What

  • Adding a marketplace from a link or URL, whether via /plugin marketplace add <path/url> or by installing a plugin from a link, now carries a confirmAdd payload. The add-marketplace screen automatically shows a confirmation step when this hasn't been set yet but a link-based source was provided.
  • A new install-from-source action routes to the add-marketplace screen with plugin and link-origin details for this confirmation step.
  • A new usage-error fallback routes back to the plugin menu instead of failing silently.
  • Installing now short-circuits to an npm-install path when the target parses as a plugin@npm spec.

Why

This adds a safety check before trusting and adding a marketplace source from an arbitrary link, and cleans up how installs from different kinds of sources (links, npm packages, usage errors) are routed.
