## About

# E2E Flow Verifier

Product verification skill that drives user flows with the **qe-browser** fleet skill (Vibium engine), asserts state at each step, and records evidence as a ZIP of screenshots + DOM snapshots.

## Activation

```
/e2e-flow-verifier [flow-name]
```

## Dependency

This skill uses `.claude/skills/qe-browser/` for all browser automation. The `vibium` binary is installed automatically by `aqe init`. See `qe-browser/SKILL.md` for the full command reference.

## Flow Verification Pattern (qe-browser + batch + assert)

Define the flow as a JSON batch plan and drive it with the qe-browser batch runner:

```bash
# flows/{{flow-name}}.json
cat > /tmp/{{flow-name}}.json = 1`, `text_visible ` |

## Reusing auth state across runs

```bash
# Once: log in and save state
vibium go "{{base_url}}/login"
vibium fill "[data-testid=email]" "$USERNAME"
vibium fill "[data-testid=password]" "$PASSWORD"
vibium click "[data-testid=login-btn]"
vibium wait url "/dashboard"
vibium storage -o test-results/auth/state.json

# Every subsequent run
vibium storage restore test-results/auth/state.json
vibium go "{{base_url}}/dashboard"
```

## Gotchas

- **Re-map after DOM changes** — Vibium `@e1` refs are invalidated by navigation; use `vibium diff map` to see what changed and re-map if needed.
- **Selectors break on deployment** — prefer `data-testid` over CSS classes.
- **Auth tokens expire** — use fresh login per run, or rotate `storage` snapshots.
- **Evidence ZIPs grow** — keep failure runs only in CI, gc after N days.
- **No raw Playwright** — this skill used to use `@playwright/test`. If you need Playwright's network interception (`page.route`), use it in a separate skill and call it as a step; don't reintroduce the dependency here.
