npx skills add agentspace-so/runcomfy-agent-skillsInstall to a specific agent
Pick the agent you use. The CLI writes the skill to that agent's standard skill directory.

Prefer to skip the CLI? Clone the repo and drop the skill folder into your agent's skills directory.
git clone https://github.com/agentspace-so/runcomfy-agent-skills.gitcp -r runcomfy-agent-skills ~/.claude/skills/ For other agents, replace ~/.claude/skills/ with their skill directory — see the full list.
Use it
Once installed, ask your agent to "use the ace-step skill" or describe what you want (e.g. "Generate, inpaint, and outpaint music with ACE Step on RunComfy via the `runcomf"). Most agents auto-discover the skill from its SKILL.md description — no slash command needed.
