Unclear Whether the part of Claude Code that runs this watch is included in this build is not known.

What

When a session starts, Claude Code now starts an optional watch for an Artifacts MCP entry. MCP servers are add-ons that give Claude extra tools. If starting the watch fails, the error is caught and reported, and the session carries on.

Why

This is part of work on artifacts. A failure in it does not stop the session from starting.
