Inclusion requirements
- Curated first: every feed belongs to a source on the Claude Ecosystem Radar — a 162-source directory built 2026-07-25 by a 12-agent research sweep with 370 live web checks.
- Verified live: each feed URL was fetched on 2026-07-25 and had to return valid RSS or Atom (not just HTTP 200 — several sites serve an HTML page at their old feed path).
- Fresh within 30 days: each feed had to contain at least one entry published on or after 2026-06-25. Feeds that failed this sit in the "Currently quiet" group at the bottom, unchecked, so you can still opt in knowingly.
How the picker works
- Tick feeds (or use a preset), then Copy OPML — paste into a text file saved as claude-radar-feeds.opml and import it; every feed reader accepts OPML. Show OPML reveals the same content in a select-and-copy box, and Copy URLs gives the selection as a plain list. (This page can't download files directly — artifact pages run in a sandbox that blocks downloads, so copying is the reliable path.)
- Your selection is saved in this browser (localStorage), so you can return and adjust later.
- Core 12 preset: the radar's "start here" shortlist. It selects 11 feeds — two core sources (@ClaudeDevs on X and the What's-new docs page) publish no RSS; the Claude Code releases feed covers the same ground, and a Mon/Thu radar agent sweeps the rest.
Feed mechanics worth knowing
- YouTube entries use YouTube's official per-channel RSS (youtube.com/feeds/videos.xml?channel_id=…) — channel IDs were extracted and verified per channel.
- GitHub entries use GitHub's native releases.atom / commits/main.atom feeds — no account needed.
- Reddit .rss endpoints work fine in feed readers but rate-limit aggressive polling — normal reader refresh intervals are fine.
- Hacker News uses hnrss.org, a community bridge; it was briefly returning 502s at verification time but is the canonical HN-search-to-RSS service.
- GeekNews (Korea) only offers an all-topics feed — Claude coverage is heavy but not exclusive.
What's deliberately missing
Sources with no working feed — the Anthropic newsroom, claude.com/blog, the engineering blog, the What's-new page, ClaudeFast, Every, Skills Weekly, PulseMCP, Star History, the leaderboards, X accounts, and Discords — are covered by the scheduled Mon/Thu radar agent instead, so nothing on the radar goes unwatched.
