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.

Permission responses are checked against the tool they were issued for

Permissions

A permission answer meant for a different tool is ignored, so nothing gets wrongly approved.

What

A can_use_tool answer that names a different tool than the one being asked about is now ignored, so a stale or crossed response cannot approve the wrong call.

Details
  • both the SDK control-protocol client and the remote permission bridge record the pending tool name
  • the hook and permission response schema gained an optional toolName field
  • telemetry distinguishes a match from a mismatch
  • in the remote session manager, a mismatch is logged and the local prompt stays up rather than being dismissed, since the worker would drop the answer anyway
Evidence

bridge_permission_toolname_check, worker will drop it, keeping prompt

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