## Workflow

1. `snapshot` first - always start here to get element refs
2. Use refs [e1], [e2]... with `click`/`type`/`fill`
3. `snapshot` again after actions to see results
4. Use `find` to locate elements without a full snapshot
5. Use `get` to extract specific data from elements
6. **Only use `screenshot` if:**
   - Snapshot is missing expected content
   - Page has complex visuals (charts, images, canvas)
   - Debugging why an action didn't work

## Examples

```bash
# Search Google
npx tab-agent navigate "https://google.com"
npx tab-agent snapshot
npx tab-agent type e1 "hello world"
npx tab-agent press Enter
npx tab-agent snapshot  # See results

# Find and click a button by text
npx tab-agent find text "Sign In"
npx tab-agent click e1

# Extract data
npx tab-agent get text e5
npx tab-agent get attr e3 href

# Save page as PDF
npx tab-agent pdf report.pdf
```

## Notes

- Refs reset on each snapshot - always snapshot before interacting
- `find` assigns new refs without resetting existing ones
- Keys: Enter, Escape, Tab, Backspace, ArrowUp/Down/Left/Right
- Prefer snapshot over screenshot - faster and text-based
- Use `--browser=safari` or `--browser=chrome` to target specific browser
