Skills

Free skills for coding agents.

An agent skill is a saved set of instructions your coding agent follows for a particular job. These are the ones I’ve made and use, free and open to read before you run them.

Launch readiness.

You point it at an app you’ve built and it tells you what’s still missing before other people arrive. It runs your project’s own checks and a few established tools, reads the code for the things that get forgotten, asks you the handful of questions no tool can answer, and writes a report: what’s ready, what to fix first and what it couldn’t check. Every fix comes with a prompt you can paste into your agent.

It asks before installing anything, never prints a secret, changes nothing in your project, and won’t tell you your app is secure. Fifteen sections, and the ones that don’t apply to your project are skipped:

  • It installs, builds and runs
  • Secrets and dependencies
  • Sign-in and accounts
  • Supabase, or another backend service
  • Payments
  • Paid external and AI services
  • Product completeness
  • Phones, browsers and accessibility
  • Speed
  • Being found and shared
  • Privacy and user data
  • Knowing when it breaks, and getting back
  • Ownership and release
  • Mobile apps
  • Code health

It covers React web apps, Supabase, Node backends and React Native or Expo. It’s new: the README says which parts have been run against real projects and which haven’t, so you can judge what to trust.

If you’d rather learn to make your own, the last part of Getting Started with Coding Agents turns a routine you keep repeating into a skill, in Claude Code and in Codex.
