# 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 reddit

Subsequent 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]
    camofox snapshot [tabId]
    camofox scroll down [tabId] --amount 500
    camofox snapshot [tabId]
    camofox get-links [tabId]

## 4. Browse Subreddit

    camofox navigate https://old.reddit.com/r/test [tabId]
    camofox snapshot [tabId]
    camofox click [eN] [tabId]
    camofox snapshot [tabId]

Old Reddit has simpler HTML structure — easier to parse post listings.

## 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 snapshot [tabId]
    camofox click [eN] [tabId]
    camofox snapshot [tabId]

Why eval? Reddit's old textarea causes Internal Server Error when filled via browser automation type. Setting textarea.value via JavaScript works reliably.

## 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]
    camofox snapshot [tabId]
    camofox type [eN] "Post content with markdown." [tabId]
    camofox snapshot [tabId]
    camofox click [eN] [tabId]
    camofox wait navigation [tabId] --timeout 5000
    camofox snapshot [tabId]

## 7. Reply to Comment (Old Reddit)

    camofox navigate https://old.reddit.com/r/test/comments/POST_ID/ [tabId]
    camofox snapshot [tabId]
    camofox click [eN] [tabId]
    camofox snapshot [tabId]
    camofox eval "const tas = document.querySelectorAll('.usertext-edit textarea'); const rb = Array.from(tas).find(t => t.offsetParent !== null && t.value === ''); if (rb) { rb.value = 'Your reply'; rb.dispatchEvent(new Event('input', {bubbles: true})); rb.dispatchEvent(new Event('change', {bubbles: true})); }" [tabId]
    camofox snapshot [tabId]
    camofox click [eN] [tabId]
    camofox snapshot [tabId]

## 8. Upvote / Downvote

    camofox snapshot [tabId]
    camofox click [eN] [tabId]

Vote buttons appear as arrow icon refs in the snapshot.

## 9. Session Management

    camofox session save "reddit-session" --user reddit
    camofox session load "reddit-session" --user reddit
    camofox session list
    camofox session delete "reddit-session"

## 10. Rate Limiting

- Wait 2+ minutes between comments/replies
- Wait 10+ minutes between posts for new/low-karma accounts
- Add delays: `camofox wait networkidle [tabId] --timeout 3000`
- Higher karma accounts have relaxed limits

## 11. Anti-Detection

- CamoFox anti-detection fully effective on Reddit (0 CAPTCHAs in 50+ operations)
- Reddit serves ads to CamoFox = treats as real user
- Use consistent userId ("reddit") across sessions
- Do NOT clear cookies between actions
- No special proxy or fingerprint settings needed

## 12. Platform Selection

| Action | Platform | Reason |
|--------|----------|--------|
| Login | Manual only | reCAPTCHA Enterprise |

| Reply | old.reddit.com | Plain HTML forms |

| Browse | Either | Both work |
| Vote | Either | Both work |

## 13. Troubleshooting

| Issue | Cause | Fix |
|-------|-------|-----|
| Login CAPTCHA | reCAPTCHA Enterprise | Use saved sessions |
| Post CAPTCHA on old Reddit | reCAPTCHA v2 | Use new Reddit |
| Comment 500 error | type on old Reddit | Use eval with textarea.value |
| Text doubled | Lexical editor bug | Use eval for input |
| Rate limited | Rapid actions | Wait 2+ minutes |
| SPA link fails | Reddit SPA | Use camofox navigate |
| Session expired | Cookies expired | Re-login and save |

## 14. Complete Example

    #!/bin/bash
    USER="reddit"
    SESSION="reddit-session"

    TAB=$(camofox open https://www.reddit.com --user $USER --format json | jq -r '.tabId')
    camofox session load $SESSION --user $USER

    camofox navigate https://old.reddit.com/r/test $TAB

    camofox eval "const ta = document.querySelector('.usertext-edit textarea'); ta.value = 'Automated via CamoFox CLI'; ta.dispatchEvent(new Event('input', {bubbles: true})); ta.dispatchEvent(new Event('change', {bubbles: true}));" $TAB

    camofox session save $SESSION --user $USER
    camofox close --user $USER
