What
Claude Code now detects when two or more plugins declare LSP servers claiming the same file extension, and reports the conflict rather than silently picking one.
Details
- Conflicts are reported as
lsp-extension-conflictwarnings, including which plugin and server name is active for the extension vs. the newcomer. - The first plugin to register an extension wins; subsequent claims for the same extension are flagged.
Evidence
Conflict detection function (search for " declares two LSP servers for" in LSP warnings or "already registered a server for that extension")
Strings lifted out of the shipped bundle, so the claim above can be checked against them.
