Source Intelligence

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.

IDE hosts can ask whether Remote Control could ever work

Under the hood
Useful2 Signal3
IDE Integration

Editors can now ask whether Remote Control could ever work in your deployment.

What

The handshake an editor extension makes with Claude Code can now return remote_control_available, saying whether Remote Control is possible in this deployment at all: not turned off by managed settings, not running inside a remote environment, and on a first-party provider. Editors can use it to hide the Remote Control affordance where it can never work. Older CLIs omit the field, and it is treated as available.

Details
  • Deliberately separate from transient state such as whether you are signed in or in the rollout, so hiding the UI is a permanent decision rather than a flicker.
Evidence

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