Claude Code Plugin Ecosystem Arrives — v2.1.129, Custom Themes, and Project Purge

On May 6, 2026, Claude Code v2.1.129 shipped with three standout features: install plugins from a URL with --plugin-url, build personal color palettes via /theme, and wipe project state cleanly with claude project purge. Anthropic also opened its official plugin directory. Claude Code is no longer just a tool — it is becoming a platform.
