A personal Claude Code plugin marketplace for workflows, skills, and agents that I use daily.
This is my personal repo. It reflects my workflows, preferences, and experiments. YMMV.
If something here is useful to you, great. If not, no worries.
# Add the marketplace
claude plugin marketplace add rbergman/dark-matter-marketplace
# Install plugins
claude plugin install dm-work@dark-matter-marketplace
claude plugin install dm-lang@dark-matter-marketplace
# ... or any other dm-* plugin
# Update after changes
claude plugin marketplace update dark-matter-marketplace
All components use the dm-* plugin prefix with semantic groupings:
| Plugin | Prefix | Example |
|---|---|---|
| dm-arch | Architecture patterns | dm-arch:solid-architecture |
| dm-team | Agent Teams patterns | dm-team:lead |
| dm-game | Game development | dm-game:game-design |
| dm-lang | Language expertise | dm-lang:typescript-pro |
| dm-tool | Tool design patterns | dm-tool:agent-dx-cli |
| dm-work | Workflow tools | dm-work:orchestrator |
Commands use /dm-work:command format (e.g., /dm-work:rotate).
