## About the Project

Magma is a prompt development environment designed for working with coding agents like Claude Code, Codex, Gemini CLI, OpenCode and similar AI-powered development tools. While these tools are primarily designed for software development, they are increasingly used for a broader range of knowledge work tasks, making Magma useful beyond just coding.

At its core, Magma provides a knowledge base system built on Obsidian-compatible markdown documents that enables rapid composition of prompts through transclusions. This allows you to build reusable prompt libraries where complex prompts are assembled from smaller, well-defined pieces of knowledge.

_Read on in the [User Guide](https://hexdocs.pm/magma/01-introduction.html)_

## Installation

### Homebrew (macOS & Linux)

```bash
brew tap marcelotto/tap
brew install magma
```

### Manual Installation

Download the latest release for your platform from the [Releases page](https://github.com/marcelotto/magma/releases).

Place the binary in your PATH (e.g., `/usr/local/bin/`):

```bash
chmod +x magma_macos_arm
mv magma_macos_arm /usr/local/bin/magma
```

### Verify Installation

```bash
magma version
```

## Quick Start

Initialize a new vault:

```bash
magma init
```

Then open the vault folder in Obsidian. See the [User Guide](https://hexdocs.pm/magma/01-introduction.html) for detailed usage instructions.

## Features

- **Transclusion resolution system** for rapid prompt composition from existing knowledge fragments
- **Session-based workflow** for iterative conversations with coding agents that maintain conversation history
- **Coding agent integration** with support for file reference syntax (`@"path/to/file.md"`)
- **Organized vault structure** with templates for different document types (Prompts and Sessions)
- **Clean separation** of prompts, responses, and notes within Session documents
- **Obsidian integration** with adaptability to many use cases through Obsidian's vast plugin ecosystem

## Known Limitations
