What
Claude Code can now suggest installing a marketplace plugin when it notices a file extension that a language server plugin would help with. Accepting installs the plugin; choosing "disable" sets a stored lspRecommendationDisabled setting that stops the suggestion for good. The prompt appears at most once per session, and dismissing it without choosing counts as cancelled.
Details
- The suggestion carries the plugin name, its description, the marketplace it comes from, and the file extension that triggered it.
- Answers are yes, no, never, disable, timeout, or cancelled, with cancelled as the default outcome if nothing is chosen.
- Once-per-session suppression is tracked by a session flag, so restarting a session can bring it back unless you picked disable.
- This is separate from the pre-existing plugin hint prompt, which keys off commands you run rather than file types.
Evidence

Strings lifted out of the shipped bundle, so the claim above can be checked against them.
