+### AI Coding Skills
+
+Both `init` and `upgrade` install the **pattern-author** skill into your pattern repository. This skill teaches AI coding assistants how to work with Validated Patterns — including the values file structure, operator subscriptions, secrets framework, and hub/spoke configuration.
+
+The skill is installed for both [Claude Code](https://docs.anthropic.com/en/docs/claude-code) and [Cursor](https://cursor.com/) using the [Agent Skills](https://cursor.com/docs/skills) open standard. The same skill files work in both tools. Any existing skills or configuration you have in your `.claude/` or `.cursor/` directories are left untouched.
+
+To use the skill, open your pattern repository in Claude Code or Cursor and ask the assistant to help with pattern authoring tasks — for example, adding an operator, configuring secrets, or setting up a spoke cluster.
