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 v2.1.86

  • The CLAUDE_CODE_ENABLE_XAA=1 environment variable is required to use XAA features. Without it, servers configured with oauth.xaa will error on startup.
  • The --xaa, --client-id, and --client-secret flags are only supported for HTTP/SSE MCP transports and will be ignored for stdio.
  • The compact line prefix format and trusted device enrollment are behind feature flags and may not be active for all users yet.
