Anthropic's Claude Code v2.1.318 release adds a record of mod activation answers, an `assume_role` for AWS cost attribution, an `effort` option for `$.model.fork`, and sign-in expiry details, alongside numerous bug fixes across various functionalities.

READY TO POST:

claude code just dropped v2.1.318! looks like they're tracking mod activation answers now and have an "effort" option for model forks. neat for fine-tuning how side jobs run.

devs using claude code, check out v2.1.318. new `assume_role` for aws cost attribution is in, plus more visibility into sign-in expiry. lots of fixes for macos, tool calls, and remote sessions too.
