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 v2.1.224

Teammate mailbox failures are reported instead of silently swallowed

You'll notice
Useful3 Signal3
Team Messaging

Claude is now told when a message to a teammate did not get delivered.

What

When a write to a teammate's inbox fails, callers now check the result and tell the model the delivery did not happen, for example that a confirmation could not be written. Previously most of these call sites ignored the failure.

Details
  • The degraded-outcome path for a failed mailbox write went from one call site to nine.
  • Lock releases are wrapped so a failed release logs a warning instead of escaping the surrounding cleanup block.
  • Inbox write errors are now logged at error level and filtered before being surfaced.
Evidence

The confirmation could not be written to team-lead's inbox.

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