Community Builder is an agent skill that guides community-led growth across nine disciplines—from strategy and platforms to onboarding, engagement, ambassadors, metrics,

About

Community Builder is an agent skill that structures how solo and indie founders grow through communities: strategy and positioning, picking the right platform, onboarding for first-value moments, rituals and events, UGC, ambassador programs, health metrics, moderation, and DevRel basics. It treats community as a growth channel with explicit impact tiers so you invest first in strategy, platform fit, and activation before scaling programs. Use it when you are standing up a Discord or Slack space, reviving a dead forum, or layering community-led growth on top of SaaS distribution. The skill is advisory and sectional—nine disciplines—rather than automating posts or installs. It pairs well with launch distribution planning and later analytics reviews when you measure engagement ROI. Builders with no audience yet may still use the strategy and platform sections during Validate to decide if community fits their motion.

  • 9 community capability sections from strategy through DevRel
  • CRITICAL-impact coverage for strategy, platform selection, and member onboarding
  • Platform comparison patterns for Discord, Slack, Circle, Discourse, and alternatives
  • Engagement programs, UGC systems, and ambassador or champion tier design
  • Metrics, moderation, governance, and developer-relations guidance in one playbook

What it does

Design and run community-led growth—platform choice, onboarding, engagement rituals, ambassadors, metrics, and moderation—for a product without a dedicated community team.

Who is it for?

Best when you're launching or reviving a member community with limited moderation bandwidth.

Skip if: Pure performance-marketing or SEO-only growth with no intent to host members, or enterprises with fully staffed DevRel and community ops already running.

When should I use this skill?

Planning community-led growth, selecting a community platform, designing onboarding or ambassador programs, or improving engagement and community health metrics.

What you get

You get a structured community plan across nine sections—strategy, platform, onboarding, programs, content, ambassadors, metrics, moderation, and DevRel—ready to implement on your chosen stack.

  • Community strategy and platform recommendation
  • Onboarding and engagement program outlines
  • Metrics and moderation/governance checklist

By the numbers

  • 9 community capability sections (strategy through DevRel)
  • 3 sections marked CRITICAL impact: strategy, platform, onboarding

The 1-9-90 Rule

In most communities:

  • 1% create content (Creators)
  • 9% engage with content (Contributors)
  • 90% consume content (Lurkers)

Goal: Move people up the engagement ladder, not force everyone to create.

Anti-Patterns

  • Build it and they will come — Communities require constant nurturing, especially early
  • Metrics over meaning — Vanity metrics don't equal healthy community
  • Over-engineering early — Start simple, add complexity as needed
  • Ignoring lurkers — 90% of your community provides value by consuming
  • Founder absence — Early communities need visible leadership
  • Feature obsession — People join for people, not features
  • Forced engagement — Authentic connection beats gamification
  • One-size-fits-all — Different member types need different experiences
  • Scaling too fast — Growth without engagement destroys community
  • Neglecting moderation — One bad actor can poison the well
