-## Dependency
+## Install Or Update
 
-This skill depends on the workspace `web-automation` skill and its CloakBrowser runtime.
+Run these commands from the `stef-openclaw-skills` repo checkout:
+
+```bash
+cd ~/.openclaw/workspace/projects/stef-openclaw-skills
+git pull --ff-only
+rsync -a --delete \
+  --exclude node_modules \
+  --exclude dist \
+  --exclude coverage \
+  --exclude tmp \
+  --exclude out \
+  --exclude '*.log' \
+  --exclude '*.real.html' \
+  skills/amazon-shopping/ \
+  ~/.openclaw/workspace/skills/amazon-shopping/
+cd ~/.openclaw/workspace/skills/amazon-shopping
+npm ci
+```
+
+Use the same sequence for a first install and for updates. `rsync --delete` keeps the active skill identical to the repo copy while preserving generated dependencies through the `node_modules` exclude. Always run `npm ci` after syncing because dependency changes are tracked through `package-lock.json`.
+
+## Setup Verification
+
+Verify the dependency skill, the active install, and OpenClaw discovery:
 
 ```bash
 openclaw skills info web-automation
 node "$HOME/.openclaw/workspace/skills/web-automation/scripts/check-install.js"
-```
-
-Setup or update the active `amazon-shopping` helper:
-
-```bash
 cd ~/.openclaw/workspace/skills/amazon-shopping
-npm ci
 npm run lint
 npm run typecheck
 npm test
+openclaw skills info amazon-shopping
 ```
 
+For a quick parser-only check that does not browse Amazon:
+
+```bash
+scripts/search-products 'USB-C charger under $30' --dry-run --json
+```
+
+For a live smoke after install or update:

 - It does not sign in, add to cart, purchase, access wishlists, submit reviews, crawl review pages, or bypass CAPTCHA/block pages.
 - It stops and reports a warning when Amazon returns a challenge, block, or disallowed robots path.
 - It uses default bounded operation: 15 results, 2 search pages, detail pages one at a time.
