feat: add FlightHub domain skill for flight search automation

[PinkClaw]

Summary

Adds a domain skill for FlightHub.com flight search automation, covering:

• Cloudflare anti-bot protection — the JS challenge that blocks curl/web_extract, and how a real browser session passes it
• Direct search URL format — parameterized URL that bypasses the unautomatable custom datepicker entirely
• UI form interaction — airport POI autocomplete via CDP keyboard events (works), datepicker investigation (custom component that rejects all programmatic click methods)
• Results extraction — waiting for loading dialog, CSS selector heuristics for flight cards
• Key lessons — real browser requirement, datepicker blocking status, JS-driven form submission

Testing

All techniques field-tested on 2026-05-22 using browser-harness + Mac Chrome CDP against live FlightHub.com.

Summary by cubic

Adds a FlightHub.com domain skill that shows how to automate flight searches with a direct URL and a real browser, avoiding the click‑resistant datepicker. Includes anti-bot handling, minimal UI interactions, and reliable result extraction tips.

• New Features
  • Adds agent-workspace/domain-skills/flighthub/flights-search.md.
  • Documents Cloudflare JS challenge and the need for a real browser (CDP/Playwright + residential IP).
  • Provides a parameterized direct search URL and recommends this path over UI entry.
  • Notes UI behavior: POI autocomplete works via keyboard events; datepicker rejects programmatic clicks; search is a <div> that needs CDP click.
  • Outlines results-page wait strategy and broad selectors/snippet for extracting flight cards; mentions order_by options.
