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/skillsThe 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.
