8gnc

The free, MIT-licensed skill plugins from Branded Mayhem Collective — brand strategy, product strategy, content, SEO, conversion, sales — installable in one command into Claude Code, Codex, Cursor, or any agent that reads SKILL.md folders.

npx @8gnc/skills                         # list the catalog
npx @8gnc/skills add brandprint-engine   # install into ./.claude/skills
npx @8gnc/skills add all -g              # everything, into ~/.claude/skills
npx @8gnc/skills add seo-visibility-toolkit --into ~/.codex/skills

The catalog of record is the contraband marketplace manifest — the same file Claude Code's /plugin marketplace reads — so this CLI can't drift from it. Each plugin is its own public repo; add downloads the repo and copies its skills/ folders. No account, no telemetry, no runtime dependencies.

| Plugin | What it is | |---|---| | brandprint-engine | Six-layer brand strategy chain + deep-research engine → a consulting-grade Brand Strategy & Competitive Positioning report | | productprint-engine | Six-layer product strategy chain: Playing-to-Win cascade, Now/Next/Later roadmap, adversarial pre-mortem | | content-creative-lab | Eight-skill content lab: voice profiling, humanization, narrative structure, focus-group simulation | | seo-visibility-toolkit | DataForSEO automation, local-services SEO matrix, AI-agent-readiness audits, AI-commerce data density | | conversion-architecture | Neuro-design playbook, UX/UI choice architecture, fairness-anchor pricing ladder | | sales-accelerator | Pitching pivot, outreach diagnosis, sales-simulator practice arena |
