Keep the agent skills, MCP tools and prompts your team actually relies on in one place. Share them with the people you trust. Nobody else gets in unless someone inside lets them in.
Someone already inside sends you a code. Redeem it and your box is created, linked to the person who invited you.
Add the skills, MCP tools and prompts you use with Claude Code, Codex or Cursor. Pull them into any project with one command.
Open items to the people you invited, or keep them to yourself. Invite the developers you trust and the box grows from there.
Public marketplaces are full of half-finished skills you will never use. Your box only holds what you and your circle put in it.
Versioned SKILL.md bundles with their scripts and references. Install straight into a project.
Private MCP servers and tool configs, with the secrets kept out of the repo.
CLAUDE.md templates, review checklists and house rules that travel between projects.
Each item is yours alone until you share it. Nothing is ever public.
Every member gets a small number of invites. Each one is tied to your name, so the box stays a network of people who know each other.
