# Claude Code 2.1.318 records mod answers and adds AWS assume_role

> Claude Code 2.1.318 records answers to agent-written mod prompts, adds per-mod effort, and supports assume_role for AWS cost attribution.

Claude Code 2.1.318 was published on November 4, 2026. It records the answer you give when Claude Code asks to turn on mods it wrote in the session, lets a mod's model fork set its own effort, and adds `assume_role` on mantle upstreams of the Claude apps gateway.

## Mod answers are recorded

The release adds a record of your answer when Claude Code asks to turn on the mods it writes in a session. Where that record is stored, and how you read it back, is not in the notes. The new fact is that the answer itself is kept.

## Effort on a mod fork

A mod's `$.model.fork` now has an `effort` option. A quick side job can run at `low` whatever effort the session uses, and the result reports the effort that was sent. The notes name `low`. Other accepted values are not listed.

## A role in another AWS account

`assume_role` is on `mantle` upstreams of the Claude apps gateway, for a role in another AWS account and for per-developer AWS cost attribution. The notes do not include the configuration fields or how that attributed cost is reported.

## Stored sign-in expiry

The date a stored claude.ai sign-in ends is now in `claude auth status` as `loginExpiresAt` and in `claude -p` JSON results as `credential_expires_at`. Text output from `claude -p` prints a one-line stderr warning starting 10 days before that sign-in ends.

When a stored claude.ai login reaches its time limit, the sign-in failure now says so. In `claude -p` it names `claude auth login` and `claude setup-token`.

## Fixes that change whether work survives

The tag also includes a long fix list. A few sit next to consent, config, and long-running sessions:

- `--continue` sometimes lost the earlier conversation after a malformed tool call's retries ran out, a regression in 2.1.314.
- macOS sessions with many running Bash commands could stall while memory grew.
- On a shared network home, `/logout`, `claude auth logout`, and `claude mcp remove` could report success when the config file could not be updated, and changes to trust, consent, or MCP settings could be dropped with no word. Saves of `~/.claude.json`, settings files, and the stored login on those directories are less often deleted, briefly emptied, or replaced by a near-empty or older copy.

`claude mcp add` and `remove` now wait for the config lock or exit 1. Another job's save can still replace a saved server.

Read the v2.1.318 release notes before enabling `assume_role` on a shared gateway. If unattended jobs use a stored claude.ai sign-in, check `loginExpiresAt` in `claude auth status`.
