Claude Tag: Not Your Personal Secretary, It's the Whole Channel's Teammate

Claude Tag is Anthropic's second-generation Claude in Slack, launched June 2026. Unlike typical chatbots: one thread is one persistent work session, and anyone in the channel can jump in mid-conversation to steer it. But the sandbox evaporates, and credentials never enter the sandbox — this security design is the baseline we'll compare against when we build our own.

Self-Hosting Your Own Claude Tag on LINE

Claude tag only officially supports Slack. Want an AI assistant that comes when you call on LINE? Build it yourself. Use OpenClaw to spin up a LINE bot on a VPS — messages come in from LINE's official cloud, the gateway catches them, and the agent replies. This post covers the replicable skeleton, three security must-haves, and why freedom always comes with responsibility.

The "Intranet Claude Tag": Enterprise Deployment and the Post Office Problem

A team wants OpenClaw on their intranet, coworkers tagging it in Teams. Outbound is sorted via a forward proxy. But inbound? Teams messages come from Microsoft's cloud — pure intranet is physically impossible. The post office problem: what moves inside the building (GitLab issues), what needs a door (DMZ + Teams), and why the extra architecture hassle is the right answer.
