Reddit Commenter Skill

Reddit Comment Automation - From Exploration to Posting and Tracking

---

Required Tool: Playwright MCP

This skill uses Playwright MCP to interact with Reddit.

Main MCP Tools

MCP Tool	Purpose
browser_navigate	Navigate to Reddit pages
browser_snapshot	Capture page structure (accessibility tree)
browser_click	Click elements (comment box, buttons, etc.)
browser_type	Input text (comment content)
browser_wait_for	Wait for page loading

⚠️ Important Notes When Using Playwright MCP

• Minimize tokens: When calling MCP, don't pass entire conversation context—only concisely summarize the essential information needed for that action
• Direct navigation: Navigate directly to URLs with browser_navigate rather than clicking elements (prevents click errors, saves tokens)
• Concise instructions: Pass only minimal instructions like "Navigate to [URL]", "Click [element]", "Type: [text]"
• ⚠️ No screenshots: Do NOT use browser_take_screenshot. Always use only browser_snapshot for page verification (accessibility tree is sufficient and doesn't save files)

Execution Workflow

Step 1: Check Activity Status and Select Subreddit

1. Check today's date file in tracking/reddit/ folder
   → File name: YYYY-MM-DD.md (e.g., 2026-01-12.md)
   → If file doesn't exist, create new one referencing template.md

2. Check activity status table by subreddit:
   - How many comments posted in each subreddit today
   - Check subreddits under daily limit (3)
   - Check last comment time (minimum 5-10 minute intervals)

3. Select next subreddit for commenting:
   - Prioritize subreddits with no activity today or under limit
   - Prioritize subreddits with oldest last activity time

4. Check subreddit specifics in resources/subreddits.md:
   - Core community rules
   - Community nature
   - Good topics to answer
   → Reflect this information when selecting posts

Step 2: Access Reddit and Explore Posts

1. Access Reddit with Playwright MCP
   → browser_navigate("https://www.reddit.com/r/{selected_subreddit}/new/")
   or
   → browser_navigate("https://www.reddit.com/r/{selected_subreddit}/rising/")

2. Page snapshot
   → browser_snapshot()

3. Criteria for selecting posts to comment on:
   • Posts where you can share insights or provide feedback
   • ⚠️ CRITICAL: Posts you haven't commented on today
     - Check activity log in tracking/reddit/today's-date.md file
     - Extract list of post URLs from today's comments
     - Verify selected post URL is NOT in that list
     - Absolutely NO duplicate comments on same post
   • OK even if not related to your service/field
   • Relevance to "good topics to answer" from Step 1
   • Avoid posts with already hundreds of comments

4. Secure URL of selected post
   → Check and record post link in snapshot
   → Navigate directly to this URL in next Step

Step 3: Deep Analysis of Post Content and Existing Comments

⚠️ CRITICAL: Must perform this step before writing comment

0. Navigate directly to post
   → browser_navigate(post URL secured in Step 2)
   → Navigate directly to URL, don't click on post (prevents click errors)
   → browser_snapshot()

1. Read post content accurately:
   - Understand what OP is actually asking
   - Don't react only to keywords—understand full context
   - Distinguish between hypothetical questions and actual problem complaints

2. Understand OP's intent:
   - Seeking specific help? (problem solving)
   - Seeking opinions/discussion? (hypothetical scenario)
   - Information sharing? (experience story)

3. Analyze existing comments:
   - Check how others interpreted
   - Understand how community is receiving this post
   - Check tone and answering style

4. Decide comment direction:
   - Is this post worth answering?
   - From what angle should I answer?
   - Can I naturally answer in my style?

5. ⚠️ CRITICAL: Determine if site/link verification needed:
   - Did OP provide website/app link?
   - Are there expressions like "feedback requested", "honest feedback", "looking for feedback"?
   - Is feedback requested on UX, design, performance that requires actual verification?

   → If YES:
     • Visit actual site with browser_navigate(provided link)
     • Check UI/UX with browser_snapshot()
     • Write feedback based ONLY on what you actually saw
     • Absolutely NO speculative feedback on things you didn't see

   → If NO:
     • Can answer from post content alone
     • General advice or experience sharing

⚠️ Proceed to Step 4 only after clearly verifying analysis results

Step 4: Write Comment

1. Draft comment based on Step 3 analysis results:
   - Answer matching OP's actual question
   - Practically helpful content
   - Match subreddit tone
   - Focus on 1-2 points (don't try to explain everything)

Step 5: Personalization Review (Loop)

1. Check resources/personalization_reddit.md file
   → Sequentially check 16 personalization checklist items based on actual comment style
   → Especially important: #4 personal experience, #13 experience pattern, #15 question intent understanding, #16 site verification

2. Check style patterns:
   • Which pattern (1-8) is it closest to?
   • Does it capture that pattern's characteristics well?
   • Does it look like you wrote it?

3. Review process:
   • All items PASS → Proceed to Step 6
   • Any violation → Revise comment and re-review from Step 5 beginning

Detailed personalization guide: See resources/personalization_reddit.md

Step 6: Post Comment

1. Click comment input box
   → Check comment input element after browser_snapshot()
   → browser_click(comment box ref)

2. Input comment content
   → browser_type(reviewed comment)

3. Click post button
   → browser_click(post button ref)

4. Secure comment URL
   → Copy comment permalink after posting

Step 7: Judge Potential Customer (Optional)

⚠️ CRITICAL: Judge accurately by referring to Step 3 analysis again

→ Refer to "Lead Selection Criteria" in leads/reddit.md
→ Classify as lead only users with actual problems (not hypothetical questions)

When lead discovered, update leads/reddit.md:
  - Username, subreddit, post URL
  - Post summary, selection reason, relevance

Step 8: Update Tracking

Update tracking/reddit/[today's-date].md file:

1. Activity status table by subreddit:
   - Increment comment count for that subreddit by +1
   - Update last comment time

2. Add to activity log:
   ### [HH:MM] r/subreddit
   - **Post**: [Title](URL)
   - **Topic Summary**: One-line summary of post content
   - **Comment Link**: [Comment URL]
   - **Comment Content**:

Full comment written

3. When potential customer discovered:
- Update 'leads/reddit.md' when potential customer discovered

File Reference Rules (Token Savings)

File	Reference Timing
resources/subreddits.md	Step 1 (subreddit selection)
resources/personalization_reddit.md	Step 5 (review)
resources/product.md	Step 7 (potential customer judgment)
leads/reddit.md	Step 7 (lead criteria check)

→ Reference only at relevant Step, don't read in advance

Cautions

1. Login Required: Check Reddit account login status
2. Rate Limiting: Too fast activity risks account restrictions
3. Community Rules: Must follow each subreddit's rules
4. Spam Prevention: Absolutely NO copy-pasting same content
5. Review Required: Rewrite if any checklist item violated
6. ⚠️ Step 3 Required: NEVER write comment without analyzing post content. Judging only by keywords can cause serious errors
7. ⚠️ Minimize Playwright MCP tokens:
   • Don't pass entire context when calling Playwright MCP
   • Concisely summarize only essential information needed for each MCP call
   • E.g.: Only minimal instructions like "Navigate to [URL]", "Click comment box", "Type: [text]"
   • Prevent errors from excessive input tokens
8. ⚠️ Post Navigation: Use browser_navigate directly with URL instead of clicking post (prevents click errors)
