Included Skills1

mumoskills/mumo/SKILL.md

Runs a multi-model deliberation across models from different labs (Claude, GPT, Gemini, Grok, DeepSeek, Kimi, and more) via mumo's MCP server, returning full responses plus typed cross-model reactions. Use when independent perspectives are needed on architecture/product decisions, design and plan review before implementation, pre-launch pressure tests, tradeoffs with multiple defensible framings, or explicit user requests for a mumo panel. Especially valuable for pre-implementation review of anything touching auth, security, tokens, payments, data exposure, or migrations. Requires a mumo platform API key exported as MUMO_API_KEY.

Useful before commitment-grade decisions: architecture, design review, pre-commit review on risky diffs, stuck debugging, or anything where the cost of being wrong outweighs the cost of deliberation.",
