Claude Code 2.1.218 just landed on the next channel, and it's a big one: /artifact-pr-review lets you publish an interactive PR review page that collaborators can click through — and Claude can read their answers back. 🧵 1/7

6/7 Smaller but handy: SendFeedback now shows an inline card so you can approve a Claude-drafted bug/feature report with one click. Left-arrow now needs a second press to navigate away when the input is empty, fixing accidental navigation while editing. A new MCP client "v2" runtime is also staged behind a flag — no visible change yet.

7/7 Also: ultrareview now shows an estimated cost before launch and stops misreading free-text notes as a base branch; auto-mode permission-classifier calls can now be queued (behind a flag); and prompt history is flushed on exit so you stop losing typed prompts on quit.

1/6 Claude Code 2.1.217 is out on the next channel 👀 Highlights: a Memory viewer where you can rate & delete what Claude recalled, a new /explain-usage command, a /simplify cleanup workflow, and configurable subagent limits. Plus big infra groundwork for server-dispatched workflows. Thread:

5/6 Hardening batch: the updater can now self-heal a broken "claude" binary after a failed auto-update (restores from a preserved copy), worktree-isolated sessions block sketchy path spellings (UNC shares, symlink tricks), and repo-committed settings can no longer silently redirect your proxy/TLS traffic.

6/6 Behind the curtain: a "workflow_launch" system lets Anthropic's servers dispatch signed workflow bundles straight into remote (Claude app-connected) CLI sessions — infra-only for now. Also in the works (flags off by default): local transcript compaction to shrink .jsonl files, and a usage-limit "grace window" that has Claude wrap up gracefully instead of cutting off mid-task.

Claude Code 2.1.216 (npm "next") is a big one: artifacts get a full publishing platform — multi-file pages plus a live-watch subscription system — and Auto mode is now the default permission mode. Thread on what's new 🧵 1/7

Also in this release: - A new cost report shows 7-day token usage and system-prompt overhead per skill, flagging ones that are loaded but never actually used - In-CLI spend limit & auto-reload management for your API credits (flag-gated rollout) - Resuming a session now falls back gracefully if the agent it used no longer exists, instead of failing 6/7

Plus a wave of security hardening: symlink/race-condition protection in Rewind and claude rm, SSRF-style blocking for the new artifact network calls, JWT-aware credential masking in sandboxes, and stricter Linux sandboxing (cap-drop ALL). 7/7
