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
