Claude Plugins

Production-ready plugins for Claude Code and Claude Desktop. Financial reporting, budgeting, cost allocation, and country-specific tax compliance — all open source. Designed for Artifi, adaptable to any workflow.

Quick Install

Clone the plugin repository and add any plugin to your Claude project:

$ git clone https://github.com/ar-ti-fi/plugins.git

Each plugin is a self-contained directory with skills, commands, and reference files. Copy the plugin folder into your project's .claude/ directory, or follow the README in each plugin for specific setup instructions.

Built for Artifi, open for everyone. These plugins are designed to work out-of-the-box with the Artifi MCP server for full automation. You can also download and adapt them to your own needs — the skills, commands, validation logic, and reference data (tax formulas, report structures, XBRL taxonomies) are all yours to customize.
