Patch release (2.1.212 → 2.1.214): morning brief is removed, auto-mode safety and artifact publishing are tightened, and skills, focus mode, memory, and shell tooling guidance are refined.
Changelog
[removed] Morning brief is gone, including the brief skill/prompt path and related configuration.
[changed] Published artifacts no longer declare or guess runtime capabilities. If a capability is requested and unavailable, Claude says so and builds a static page instead of wiring live runtime connectors.
[changed] Auto-mode classifier rules are stricter: stage‑1 judgment errs on the side of blocking by full effect of the action, and classifier replies must begin with <block> with no preamble.
[changed] Skills discovery is more deliberate — avoid proactive skill search for one-off questions or repeats the user ignored; recommend standalone org/shared/Anthropic skills when the user asks or when nothing is enabled for the domain.
[changed] Focus mode instructions are clearer: only the final text message is shown, so progress chatter between tool calls is skipped and everything important goes in the final reply.
[changed] Bash/PowerShell guidance calls out NonInteractive execution with stdin on the null device (console prompts hit EOF/error immediately; GUI prompts can still block until timeout).
[changed] When the user asks Claude to remember something, it is directed to save that preference into its private memory directory for later sessions.
[changed] Computer-use MCP and Claude in Chrome decline paths are reworded so sessions continue cleanly without browser tools when the user opts out.
[fix] OAuth refresh handling is more resilient around dead/invalid grants, disk-cleared refresh tokens, and lock-retry limits.
[changed] GitHub PR status auth-state handling and related PR follow-ups (including optional Slack post when CLAUDE.md asks for it) are tightened.
Models & prompts
Plan mode, ambient-context, and long-conversation summarization prompts are refreshed so work continues cleanly after compacting without early handoff.
Reviewer/recall prompts and permission-denial wording are adjusted for clearer stop/retry behavior when a tool use is rejected.
Artifact publishing guidance no longer encourages declaring live mcp runtime capabilities against connected data sources by default.
Coordinator/multi-worker orchestration and task-list update tool text remain in place with minor wording polish.
Quiet-hours nudge copy is present for a one-time notice when the CLI is used inside the configured quiet-hours window.
Under the hood
Early Google Cloud wiring: ANTHROPIC_GOOGLE_CLOUD* settings and the https://claude.googleapis.com endpoint for Claude-on-GCP style deployments.
Import pipeline scaffolding (import / scan / apply / attachment success-error paths) for bringing external content into a session.
Org-memory decision and mirroring hooks, plus related experimental gates.
SDK file checkpointing flag, cold-compact path, optional append of subagent prompts, and a native-cursor experiment.
New controls for custom headers, custom model-option descriptions, OAuth scopes, resume prompt text, no-model-fallback, nonstreaming-fallback disable, first-party base-URL assumption, session-attribution suppress, force-bridge, bash project working-dir retention, OTEL content max length, and CLAUDE_PID.
Backend route for frame deploy completion; SDK compatibility list now includes 0.3.200.
Upgrade notes
Anything depending on morning brief setup or the old brief prompts will no longer work; remove or replace those workflows.
Artifact flows that previously assumed runtime connector capabilities should expect static pages unless those capabilities are actually available.
Auto mode may block more aggressively than before; review classifier/allow rules if legitimate actions are now stopped.
