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.

Workers retry reading session auth headers at startup

Under the hood
Useful2 Signal2
Background Work

A worker starting before its auth headers arrive now retries instead of dying.

What

A worker that starts before its session authentication headers are available now re-reads them on a fixed delay schedule rather than failing outright, so a slow handoff no longer kills the worker.

Details
  • Each attempt logs [remote-io] no auth headers, re-reading in ${...}ms.
  • Success reports cli_worker_lifecycle_init_auth_retried at info level; running out of attempts reports cli_worker_lifecycle_init_auth_retry_exhausted at error level with the attempt count and diagnostics. Both event names are new in this build.
Evidence

cli_worker_lifecycle_init_auth_retry_exhausted, cli_worker_lifecycle_init_auth_retried, [remote-io] no auth headers, re-reading in

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