yousiki's Claude Code Plugins
A personal, curated marketplace of Claude Code plugins.
Language servers, MCP servers, hooks, and workflow helpers — each tool boots through a runtime fallback chain (bunx / uvx and friends), so nothing has to be installed globally on the host.

Highlights
- Zero host install. Each plugin launches through a fallback chain — JS/TS via
bunx → pnpm dlx → npx, Python via uvx → pipx run.
- Always fresh. Every invocation resolves the package on demand from the registry; no stale global binaries to babysit.
- Heterogeneous. LSPs, MCP servers, and hooks live side by side; slash commands and agents will land as I adopt them.
- Self-contained. One folder per plugin, metadata-only — no vendored binaries, no submodules.
- Opinionated. Only tools I personally use day to day; each one is battle-tested in my own workflow before shipping.
Plugins
Grouped by plugin kind. All plugins live under plugins/ and are registered in .claude-plugin/marketplace.json.
