What

Claude Code now reads two new switches that Anthropic's server can turn on or off per account.

  • tengu_foamy_rabbit: treated as on if the server sends nothing, but treated as off when an HTTPS proxy is set, unless another check passes.
  • tengu_lexical_parnas: read with no stated fallback.
Why

These are new remote controls over Claude Code's behaviour. If you use an HTTPS proxy, the first one behaves differently for you.
