dev.code-extension

Use this skill when the user asks to install a VS Code-compatible extension into VS Code or Cursor (stable or nightly).

Input contract

• Expect a local filesystem path to a .vsix file.
• If the user provides a Marketplace ID instead of a path, ask for the .vsix path (unless they explicitly want Marketplace install).

Install commands (local .vsix)

VS Code (stable)

code --install-extension "/path/to/extension.vsix" --force
code --list-extensions --show-versions
