Fully qualified tool names

Prompt files and custom chat modes enable you to specify which tools can be used. To avoid naming conflicts between built-in tools and tools provided by MCP servers or extensions, we now support fully qualified tool names for prompt files and chat modes. This also helps with discovering missing extensions or MCP servers.

Tool names are now qualified by the MCP server, extension, or tool set they are part of. For example, instead of codebase, you would use search/codebase or list_issues would be

 

You can still use the previous notation, however a code action helps you migrate to the new names.
