CLI agents can't reach login walls or video content: Agent Reach preinstalls the channels so one command reads them
Synopsis
Command-line AI agents such as Claude Code and Codex ship with search and web reading, yet they largely cannot reach platforms that require login, video subtitles and speech transcripts, Chinese platforms, or clean structured data. Agent Reach preinstalls and tests the upstream tools behind those platforms, so an agent calls them with one command in the form channel, action, arguments, and falls back to the next tool in an ordered list when the first fails. It only searches and reads, never logs in for you, and never asks for your password.
Interpretation
Command-line AI agents gain a directly callable external channel layer for platforms their own search and web reading cannot reach. These agents ship with search and web reading, but they largely cannot reach features behind a login, content inside videos, Chinese platforms, or clean structured data. Coverage is listed channel by channel: Bilibili, V2EX, GitHub, YouTube and the web work once installed, optional channels such as Xiaohongshu are added on request, and platforms with stricter anti-scraping are marked experimental.
Calls collapse into one command, with the agent requesting data as channel, action, arguments, or handing over a link and letting the tool pick the channel. Every action on every platform has an ordered list of upstream tools to try, for example reading a Bilibili video starts with bili-cli and falls back to Bilibili's public interface, while reading a web page starts with Jina Reader and then Exa. When a platform changes or a tool breaks, only that list is adjusted and the agent's usage stays the same; all channel tools, logins and settings sit in one local folder for easy upgrade and removal.
Login handling stays read-only, and platforms that need a login use Agent Reach's own dedicated browser running in the background. On first use of a site, the login for that site is copied from your Chrome, leaving the original browser unchanged and never reading the password store. The copied login is usually the main account, so the project recommends switching to a secondary account; the dedicated browser is reachable only from your own machine, and the agent never logs in for you or asks for a password.
Perspective
The material describes a channel access layer for command-line AI agents, covering default channels such as Bilibili, V2EX, GitHub, YouTube and the web, plus optional channels such as Xiaohongshu and platforms marked experimental; it only searches and reads, and does not post, comment, like or send direct messages.
The material marks some platforms as experimental, noting stricter anti-scraping and possible failure at any time; the copied login is usually the main account, and platforms may restrict accounts used for automated access, which is why the project recommends a secondary account.
