+# Documentation Autowriter
+
+When to use this skill
+
+- Use whenever you add new components, agents, or stores and want docs updated for reviewers.
+- Triggered by prompts like "update README" or "generate architecture overview".
+
+Instructions
+
+1. First Step: Scan `src/components/` and `src/stores/` to build a component map and store summary.
+
+2. Second Step: Render `README.md` with development steps, demo instructions (how to use Copilot CLI agents), and a brief feature summary.
+
+3. Third Step: Produce `ARCHITECTURE.md` documenting Atomic Design layout, store relationships, and agent/skill list for the judges.
+
+Examples
+
+- README includes: setup, run, test, demo CLI steps (`gh copilot ask "Find endorsers for my paper"`).
+
+Notes
+
+- Keep automated docs human-editable and include pointers to extend the output (how to add a new component/module).
