DisclaimerUnofficial, and not affiliated with Anthropic. Nearly all of this is read straight out of what ships: npm bundles, captured prompts, published docs. Anthropic's own notes go in verbatim, marked as theirs. The rest is my reading, and every entry carries the strings behind it. If one looks wrong, vote it down and say why.

Remote-tools announce log counts only passthrough tools

Under the hood
Useful1 Signal2
Remote Tools

Remote machine announce logs now count only real passthrough tools.

What

The diagnostic logged when a remote machine announces itself no longer counts internal plumbing tools and only fires when at least one passthrough tool is present. The plumbing tools themselves, including the remote call and file-sync tools, are still defined and used.

Evidence

MCP tool(s) this worker does not take over the session channel yet

Strings lifted out of the shipped bundle, so the claim above can be checked against them.
