Browser Click Workflow Example

This example demonstrates a serial multi-node workflow over a trusted Python source:

open_click_page -> wait_for_click -> collect_snapshots

It opens a local HTML page with one visible button, captures a bounded JSON snapshot before the click, performs a deterministic simulated click by default, captures an after snapshot, closes the local server, and returns both snapshots as workflow output.

The example deliberately avoids browser screenshots and base64 payloads. The snapshots are small JSON objects suitable for CLI and LLM-agent output.

Run

From the repository root:

uv run wf config validate examples/browser_click_workflow/wf.config.json
uv run wf-rpc-server --config examples/browser_click_workflow/wf.config.json

In another terminal:

uv run wf --config examples/browser_click_workflow/wf.config.json status
uv run wf --config examples/browser_click_workflow/wf.config.json cap list --source local.browser_click

The full artifact/deployment/run lifecycle is covered by:

uv run pytest tests/examples/test_browser_click_workflow_example.py -q

Manual Browser Mode

The checked-in test uses "simulate": true and "open_browser": false. For manual experimentation, set "open_browser": true in the run input and use "simulate": false; then click the button before timeout_seconds elapses. Any browser or local server opened by the source is closed by the final collect_snapshots node.
