Superpowers-CCG is a fork/enhanced variant of obra/superpowers. It keeps the same skills-driven workflow, and adds CCG multi-model collaboration: Claude orchestrates, and can route to Codex MCP (backend) and Gemini MCP (frontend) with optional cross-validation.

• Multi-model routing (CCG): route tasks to Codex (backend) / Gemini (frontend), or use CROSS_VALIDATION when uncertain.
• MCP tool integration: external calls go through MCP tools: mcp__codex__codex, mcp__gemini__gemini.
• Collaboration checkpoints: CP1/CP2/CP3 checkpoints embedded in key skills to decide when to call external models.

• Claude Code CLI installed (claude --version)
• uvx available (used by the MCP server install commands below)

1. Add marketplace

/plugin marketplace add https://github.com/BryanHoo/superpowers-ccg

2. Install plugin

/plugin install superpowers-ccg@BryanHoo-superpowers-ccg

After installation, configure Codex MCP and Gemini MCP so the orchestrator can route work to them.

claude mcp add gemini -s user --transport stdio -- uvx --from git+https://github.com/GuDaStudio/geminimcp.git geminimcp
claude mcp add codex -s user --transport stdio -- uvx --from git+https://github.com/GuDaStudio/codexmcp.git codexmcp

You typically do not call MCP tools manually. Instead, tell Claude what you want, and the workflow will decide when to invoke external models.

• Ask for backend help: "Use Codex MCP for the API/database parts, return a patch only."
• Ask for frontend help: "Use Gemini MCP for UI/components/styles, return a patch only."
• Ask for extra confidence: "Do CROSS_VALIDATION (Codex + Gemini) for this design, and reconcile conflicts."

Note: prompts sent to Codex/Gemini are expected to be English for consistency (you can still chat with Claude in any language).

The routing/checkpoint rules live in skills/coordinating-multi-model-work/.

• Built-in multi-model routing via MCP tools (mcp__codex__codex, mcp__gemini__gemini).
• CP checkpoints (CP1/CP2/CP3) added to enforce evidence-driven collaboration.
• Skill set changes (additions/renames) for the CCG workflow.
• Different marketplace source: install from https://github.com/BryanHoo/superpowers-ccg.
