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.

Set ANTHROPIC_PROFILE to pick which stored credential profile workload-identity login uses.

ANTHROPIC_PROFILE
What

Set ANTHROPIC_PROFILE to choose which stored credential profile is used when authenticating through workload identity federation. Without it, the previously active profile is used.

Details
  • Config resolution now reads the profile name from the environment before falling back to the recorded active profile.
  • Adds an async read-ahead that pulls active_config and configs/<profile>.json through the storage backend into a primed-file map before the synchronous readers run.
  • The read-ahead only happens when a storage host is serving; if the backend throws, it logs a warning and the normal file reads proceed.
