dm-lang

Dark Matter Marketplace

A personal Claude Code plugin marketplace for workflows, skills, and agents that I use daily.

Disclaimer

This is my personal repo. It reflects my workflows, preferences, and experiments. YMMV.

• Changes frequently, often without notice
• Often in an experimental state
• May contain half-baked ideas alongside polished tools
• Not designed for general consumption, but you're welcome to browse

If something here is useful to you, great. If not, no worries.
