| 5 | |
| 6 | 28 plugins and MCP servers for Claude Code — parallel exploration, iterative refinement, binary reverse engineering, structured decision-making, and more. |
| 7 | |
| 8 | Built by the team at [2389](https://2389.ai). These are the tools we use every day. |
| 9 | |
| 10 | **Browse the marketplace:** https://2389-research.github.io/claude-plugins |
| 11 | |
| 12 | ## Quick Start |
| 13 | |
| 14 | Install any plugin in **any agent** (Claude Code, Cursor, Codex, …) with [vercel-labs/skills](https://github.com/vercel-labs/skills): |
| 15 | |
| 16 | ```bash |
| 17 | npx skills add 2389-research/simmer |
| 18 | ``` |
| 19 | |
| 20 | Or natively in Claude Code: |
| 21 | |
| 22 | ```bash |
| 23 | # Add the marketplace, then install any plugin |
| 24 | /plugin marketplace add 2389-research/claude-plugins |
| 25 | /plugin install simmer@2389-research |
| 26 | ``` |
| 27 | |
| 28 | > The 4 MCP servers (journal, socialmedia, slack-mcp, agent-drugs) install via Claude Code only — they ship no skills for npx. |
