Troubleshooting
| Problem | Fix |
|---|---|
| Plugin not appearing in Discover | Make sure the marketplace was added successfully in Step 2. Try /plugin > Marketplaces > check that xplusplusai/autoxpp-marketplace is listed. |
| MCP connection error after key setup | Restart Claude Code so the MCP server connects, then run /autoxpp-setup-api-key again to validate. |
| Skills show "locked" or "requires upgrade" | Your API key may be for the free tier. Visit xplusplus.ai/autoxpp to upgrade. |
| Free skills not working | Free skills (browser-v2, azure-devops, sql-jit, ude-switch) don't need an API key. Make sure the plugin itself is installed and enabled. |
