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.

Claude Code v2.1.124

isolatePeerMachines setting (Remote Control safety)

What

A new boolean setting that requires explicit user approval before SendMessage can reach a peer Claude Code session running on a different machine via Remote Control.

Usage (in settings.json):

{
  "isolatePeerMachines": true
}
Details
  • When the latch is engaged for a session it is persisted to the JSONL session log as isolation-latch events (sticky type) so resumed sessions inherit the side they were locked to.
  • Setting description: Require explicit approval before SendMessage can reach a peer session on another machine via Remote Control.
Evidence

Setting schema and runtime check (search for "isolatePeerMachines" and "isolation-latch").

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