Skills & Plugins

Author and import Claude Skills and Plugins. Sync an org manifest across every user.

Claude Skills

A Claude Skill is a bundle of instructions, allowed tools, and helper files that an agent can invoke. As of 5.0.0, NBI’s Skills tab is a top-level Settings tab visible in any mode (with a hint banner when Claude mode is off).

  • Author inline. Create a new Skill, edit its SKILL.md and helper files without leaving the lab.
  • Import from GitHub. Drop a github.com/owner/repo/tree/main/skills/<name> URL into the import dialog; NBI fetches the tarball, validates the bundle, and installs it under ~/.jupyter/skills/. Optional Track upstream checkbox surfaces a per-skill Sync button and a panel-level “Sync tracking skills”.
  • Org-managed manifest. Point NBI_SKILLS_MANIFEST at one or more YAML manifest files or URLs (comma-separated for multiple). NBI’s reconciler installs every Skill at startup and re-checks every 24h. Managed Skills are read-only in the UI — users can’t edit, rename, or delete them, and the reconciler restores any that get removed.

Claude MCP Servers

A separate top-level tab in 5.0.0 manages the user, project, and local-scope MCP entries Claude Code reads from ~/.claude.json and <project>/.mcp.json. Independent of the existing NBI MCP tab; the two never appear at the same time.

  • Per-workspace enable / disable. Toggle individual MCP entries on / off without removing them.
  • JSON-paste path. Paste a Claude / Cursor / VS Code MCP config blob; NBI parses, validates, and pre-fills the form.
  • Admin policy. NBI_CLAUDE_MCP_MANAGEMENT_POLICY=force-off hides the tab and 403s /claude-mcp/* routes.

Claude Plugins

Claude Plugins are install-and-go bundles published to marketplaces. NBI’s Plugins panel wraps the claude plugin CLI:

  • Install, uninstall, enable, disable. From a marketplace URL or a GitHub repo.
  • Marketplace add / remove. Manage which marketplaces are visible to Claude.
  • Marketplace picker. Browse the configured marketplaces inline; entries show source repo, version, and description.
  • Per-plugin Update button. Surfaces when a newer version is available upstream.
  • Project vs user scope. Plugins installed to a project root are isolated to that workspace.
  • Admin policies. NBI_CLAUDE_PLUGINS_MANAGEMENT_POLICY for the whole tab; NBI_ALLOW_GITHUB_PLUGIN_IMPORT for marketplace sources resolving as GitHub URLs.
