librarii
Manage AI agent skills and map your business processes — all from a single VS Code sidebar.
What is librarii?
librarii is a marketplace for AI agent skills and agents. It lets you install, customize, and compose skills that your AI assistants (Claude Code, Gemini CLI, Cursor…) read directly from your workspace. It also ships with a visual process editor so you can map business workflows alongside the skills that support them.
Features
- AI catalog — browse a curated registry of skills and agents. Install with one click.
- Customize without forking — override specific sections of a
SKILL.md (replace, append, prepend) without modifying the source.
- Create your own skills — author local custom skills directly from the sidebar.
- Agents — install bundled agents that come with their dependent skills.
- Process editor — visual builder for
.process.json maps: swimlanes, sub-processes, step-level skills and deliverables, zoom/pan, snap-to-grid.
- Deliverables — manage project artifacts (title, description, link) and attach them to process steps.
- Auto-install from settings — pre-install skills and agents at workspace open via
settings.json.
- Multi-agent compatibility — writes to
.librarii/ and creates the symlinks Claude Code and Gemini CLI expect.
Getting started
- Install the extension
- Open a workspace folder
- Click the librarii icon in the activity bar
- Browse the catalog, install a skill, start mapping a process
The librarii registry is a public GitHub repo — no login required. If you're already signed in to GitHub in VS Code, the extension silently reuses that session to lift the API rate limit; it never prompts.
Auto-install skills and agents
Pre-configure skills/agents for a project in .vscode/settings.json (or your user settings):
{
"librarii.autoInstall.skills": ["code-reviewer", "test-writer"],
"librarii.autoInstall.agents": ["refactorer"]
}
On workspace open the extension installs anything missing. If you later uninstall an item, it won't be re-installed — your choice is remembered.
