Claude Code v2.1.275/276: claude.ai skill sync, ctrl+enter send-now, npm plugin hardening
Anthropic
Follow-up to yesterday's v2.1.274: v2.1.275 (Sep 17) syncs claude.ai-enabled skills and plugins into terminal sessions, adds ctrl+enter to interrupt a turn and flush queued messages, installs plugins via --marketplace using npm with install scripts disabled, and stops leaking secrets in marketplace/git URLs. v2.1.276 (Sep 18) fixes a 275 regression that broke every request behind a custom ANTHROPIC_BASE_URL gateway.
Why it matters
Skill/plugin sync plus script-free npm installs close the biggest social-engineering hole in Claude Code's plugin path; the immediate 276 hotfix shows how much of the user base runs behind gateways.
Importance: 2/5
