Web Browsing Skill

Automatic fallback mechanism for web research.

CRITICAL: Tool Availability

NEVER check mcps folder to verify tool existence. Tools are ALWAYS available - just call them directly:

```
WebFetch
```
- Cursor built-in fetch tool (fastest)
```
cursor-browser-extension
```
- Cursor built-in browser
```
user-chrome-devtools
```
- Chrome DevTools (alternative)

Fallback Chain

1. WebFetch (fast, preferred)
   ↓ fails/error
2. Browser MCP (cursor-browser-extension)
   ↓ captcha/block
3. ai_interaction (request user help)

Step 1: WebFetch (Default)

WebFetch url="https://example.com"

Continue to Step 2 if:

HTTP error (4xx, 5xx)
Content empty or truncated
Authentication required
Rate limited

Step 2: Browser MCP

Use

cursor-browser-extension

MCP tools directly:

1. browser_navigate → target URL
2. browser_snapshot → get page content
3. browser_take_screenshot → visual reference (if needed)

Alternative:

user-chrome-devtools

if cursor-browser-extension fails.

Continue to Step 3 if:

Captcha detected
Bot check / "verify you're human"
Login required
Cloudflare/DDoS protection
Page content not loading

Step 3: User Assistance

CRITICAL RULES:

NEVER make autonomous decisions (e.g., switching to DuckDuckGo when Google blocked)
NEVER bypass user by trying alternative search engines/sites without asking
ALWAYS inform user and wait for instruction via ai_interaction

Call

ai_interaction

tool with message:

"Browser bị chặn bởi [captcha/bot check/login].
URL: [url]
Cần bạn:
1. Mở browser manual
2. Bypass protection
3. Báo lại khi xong để tôi tiếp tục

Hoặc bạn muốn thử [alternative option]?"

Then wait for user confirmation via ai_interaction before retrying.

Detection Patterns

Captcha/Block Indicators

"verify you are human"
"captcha"
"cloudflare"
"access denied"
"please wait while we verify"
Blank page with only scripts
HTTP 403, 429, 503

Success Indicators

Meaningful content returned
Expected HTML structure
No error messages

Best Practices

Always try WebFetch first - fastest option
Check response quality - not just HTTP status
Don't spam retries - wait between attempts
Be transparent - tell user what's happening
Save useful content - don't re-fetch unnecessarily

Integration with ai_interaction

When user helps bypass protection:

User completes manual action
User responds via ai_interaction
Agent retries with Browser MCP (cookies preserved)
