ACOS skill and command files use ~~category as a placeholder for whatever tool is configured for that category. For example, ~~image generation might mean Gemini 2.5 Flash Image via the nano-banana MCP server, or any other connected image generation tool.
ACOS is tool-agnostic at the skill level — workflows describe what needs to happen in terms of categories, not vendor names. Configure your specific tools in .mcp.json and your local Claude settings.

Multimodal Studio: image, video, and character generation are unified under one connector
(Higgsfield MCP — one OAuth, 30+ models). The multimodal-studio skill and /studio command
drive it. Connect with:
claude mcp add --transport http --scope user higgsfield https://mcp.higgsfield.ai/mcp
Skills stay vendor-agnostic — any MCP filling these categories works.

Update ~/.claude/settings.json to enable them
Skill files will work with any tool in the category — placeholders don't need to match specific vendors
