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 Machines

Claude no longer gets told which remote machines are attached or how to route work to them.

What

The prompt section that listed the machines attached to your session, explained how to route a tool call to a named machine, and named a default machine for builds and long-running work has been deleted, including its REPL-specific await form.

Evidence

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