The main monitor (reddit-api-monitor.ts) runs automatically as a cron job. To configure the schedule:

1. Go to the Val Town web UI
2. Find the reddit-api-monitor.ts file
3. Edit the cron schedule as needed (recommended: every 15-30 minutes)

GET /test-reddit-api.ts?action=help

GET /test-reddit-api.ts?action=auth&client_id=151sZ8h5TaHVZGZZn0rOhA

GET /test-reddit-api.ts?action=test&client_id=151sZ8h5TaHVZGZZn0rOhA&subreddit=lovable

GET /test-main-monitor.ts?action=run

GET /test-slack.ts?action=simple    # Send simple test message
GET /test-slack.ts?action=reddit    # Send mock Reddit post notification  
GET /test-slack.ts?action=error     # Send mock error notification
GET /test-slack.ts?action=help      # Show usage information

GET /test-reddit-api.ts?action=reset

When matches are found, you'll receive a Slack message with:

• Header: 🚨 Reddit Monitor Alert: X new matching posts in r/subreddit
• Rich Attachments for each matching post including:
  • Post title (clickable link to Reddit)
  • Matched keywords
  • Author information
  • Score and comment count
  • Publication date
  • Content preview
  • Subreddit footer

Webhook URL: https://hooks.slack.com/services/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

• Post Titles: Full text search for keywords
• Post Content: Self-text content of posts
• Frequency: Based on cron schedule (configurable)
• Scope: New posts since last check

• Case-insensitive matching
• Partial word matching (e.g., "auth" matches "authentication")
• Multiple keyword detection per post
• Configurable keyword list

Recent Test Results: Found matches for "signin" in r/lovable posts

Edit the CONFIG object in reddit-api-monitor.ts:

const CONFIG: MonitorConfig = {
  subreddit: "lovable",
  keywords: ["auth", "authentication", "login", "signin", "signup", "oauth", "jwt", "token", "YOUR_NEW_KEYWORD"],
  lastChecked: 0
};

Change the subreddit in the CONFIG object:

const CONFIG: MonitorConfig = {
  subreddit: "your_target_subreddit",
  keywords: ["your", "keywords", "here"],
  lastChecked: 0
};

Modify the limit parameter in the fetchSubredditPosts function call:

const posts = await fetchSubredditPosts(CONFIG.subreddit, 50); // Check 50 posts instead of 25
