## Sessions
Sessions allow multiple agents to use veb simultaneously without interfering:
Run multiple isolated browser instances:
```bash
# Using --session flag
veb --session agent1 open https://site-a.com
veb --session agent2 open https://site-b.com
# Different sessions
veb --session agent1 open site-a.com
veb --session agent2 open site-b.com
# Using environment variable
export VEB_SESSION=agent1
veb open https://example.com
# Or via environment
VEB_SESSION=agent1 veb click "#btn"
# List all running sessions
# List all
veb session list
# Close a specific session
veb --session agent1 close
```
## Selectors
veb supports all Playwright selectors:
```bash
# CSS
veb click "#id"
veb click ".class"
veb click "div.container > button"
veb click "div > button"
# Text
veb click "text=Click me"
veb click "text=Submit"
# XPath
veb click "xpath=//button[@type='submit']"
veb click "xpath=//button"
# Semantic (recommended)
veb role button click --name "Submit"
veb label "Email" fill "test@test.com"
veb find role button click --name "Submit"
veb find label "Email" fill "test@test.com"
```
## Agent Mode
Use `--json` for machine-readable output:
```bash
veb snapshot --json
veb get text "h1" --json
veb is visible ".modal" --json
```
