Looplia Core
Skills-first agentic workflow CLI — compose AI skills and workflows for any task.
Looplia Core is an agentic workflow platform powered by the Claude Agent SDK. It provides a skills-first architecture where workflows declare which skill to execute and provide natural language missions, letting Claude determine the best approach.
Current focus: Content writing workflows (summarization, idea generation, writing kit construction)
Vision: A universal CLI for AI-powered workflows — one tool, many domains, powered by composable skills.

Features
- Skills-First Architecture - Workflows declare skills + missions, not rigid agent definitions
- Skill Registry System - shadcn/ui-inspired registry for skill discovery and installation
- Selective Plugin Loading - Only load skills required by workflow (reduced context usage)
- Third-party Skills - Install community skills via git clone from marketplaces
- Marketplace Integration - 56+ skills installed by default (Anthropic + ComposioHQ)
- Per-Step Orchestration - One workflow step → one skill-executor call → multiple skills
- Workflow-as-Markdown - YAML frontmatter + markdown documentation
- Sandbox Isolation - Each run in
sandbox/{id}/inputs/outputs/logs/
- Validation-Driven - Deterministic script-based output validation
- Two-Plugin Model - Separate infrastructure (core) from domain logic (writer)
- Streaming TUI - Real-time progress with tool execution display
- Smart Continuation - Resume workflows via
--sandbox-id
- TypeScript - Full type safety with Zod schemas
Quick Start
# 1. Install dependencies
bun install
# 2. Build the project
bun run build
# 3. Initialize workspace (creates ~/.looplia/ with plugins)
bun run apps/cli/dist/index.js init --yes
