What
The warning that a reload will invalidate your prompt cache used to mention only MCP server changes. It now also says whether the reload adds or removes the LSP tool, softened to "may add"/"may remove" when the plugin loader failed in a way it can recover from.
Details
- The LSP part is skipped when LSP servers are disabled, when tool search is on, or when there are no cached tools to compare against.
Evidence
may add the LSP tool
Strings lifted out of the shipped bundle, so the claim above can be checked against them.
