28 plugins and MCP servers for Claude Code — parallel exploration, iterative refinement, binary reverse engineering, structured decision-making, and more.
Built by the team at 2389. These are the tools we use every day.

Quick Start
Install any plugin in any agent (Claude Code, Cursor, Codex, …) with vercel-labs/skills:
npx skills add 2389-research/simmer
Or natively in Claude Code:
# Add the marketplace, then install any plugin
/plugin marketplace add 2389-research/claude-plugins
/plugin install simmer@2389-research
The 4 MCP servers (journal, socialmedia, slack-mcp, agent-drugs) install via Claude Code only — they ship no skills for npx.
