Windsurf Plugins — FAQ
How do I install plugins for Windsurf?
Install the BuySkills CLI globally (or use npx) and run `npx buyskills install <skill>`. The CLI auto-detects Windsurf and writes the skill into the correct directory. No manual config required.
Are Windsurf plugins paid or free?
Both. BuySkills is a marketplace where creators choose — some skills are free and community-maintained, others are paid one-time purchases. You see the price on each listing before installing.
Can I use the same skill with other AI agents besides Windsurf?
Yes. BuySkills was built for cross-agent portability. One install gives you the skill in every supported agent (Claude Code, Cursor, Windsurf, and 14+ others). No duplicate purchases.
Do updates to Windsurf break installed skills?
No. BuySkills uses semantic versioning and a shared registry, so skills stay pinned to the version you installed. Run `npx buyskills update` when you want the latest versions.
Do skills work with Windsurf's Cascade agent?
Yes. BuySkills installs skills into Windsurf's shared skill directory, and Cascade picks them up without restart. Skills are available the moment Cascade decides to use them in a workflow.
