Overview
Open-source framework for augmenting humans using AI
Pros
- ✓ Unique 'pattern' system — pre-built, community-sourced prompts for common tasks
- ✓ CLI-first design enables powerful shell pipelines with AI processing
- ✓ Growing library of 200+ patterns for summarization, analysis, coding, and more
- ✓ Easy to create and share custom patterns for your specific workflows
Cons
- ✗ CLI-only — no GUI for users who prefer visual interfaces
- ✗ Pattern quality varies in the community library — requires curation for production use
- ✗ Less suitable for multi-step workflows requiring state management
Key Features
- 🧵200+ Community Patterns: Pre-built, shareable prompt templates for summarization, code generation, analysis, and writing. Mix-and-match patterns or create custom ones for your workflow.
- ⌨️Unix Pipe-First Architecture: Process text through AI directly in shell pipelines. Pipe CLI outputs to Fabric patterns, enabling automation without leaving the terminal.
- 🔀Pattern Composition System: Chain multiple patterns sequentially to build complex AI workflows. Process outputs from one pattern as inputs to another for multi-step augmentation.
- 🛠️Multi-Model Backend Support: Route patterns to different LLM providers (OpenAI, Anthropic, local models). Switch providers per-pattern without rewriting prompts.
- 📦Minimal Dependencies: Lightweight Go-based CLI with no heavy frameworks. Fast startup times and low resource overhead for frequent command-line invocation.
