Fly/Railway/Render command and flag availability for adapter-invoked subcommands

Containerized fallback CLIs (flyctl, gcloud, doctl) are supported when Docker is available.

Examples

# Scaffold a new project with all features
rax init my-ai-app --template full
cd my-ai-app
bun install

# Generate a research agent
rax create agent researcher --recipe researcher

# Run a one-off prompt
export ANTHROPIC_API_KEY=sk-ant-...
rax run "Summarize the state of fusion energy" --provider anthropic

# Cortex studio: visual UI + API for inspecting agents. Two ways:
# (a) From any project — install once, run anywhere:
bun add @reactive-agents/cortex
rax cortex
# (b) From the source repo — server + Vite UI in dev mode:
# git clone https://github.com/tylerjrbuell/reactive-agents-ts && cd reactive-agents-ts && bun install && bun cortex
# Then in another terminal, stream run events into the studio:
rax run "Research topic X" --cortex --provider anthropic
