Source Intelligence

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 v2.1.21

For SDK users: The onCompactProgress callback replaces setSpinnerMessage for hook events. Update your integration to handle the new structured events:

{
  type: "hooks_start",
  hookType: "pre_compact" | "session_start"
}

For enterprise users: If remote sessions stop working, check with your organization admin about the new allow_remote_sessions policy. This is controlled at the organization level via the policy limits API.
