What problem does it solve? Gathering information from the internet requires juggling dozens of platforms—search engines, social media, developer tools, video sites—each with different APIs, authentication requirements, and CLI tools. This Skill acts as a unified router that picks the right backend for each platform and handles login-state checks, retries, and fallbacks automatically. ## Core Features & Use Cases - Multi-Platform Routing: Covers 15 platforms including Exa search, Twitter/X, Xiaohongshu, Bilibili, Reddit, LinkedIn, GitHub, YouTube, V2EX, Facebook, Instagram, RSS, and Xiaoyuzhou podcasts, with per-platform backend selection via agent-reach doctor --json. - Zero-Config Channels: Six channels work immediately—Exa web search, Jina Reader for webpages, GitHub CLI, yt-dlp for YouTube subtitles, V2EX public API, and bili-cli for Bilibili. - Authenticated Backends with Retry Chains: For login-required platforms, routes between OpenCLI (browser session reuse), platform-specific CLIs, and MCP servers, with documented fallback sequences when commands fail. - Use Case: A user asks to research how people are discussing a new AI product. The agent runs Exa for web coverage, checks Twitter and Reddit for discussion, scans Xiaohongshu and Bilibili for Chinese-language reactions, then compiles a cross-platform summary. ## Quick Start Ask the agent to research a topic across the internet, for example: "Use agent-reach to research what people are saying about the latest Claude model on Twitter, Reddit, and Xiaohongshu."
