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 Control Minimum Version Enforcement

Feature flag
tengu_bridge_min_version Not enough to say

Nothing here resolved what this flag was doing on this version, so nothing here should be read as on or off.

This account: no value returned · anonymous baseline: no value returned · compiled default in v2.1.53: no gate table built for this version

These values were read against a different version of Claude Code, so treat them as the nearest reading available instead of one taken on this release.

Read once, for one account on one subscription tier, against v2.1.53. It isn't a statement about your account. What a flag value here can and cannot tell you

What

The bridge (Remote Control) system now checks a server-specified minimum version requirement and blocks connections from outdated CLI versions.

Details
  • On startup, the bridge checks the tengu_bridge_min_version feature flag for a required minimum version
  • If the running CLI version is too old, the user sees: "Your version of Claude Code (X.X.X) is too old for Remote Control. Version Y.Y.Y or higher is required. Run claude update to update."
  • This applies to both standalone claude bridge mode and in-session REPL bridge connections
Evidence

Version check using tengu_bridge_min_version flag (search for "tengu_bridge_min_version")

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