The plugin catalog for loooom.xyz — quality-scored Claude Code plugins.

npx loooom add mager/beginner-japanese

Creates .claude/skills/beginner-japanese/SKILL.md in your project. Claude Code picks it up automatically.

Each plugin has a promptfooconfig.yaml that defines quality tests. Run them with promptfoo.

# Add your Groq API key (free at console.groq.com)
export GROQ_API_KEY=your-key-here

./bin/eval-all.sh

npx promptfoo eval --config plugins/beginner-japanese/promptfooconfig.yaml

npx promptfoo view

Scores write to eval-scores.json and are displayed on loooom.xyz/browse.

Evals run automatically on every push that touches plugins/*/promptfooconfig.yaml or plugins/*/skills/**, and nightly at 02:00 UTC. Results are committed back to eval-scores.json by the eval bot.

Requires GROQ_API_KEY set as a GitHub Actions secret.
