A tiny catalog with four plugins, one of which is Strunk & White

What it does

This repo is a Claude Code plugin marketplace: essentially a marketplace.json catalog plus a README, pointing at four plugins you can install through Claude Code’s plugin system. The flagship is Superpowers, a core skills library covering TDD, debugging, and collaboration patterns, with commands like /brainstorm and /execute-plan. The other three are a writing guide built on Strunk’s 1918 Elements of Style, a plugin-development reference bundling 42+ official docs, and a private journaling MCP server with local semantic search.

The interesting bit

The marketplace itself is nearly all glue — the actual value lives in the separate plugin repos it indexes. The oddball entry is Elements of Style: shipping a 106-year-old style manual (~12k tokens) as a Claude Code skill is either charming or the most literal interpretation of “classic writing guidance” yet.

Key highlights

• Superpowers core: 20+ skills, planning commands, and a skills-search tool with SessionStart context injection
• Private Journal MCP: multi-section journaling with local embeddings-based search, dual project/user storage
• Plugin-dev plugin bundles 42+ official Claude Code docs and self-updates them
• Marketplace metadata is MIT; each plugin carries its own license

Caveats

• Four plugins is a small catalog — “curated” is doing heavy lifting
• Everything here is one author’s ecosystem, so quality and maintenance depend on a single maintainer

Verdict

Worth a look if you use Claude Code and want a one-stop index to the Superpowers skills library. If you’re hoping for a broad community marketplace, this is more personal shelf than app store.
