## Suggested prompts
### New install

```text
I downloaded a skill package from Yavira. Read SKILL.md from the extracted folder and install it by following the included instructions. Tell me what you changed and call out any manual steps you could not complete.
```
### Upgrade existing

```text
I downloaded an updated skill package from Yavira. Read SKILL.md from the extracted folder, compare it with my current installation, and upgrade it while preserving any custom configuration unless the package docs explicitly say otherwise. Summarize what changed and any follow-up checks I should run.

const content = await web_fetch("https://example.com");

### Rung 2: JS-rendered page

### Rung 3: Cloud browser (BrowserCat)

const { chromium } = require('playwright');
const browser = await chromium.connect('wss://api.browsercat.com/connect', {
  headers: { 'Api-Key': process.env.BROWSERCAT_API_KEY }
});

### Rung 4: CAPTCHA bypass (Browserless)

const { chromium } = require('playwright');
const browser = await chromium.connectOverCDP(
  \`wss://production-sfo.browserless.io?token=${process.env.BROWSERLESS_TOKEN}\`
);
// CAPTCHA handled automatically

### Cost Optimization

Start low — Always try Rung 1 first
Cache results — Don't re-fetch unnecessarily
Batch requests — One browser session for multiple pages
Check success — Only climb if lower rung fails
