Use when adding a plugin to the marketplace, or when authoring, editing, or re-rendering a scene under scripts/animations/scenes/ — including when a scene fails the render contract, the contrast gate, or the grid baseline.
Choose how to use this skill
You do not need every option. Choose the path your AI client supports. The stable page stays the same; versioned files are immutable.
1. Native installer
This listing has no registered native installer command. Use the complete package or source fallback below, depending on what your client supports.
Do not guess an installer command or replace an existing version without reviewing the diff.
2. Complete package recommended
Download the ZIP when available. It includes SKILL.md plus the references, security notes and version metadata.
No complete ProSkills package is published for this listing yet.3. Prompt-only
Copy the prompt above when the agent can read the stable page or when you want to adopt the workflow without installing a skill.
Need only the instruction file?
Download SKILL.md only if your client requires a single file. The complete ZIP is safer for a full installation because it preserves the references and release context.
No path installs or executes anything by itself. Your agent still needs access to the project files. Before updating, compare the installed version and review the diff.

2389 Research Claude Code Plugin Marketplace
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.
Browse the marketplace: https://skills.2389.ai
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.
