 ## Core Commands
 
-- [CLI Usage](https://github.com/Panniantong/Agent-Reach/blob/main/docs/install.md): `agent-reach read <url>` reads any URL, `agent-reach search-twitter "query"` searches Twitter, etc.
+- [CLI Usage](https://github.com/Panniantong/Agent-Reach/blob/main/docs/install.md): `agent-reach doctor --json` shows the active backend; agents then call upstream tools directly (`opencli`, `twitter`, `bili`, `yt-dlp`, `gh`, `mcporter`, etc.).
 
 ## Key Features
 
-- Read any URL: tweets, Reddit posts, YouTube videos (transcripts), GitHub repos, articles, XiaoHongShu notes, Bilibili videos, RSS feeds
-- Search across platforms: Twitter/X, Reddit, GitHub, YouTube, Bilibili, XiaoHongShu, Instagram, LinkedIn, Boss直聘, Web (via Exa)

+- Search/discover across platforms: Twitter/X, Reddit, Facebook, Instagram user search, GitHub, YouTube, Bilibili, XiaoHongShu, LinkedIn, V2EX, Xueqiu, Web (via Exa)
 - Self-diagnosis: `agent-reach doctor` checks what works and what needs setup
 - Auto-installs dependencies: `agent-reach install --env=auto`
-- Cookie-based auth for platforms that require login (Twitter, XiaoHongShu, Instagram)
-- Proxy support for platforms that block server IPs (Reddit, Bilibili)
-- Zero API fees: all backends are free and open-source (bird CLI, yt-dlp, Jina Reader, instaloader, etc.)
