It includes 23 specialized tools—CEO, engineering manager, designer, QA, security auditor, release engineer—all invoked via slash commands, plus 8 power tools for planning, review, deployment, and security automation. Designed for founders and operators who still code; ships features 240× faster than traditional methods.

Who it is for

Technical founders, product-driven CTOs, and first-time Claude Code users who want structured, role-based AI collaboration instead of blank prompts. Also valuable for RevOps / automation-building operators learning to compose Claude agents and subagents.
