- ❓ Are images from Kagi proxy covered by CC BY-NC? - - ❓ Do we need to attribute original image sources? - - **Action:** Email support@kagi.com for clarification +The Kagi News RSS Aggregator implementation is complete and ready for integration testing and deployment. All 7 core components have been implemented with comprehensive test coverage (57 tests, 83% coverage). -2. **Hotlinking Policy:** - - ❓ Is embedding Kagi proxy images acceptable? - - ❓ Should we download and re-host? - - **Action:** Test in staging, monitor for issues +**What Was Built:** +- Complete RSS feed fetching and parsing pipeline +- HTML parser that extracts all structured data from Kagi News feeds (summary, highlights, perspectives, quote, sources) +- Rich text formatter with proper facets for Coves +- State management system for deduplication +- Configuration management with YAML and environment variables +- HTTP client for Coves API authentication and post creation +- Main orchestrator with robust error handling +- Comprehensive test suite with real feed fixtures +- Documentation and example configurations -3. **Category Discovery:** - - ❓ How to discover all available category feeds? - - ❓ Are there categories beyond world/tech/business/sports? - - **Action:** Scrape https://news.kagi.com/ for all .xml links +**Key Findings:** +- Kagi News RSS feeds contain only 3 structured sections (Highlights, Perspectives, Sources) +- Historical context is woven into the summary and highlights, not a separate section +- Timeline feature visible on Kagi website is not in the RSS feed +- All essential data for rich posts is available in the feed +- Feed structure is stable and well-formed -4. **Attribution Format:** - - ❓ Is "πŸ“° Story aggregated by Kagi News" sufficient? - - ❓ Do we need more prominent attribution? - - **Action:** Review CC BY-NC best practices +**Next Phase:** +Integration testing with live Coves API, followed by alpha deployment to test communities. --- -## References - -- Kagi News About Page: https://news.kagi.com/about -- Kagi News RSS Example: https://news.kagi.com/world.xml -- Kagi Kite Public Repo: https://github.com/kagisearch/kite-public -- CC BY-NC License: https://creativecommons.org/licenses/by-nc/4.0/ -- Parent PRD: [PRD_AGGREGATORS.md](PRD_AGGREGATORS.md) -- Aggregator SDK: [TBD] +**End of PRD - Phase 1 Implementation Complete** -- 2.51.2
