A terminal browser powered by Carbonyl that gives agents direct DOM access while rendering visually for humans. No screenshots needed.

​
Start

In a separate terminal: 
./tools/browser/tenet-browser.sh https://10et.ai
The human sees the page rendered in their terminal. The agent gets structured DOM via CDP.

​
Agent commands (via Subway)

# Navigate
subway_call("browser.relay", "navigate", '{"url":"https://example.com"}')

# Read page structure (headings, forms, links, tables, errors)
subway_call("browser.relay", "read", '{}')

# Click an element
subway_call("browser.relay", "click", '{"selector":"#deploy-btn"}')

# Type into a field
subway_call("browser.relay", "type", '{"selector":"#search", "text":"error logs"}')

# Scroll
subway_call("browser.relay", "scroll", '{"direction":"down"}')

# Wait for element to appear
subway_call("browser.relay", "wait", '{"selector":".results", "timeout":5000}')

​
What agents get back

Not screenshots. Structured DOM: 
{
  "url": "https://app.example.com/dashboard",
  "title": "Dashboard",
  "dom_summary": {
    "headings": ["Dashboard", "System Health"],
    "forms": [{"id": "search", "fields": ["query"]}],
    "links": [{"text": "Settings", "href": "/settings"}],
    "tables": [{"id": "health-table", "rows": 5}],
    "interactive": [{"type": "button", "text": "Deploy"}],
    "errors": [],
    "text_content": "3 services healthy, 1 degraded."
  }
}

​
Human → Agent flow

When you click or type in the browser, events broadcast on the Subway mesh: 
{
  "type": "human_click",
  "element": {
    "tag": "div",
    "class": "error-banner",
    "text": "API timeout on /api/v2/health",
    "selector": "#dashboard > .error-banner"
  }
}
Your agent receives this and can respond: “I see you’re looking at the monitoring page — the 502s started 20 minutes ago…”

​
Authentication

No special auth system. The human is literally using the browser:
  1. Agent navigates to login page
  2. Human sees the form, types credentials in terminal
  3. Agent detects auth state change
  4. Agent proceeds with authenticated session

​
HTTP fallback

If Subway isn’t running, use the local API: 
curl -X POST http://127.0.0.1:9223/navigate -d '{"url":"https://example.com"}'
curl -X POST http://127.0.0.1:9223/read
curl -X POST http://127.0.0.1:9223/click -d '{"selector":"button.submit"}'
