## About

# AI Registry for Agents (ARA)

ARA (pronounced: _ah-rah_) is a package registry and distribution system for AI development artifacts. It provides a standardized way to discover, share, and install reusable components that enhance AI assistants and development workflows.

ARA is a vendor-agnostic open standard — any AI coding tool can implement it, including Kiro, Claude Code, Cursor, VS Code Copilot, Windsurf, and others.

## Package Types

ARA supports the following package types:

| Type | Description |
|------|-------------|
| `agent` | AI assistant configurations with prompts, tools, and behaviors |
| `mcp-server` | Model Context Protocol servers that extend AI capabilities |
| `powers` | Bundles of MCP tools, steering files, and hooks |
| `steering` | Persistent project knowledge files that guide agent behavior |
| `skill` | Procedural knowledge via SKILL.md |
| `context` | Knowledge files, prompt templates, and reference materials |
| `agents-md` | AGENTS.md format for guiding coding agents |

Use the optional `platform` field to declare tool-specific installation targets (e.g., `"platform": "kiro"`).
