A Claude Code plugin that bundles six skills, each one a slash command: /backend, /uiux, /security, /checkprod, /research and /explain. Every skill lives in its own folder, so any one of them can be copied out and used alone.
The skills work from written rules rather than taste. /uiux builds against sixteen hard rules and can audit a live site as a first time visitor, /backend applies eighteen rules on auth, queries and background jobs and can load test a service you own, /checkprod grades forty launch items and backs every pass with proof, and /research checks each citation against a registry before trusting it.
Each skill ships with reference files, helper scripts and an eval suite that checks it triggers when it should and stays quiet when it should not. The whole set installs with two commands from the plugin marketplace.
Outcome: Open source, 6 skills.
