A fenced bash/python block in SKILL.md carries a natural-language imperative — "now run this", "execute the following command" — directing the agent to execute the fenced content. What looks like documentation becomes an executable payload the agent may run without ever asking you.

The primary manifest — the file an agent reads to learn what this artifact does.
A self-improving Claude Code skills plugin. It discovers skills from GitHub, ranks them against a profile built from your local Claude Code history, installs them, and uses its own skills to validate and evolve the collection.
Everything is SKILL.md files — no build system, no scripts.
Inside Claude Code:
/plugin marketplace add JasonLo/skill-sommelier
/plugin install skill-sommelier@skill-sommelierDon't have Claude Code yet, or want a one-liner that also sets up companions like gh and uv?

The plugin install itself happens inside Claude Code — that's the only way to add a plugin.
Skills are namespaced as /skill-sommelier:<name>. Update with /skill-sommelier:ss-update or /plugin marketplace update. Uninstall via /plugin uninstall skill-sommelier@skill-sommelier (or scripts/uninstall.sh for a guided cleanup).
/skill-sommelier:ss-skill-discoverOn first run it builds your developer profile from local Claude Code history, then finds and installs skills tailored to your stack. Pass my profile to refresh the profile alone.
