Reddit Automation Skill
Automate Reddit using CamoFox CLI anti-detection browser. All workflows verified on 2026-03-04 with zero CAPTCHAs triggered across 50+ operations.
1. Prerequisites
- CamoFox browser running:
camofox server status - A saved Reddit session (see Section 2)
- Install:
npm install -g camofox-browser
2. Authentication
Reddit login uses reCAPTCHA Enterprise — automated credential entry is blocked. Use session-based auth:
First time — login manually in CamoFox, then save:
camofox session save "reddit-session" --user redditSubsequent times — restore saved session:
camofox open https://www.reddit.com --user reddit
camofox session load "reddit-session" --user reddit
camofox navigate https://www.reddit.com [tabId]
camofox snapshot [tabId]Verify: username visible in snapshot confirms login.
Store credentials for reference:
camofox auth save reddit-main --url https://www.reddit.com --notes "Reddit account"3. Browse Feed
camofox open https://www.reddit.com --user reddit
camofox session load "reddit-session" --user reddit
camofox navigate https://www.reddit.com [tabId]

5. Comment on Post (Old Reddit)
IMPORTANT: Use eval to fill textarea — standard type causes 500 errors on old Reddit.
camofox navigate https://old.reddit.com/r/test/comments/POST_ID/ [tabId]
camofox snapshot [tabId]
camofox eval "const ta = document.querySelector('.usertext-edit textarea'); ta.value = 'Your comment'; ta.dispatchEvent(new Event('input', {bubbles: true})); ta.dispatchEvent(new Event('change', {bubbles: true}));" [tabId]

camofox click [eN] [tabId]

6. Create Post (New Reddit)
IMPORTANT: Use www.reddit.com — old Reddit has visible reCAPTCHA that blocks posting.
camofox navigate "https://www.reddit.com/r/test/submit?type=TEXT" [tabId]
camofox snapshot [tabId]
camofox type [eN] "Your Post Title" [tabId]
