skillgild end <session-id>Run skillgild install frontend-design --agent claude-code and connect the SkillGild MCP server (skillgild mcp).

Yes. It includes 25 free runs every month on SkillGild. Frontend Design (Anthropic) is open source (Apache-2.0) by Anthropic; SkillGild packages it from https://github.com/anthropics/skills at a pinned commit and credits the author.
It runs in your coding agent with your own model. SkillGild checks your monthly allowance and delivers the skill's instructions for each session; it makes no model call and never sees your project unless your agent sends it.
The project lists Claude Code (plugin); any Agent Skills host via the skills repo. It is a plain Agent Skills folder (SKILL.md plus supporting files), so any client that reads that format can load it.
