What problem does it solve? Building and growing an online community is hard to do systematically: teams struggle to pick the right platform, activate lurkers, retain members, and turn engaged users into advocates. This Skill provides structured playbooks, health metrics, and community models to design, launch, and scale communities that drive retention, word-of-mouth, and support deflection. ## Core Features & Use Cases - Goal-Based Playbooks: Step-by-step guides for launching from zero, growing an existing community, building ambassador programs, and running community-led support. - Platform & Model Selection: A comparison guide for Discord, Slack, Circle, Reddit, Facebook Groups, and forums, plus five community models (Support-Driven, Product-Development, Education, Founder-Led) with a scaling-phase role framework in references/community-models.md. - Health Diagnostics: Concrete metrics (DAU/MAU ratio, new member post rate, thread reply rate) and warning signs to audit a stalled community. - Use Case: A B2B SaaS team with 40 members and only 3 active posters asks for help; the Skill diagnoses a new-member activation problem and produces a new member journey, seeded conversations, and a weekly ritual calendar. ## Quick Start Ask the assistant to design a 90-day launch plan for a new Discord community for your product's users.
