Install for Claude Code
When to Use
Follow this process when setting up Modern Web Guidance for the first time in a Claude Code environment. The
npxuniversal installer (covered in Install for Other Agents) also works for Claude Code.
Decision
| Step | Command | Notes |
|---|---|---|
| 1. Add marketplace | /plugin marketplace add GoogleChrome/modern-web-guidance |
Claude Code slash command, not a shell command |
| 2. Install plugin | /plugin install modern-web-guidance@googlechrome |
|
| 3. Reload plugins | /reload-plugins |
Skill does not activate until plugins are reloaded |
| 4. Enable AutoUpdate | Via /plugin settings UI |
Keeps skill content current without manual updates |
Pattern
Run inside a Claude Code session:
/plugin marketplace add GoogleChrome/modern-web-guidance
/plugin install modern-web-guidance@googlechrome
/reload-plugins
Enable AutoUpdate: After /reload-plugins, run /plugin. In the plugin manager UI: select the GoogleChrome marketplace, press Enter, then enable AutoUpdate for modern-web-guidance.
Verify installation: After /reload-plugins, ask the agent a modern web task (e.g., "animate a dialog exit"). If MWG is active, the agent will invoke modern-web-guidance search before generating code.
Updating an existing install:
npx modern-web-guidance@latest update
Common Mistakes
- Skipping
/reload-plugins— the skill does not activate until plugins are reloaded - Running the commands outside a Claude Code session — these are Claude Code slash commands, not shell commands
- Not enabling AutoUpdate — MWG actively adds new guides; stale installs miss coverage for newly shipped features
