feat: enrich Expedia domain skill with field-tested browser-harness findings

[PinkClaw]

Summary

Substantially enriches the existing Expedia.ca domain skill with findings from real browser-harness + Mac Chrome CDP field testing (2026-05-22):

Key additions

1. Mac Chrome + residential IP works — contradicts the earlier assumption that a cloud browser with residential proxies is required. With real Chrome on a home ISP, DataDome passes without captchas.

2. goto_url() + new_tab() fallback pattern — navigate silently first, open new tab only if results don't load. Avoids unnecessary macOS window popups.

3. [data-stid*="listing"] selector — the working selector for the URL-preload results page. Extracts up to 200 listings.

4. CRITICAL: Do NOT click Search with URL pre-load — the pre-filled URL already returns results. Clicking Search reloads the page and resets any applied filters.

5. Stop filter exclusivity — each checkbox shows exactly that stop count (not cumulative). Nonstop = 0 stops only, 1 stop = exactly 1 stop. Must click both with 5+ second waits for 0 OR 1 stop results.

6. Dynamic filter IDs — filter IDs have random suffixes. Match by aria-label instead of hard-coded IDs.

7. 10 key lessons — comprehensive lessons section covering all field-tested quirks.

Testing

All additions field-tested on live Expedia.ca using browser-harness with Mac Chrome CDP proxy.

Summary by cubic

Enriches the Expedia.ca flight search domain skill with field-tested guidance for stable automation and higher success rates. Also fixes a broken post-search selector in examples to prevent timeouts.

• New Features

  • Added agent-workspace/domain-skills/expedia/flights-search.md with tested patterns and 10 key lessons.
  • URL-first flow with goto_url() + new_tab() fallback; do not click Search when the URL is pre-filled.
  • Verified that real Mac Chrome + residential IP passes DataDome; use cloud + residential proxy only for datacenter IPs.
  • Working results selector div[data-stid*="listing"] and examples to extract up to 200 listings.
  • Documented stop filter exclusivity and dynamic filter IDs; match by aria-label and wait 5+ seconds between filter clicks.
  • Guidance on fresh browser contexts, non-headless mode, and 15–30s waits for /Flights-Search loads.

• Bug Fixes

  • Replaced [data-testid*="flight"] with div[data-stid*="listing"] in the post-search wait example to avoid result-load timeouts.
