9 Agent Skills Repos I Tried (And Now I Can’t Stop Using Them)

Source: Joe Njenga, 9 Agent Skills Repos I Tried (And Now I Can’t Stop Using Them) (Medium / AI Software Engineer, 2026-04-08)

Key takeaways

Curated review of nine community skill repositories for Claude Code.
Njenga’s framing: “most look impressive until you actually try them. A handful are genuinely useful.”
Saves you the cost of evaluating dozens of repos yourself — Njenga has already tested them.
Pair with Rezvani’s github.com/alirezarezvani/claude-skills (220+ skills, separate reference).

Why this is worth reading

The Claude Code skill ecosystem is growing fast. Most community skill repos are impressive-looking but shallow on test. Njenga’s article filters.

The value isn’t just the list — it’s the honest verdict on each. A repo that “looks amazing” but “doesn’t actually work in production” is identified explicitly.

How to use the list

Read Njenga’s article for the nine repos + verdicts
Install the ones relevant to your stack (TypeScript, React, testing, etc.)
Compare against OMC’s built-in skills if you’re running OMC
Don’t install everything — skill bloat works against you (see skill-bloat lesson)

Note on skill bloat

From CLAUDE.md lessons learned: “More skills doesn’t mean better output. Community data shows 40/47 tested skills made output worse by adding tokens and narrowing responses. Build your own for critical workflows.”

Translation: be selective. Njenga’s curated nine is a better starting point than installing everything you can find.
