+name: "Prettier Automator"
+description: "Generates Prettier configuration and optional Husky + lint-staged hooks to auto-format code on commit."
+triggers:
+  - "setup prettier"
+  - "create .prettierrc"
+  - "add husky lint-staged"
+---
+
+# Prettier Automator
+
+Purpose
+- Create a consistent Prettier config and add scripts/hooks to keep code formatted automatically.
+
+Example prompts
+- "create .prettierrc and format script"
+- "add husky pre-commit to run prettier via lint-staged"
+
+Example .prettierrc
+```json
+{
+  "printWidth": 100,
+  "tabWidth": 2,
+  "singleQuote": true,
+  "trailingComma": "all",
+  "semi": true
+}
+```
+
+Suggested package.json additions
+```json
+"scripts": {
+  "format": "prettier --write \"src/**/*.{ts,tsx,js,jsx,css,scss,md}\""
+},
+"lint-staged": {
+  "src/**/*.{js,jsx,ts,tsx}": [
+    "prettier --write"
+  ]
+}
+```
+
+Husky notes
+- `npx husky-init && npm install` then `npx husky set .husky/pre-commit "npx lint-staged"` to hook formatting.
+- This agent suggests commands and scaffold snippets; applying hooks requires running the commands locally.
