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.

Design OAuth refresh lock holds longer and reports compromise

You'll notice
Useful2 Signal0
Elsewhere

Slow token refreshes no longer trip the lock early, cutting spurious login hiccups.

What

The lock guarding OAuth token refresh tolerates slower refreshes and lets the holder find out if its lock was taken away mid-flight.

Details
  • Stale window raised from 10s to 60s, with a 5s update interval.
  • The callback now receives an object exposing isCompromised().
  • Lock contention throws a dedicated error class rather than a bare Error.
