Drafts, reviews, posts, and tracks Reddit comments for chosen subreddits end to end, using Playwright MCP to read and interact with the live page.

  • Works in 8 steps: Check Activity Status and Select Subreddit → Access Reddit and Explore Posts → Deep Analysis of Post Content and… → …
  • Drafting a comment for a specific Reddit post
  • SKILL.md covers Required Tool: Playwright MCP, Execution Workflow, File Reference Rules (Token… and Cautions
  • Reaches reddit.com

What it does

This skill uses only navigate, snapshot, click, type, and wait-for actions from Playwright MCP, navigating straight to URLs rather than clicking through the UI and reading the accessibility-tree snapshot instead of screenshots, both to save tokens and avoid stray clicks.

Each run checks a daily tracking file to select a subreddit, analyzes a post and its existing comments before drafting anything, then runs the draft through a personalization checklist of sixteen items, with particular weight on personal experience, matching the post's actual question, and verifying site-specific details, before posting and recording the result in the tracking file.

When your agent uses it

  • Drafting a comment for a specific Reddit post
  • Reviewing a drafted comment against a personalization checklist before posting
  • Tracking which subreddits and posts have already been commented on

Example prompts

  • “Draft a comment for this Reddit thread about home coffee grinders.”
  • “Run my draft comment through the personalization checklist before I post it.”
  • “Check today's tracking file for which subreddits are still pending.”

Requirements

  • Playwright MCP

Workflow steps

8 steps, taken from the step headings in SKILL.md.

  1. Check Activity Status and Select Subreddit
  2. Access Reddit and Explore Posts
  3. Deep Analysis of Post Content and Existing Comments
  4. Write Comment
  5. Personalization Review (Loop)
  6. Post Comment
  7. Judge Potential Customer (Optional)
  8. Update Tracking

What it can do on your machine

Read from SKILL.md and the folder at commit e7fdda1. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    No scripts in the folder and no shell commands in SKILL.md.

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    Hosts in commands or code, which the agent is likely to contact:

    • reddit.com

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Reddit Comment Automation loads about 2.1k tokens when it runs. Until then it costs about 49 tokens; SKILL.md has 351 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~49
When it runs · the whole SKILL.md, loaded when a task matches
~2.1k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

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 ToolPurpose
browser_navigateNavigate to Reddit pages
browser_snapshotCapture page structure (accessibility tree)
browser_clickClick elements (comment box, buttons, etc.)
browser_typeInput text (comment content)
browser_wait_forWait 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

Show full SKILL.md (157 more words)Show less

File Reference Rules (Token Savings)

FileReference Timing
resources/subreddits.mdStep 1 (subreddit selection)
resources/personalization_reddit.mdStep 5 (review)
resources/product.mdStep 7 (potential customer judgment)
leads/reddit.mdStep 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)
