Claude Code 2.1.317 asks before sending your email address to the network and adds a gateway cost report

Claude Code v2.1.317, released November 2, 2026, per its release notes:

• Privacy check: web and shell tool calls now ask before sending your account email address to the network.
• Agent SDK: hook callbacks accept onFailure: "block", so a callback that fails blocks the action instead of letting it run.
• Claude apps gateway: a new admin API report, GET /v1/organizations/analytics/cost, returns past spend over a date range in total, per developer, per day or per IdP group. The gateway also keeps a daily record of each developer's IdP groups (with admin: set, for admin.identity_retention_days), which the report groups by.
• Scheduled tasks: /schedule warns when a new cloud scheduled task gets connectors you did not ask for, and says how to remove them.
• Telemetry: OTel metrics, events and spans gain anthropic.plan, anthropic.seat_type, anthropic.provider and anthropic.custom_base_url.
• Behavior changes: subagents and teammates on a different model from the main conversation use that model's saved or default effort level, not the session's; the Read tool's "file unchanged since your last Read" stub is removed, so reading an unchanged file again returns its content; a message sent to a running background agent now moves its running command to the background without stopping it.
• New setting: CLAUDE_CODE_DISABLE_NESTED_SESSION_ID=1 on a self-hosted runner makes claude -p run inside a session use that session's ID and transcript, as in earlier versions. By default it no longer shares them.
• Notable fixes: claude -p now exits 1 with an error when a full disk or quota loses its transcript writes; claude auth status no longer exits before a slow token refresh is saved; partial Grep and Glob results are no longer treated as complete when a search hits its time limit; DISABLE_PROMPT_CACHING_OPUS and DISABLE_PROMPT_CACHING_SONNET now apply to [1m], other-region and undated spellings of the default model.

The release also carries many smaller fixes for the VS Code extension, Windows, self-hosted runners, cloud sessions and Remote Control.
