Claude Code v2.1.318

Claude Code v2.1.318 adds an effort option for quick forked side jobs in mods, shows when a stored claude.ai sign-in expires (with a warning 10 days ahead in claude -p), and adds assume_role for AWS upstreams on the Claude apps gateway, plus dozens of reliability fixes for shared network home folders and cloud sessions.

Why it matters

For developers and admins running Anthropic's Claude Code agent, especially in scripts, CI or shared machines. Headless jobs now warn before a stored login runs out, and many fixes stop config files and logins being lost on network home directories.

What's new

A mod's $.model.fork accepts an effort option, so a quick side job can run at low effort whatever the session uses.
claude auth status shows loginExpiresAt and claude -p JSON results include credential_expires_at; text output prints a stderr warning starting 10 days before a stored claude.ai sign-in ends.
The Claude apps gateway adds assume_role on mantle upstreams, for a role in another AWS account and per-developer AWS cost attribution.
Fixes include --continue losing earlier conversation after failed tool-call retries (a 2.1.314 regression), macOS sessions stalling with many running Bash commands, and claude mcp add/remove writing config without its lock.
Claude Code no longer installs or updates the IDE extension when started in an IDE terminal; cloud sessions can now start with no repository.

Taken from the project's own release notes. Claims about speed or accuracy are the maker's unless stated otherwise.

Try it if: You run claude -p in scripts or CI and want warning before a stored login expires, or your team shares network home folders.
