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
   • 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

• Login Required: Check Reddit account login status

• Rate Limiting: Too fast activity risks account restrictions

• Community Rules: Must follow each subreddit's rules

• Spam Prevention: Absolutely NO copy-pasting same content

• Review Required: Rewrite if any checklist item violated

• ⚠️ Step 3 Required: NEVER write comment without analyzing post content. Judging only by keywords can cause serious errors

• ⚠️ 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

• ⚠️ Post Navigation: Use browser_navigate directly with URL instead of clicking post (prevents click errors)
