Install VS Code/Cursor extensions from a local .vsix via CLI (code, code-insiders, cursor, cursor-nightly). Use whenever asked to install an extension programmatically.

Install

npx vskill@latest install kevinslin/llm/dev-code-extension

SKILL.md

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)
bash
code --install-extension "/path/to/extension.vsix" --force
code --list-extensions --show-versions
VS Code Insiders
bash
code-insiders --install-extension "/path/to/extension.vsix" --force
code-insiders --list-extensions --show-versions
Cursor (stable)
bash
cursor --install-extension "/path/to/extension.vsix" --force
cursor --list-extensions --show-versions
Cursor Nightly

Prefer cursor-nightly if it’s on PATH. If not (macOS default), call it from the app bundle:

bash
"/Applications/Cursor Nightly.app/Contents/Resources/app/bin/cursor-nightly" --install-extension "/path/to/extension.vsix" --force
"/Applications/Cursor Nightly.app/Contents/Resources/app/bin/cursor-nightly" --list-extensions --show-versions

Verification

  • After install, verify by grepping the extension list:
  • cursor --list-extensions --show-versions | rg -n "<publisher>\\.<name>|<name>"

Automation/CI option (avoid touching a developer profile)

If the user wants isolated installs (recommended for scripts/CI), add:

  • --user-data-dir <dir>
  • --extensions-dir <dir>

Example:

bash
cursor --user-data-dir /tmp/cursor-user --extensions-dir /tmp/cursor-ext --install-extension "/path/to/extension.vsix" --force

Sandbox note (Codex CLI)

Installing extensions writes to user/application support directories (outside the repo). In sandboxed runs, request escalated permissions for these commands.
