Connection Tester

Overview

This skill provides a quick and reliable way to test network connectivity to websites and services, with a default target of google.com for basic internet connectivity checks.

When to Use

Use this skill when:

  • •Testing internet connectivity
  • •Checking if a specific website or URL is reachable
  • •Diagnosing network connection issues
  • •Verifying HTTP/HTTPS endpoints are responding
  • •Measuring response times for web services

Workflow

Basic Connectivity Test (Google.com)

For a quick internet connectivity check, test connection to google.com:

python
# Using http_request tool
http_request(
    url="https://www.google.com",
    method="GET",
    timeout_seconds=10
)

Success indicators:

  • •Status code: 200
  • •Response received within timeout
  • •No connection errors

Test Custom URL

To test connectivity to a specific URL:

python
http_request(
    url="https://example.com",
    method="GET",
    timeout_seconds=30
)

Advanced Diagnostics

For more detailed network diagnostics, use command-line tools:

Using curl:

bash
curl -I -m 10 https://www.google.com

Using ping:

bash
ping -c 4 google.com

Using wget:

bash
wget --spider --timeout=10 https://www.google.com

Response Analysis

HTTP Status Codes

  • •2xx: Success - Connection working
  • •3xx: Redirect - Connection working, but URL redirected
  • •4xx: Client error - Connection working, but resource issue
  • •5xx: Server error - Connection working, but server problem
  • •Timeout/No response: Connectivity issue

Common Issues

  1. •Timeout: Network unreachable or server not responding
  2. •DNS Error: Domain name cannot be resolved
  3. •Connection Refused: Server not accepting connections
  4. •SSL Error: Certificate problem with HTTPS

Examples

Example 1: Quick Internet Check

User: "Test my internet connection" → Test https://www.google.com and report status

Example 2: Custom Endpoint

User: "Check if https://api.example.com is reachable" → Test the specified URL and report response details

Example 3: Multiple Tests

User: "Test connectivity to google.com and github.com" → Run tests for both URLs and compare results

Best Practices

  1. •Use appropriate timeouts: 10-30 seconds for most tests
  2. •Check both HTTP and HTTPS: Some sites may redirect
  3. •Consider rate limiting: Don't spam requests
  4. •Report meaningful info: Include status code, response time, and any errors
