How to Set Up and Use Auto Commenter
Auto Commenter is a Claude skill (MCP-powered automation) that uses browser automation via Playwright to post personalized, authentic-sounding comments in online communities on your behalf. It replicates your personal writing style based on a sample of your previous comments and follows a 16-point quality checklist to ensure comments fit each community's norms and tone. Marketers, founders, and community builders use it to maintain a consistent presence on Reddit and other platforms while spending minimal manual effort — it supports lead identification, daily activity logging, and batch quota execution.

- Claude Desktop with MCP support enabled
- Playwright MCP server installed and configured in Claude Desktop
- A Reddit account (or accounts on other target platforms)
- 8-10 sample comments in your own voice to build a personalization profile

npm install -g @playwright/mcpCreate your personalization profile
Collect 8-10 of your own Reddit comments (or comments from the target platform). Paste them into Claude and ask it to generate a personalization guide describing your writing style, tone, and patterns. Save the output to the path below.
# Save LLM-generated personalization output to:
.claude/skills/reddit-commenter/resources/personalization_reddit.mdDefine your target communities
Research the rules and tone of the subreddits or communities you want to engage with. Create a file listing each community with its rules and recommended engagement style.
# Create and populate:
.claude/skills/reddit-commenter/resources/subreddits.mdAdd product information (optional)
If you want the commenter to occasionally mention a product or service, add details to the product file. Keep descriptions natural and relevant to each community's interests.
# Optional — add product context to:
.claude/skills/reddit-commenter/resources/product.mdConfigure Claude Desktop and launch
Add both Playwright MCP and Auto Commenter to your Claude Desktop config, then ask Claude to begin posting comments.

Commands to trigger Auto Commenter's single, batch, and review modes.
- "Write one comment on r/ClaudeAI about a recent post"
- "Fill today's quota across my target subreddits"
- "Show today's Reddit activity and metrics"
- "Find posts in r/SideProject where I could add value and draft comments"
- "Review the last 5 comments posted and flag any that don't match my style guide"Troubleshooting Auto Commenter
Playwright browser fails to launch or pages don't load
Run 'npx playwright install' to download the browser binaries required by Playwright. On Linux you may also need to install system dependencies: npx playwright install-deps.
Comments sound generic and don't match my writing style
Improve the personalization_reddit.md file by providing more diverse sample comments that show your range of vocabulary, sentence length, and humor. The more examples you include, the more accurately the style will be replicated.
Reddit blocks or flags the automated account
Use natural pacing — don't fill hundreds of quotas at once. The tool is designed for modest daily engagement. Respect each subreddit's rules in subreddits.md and avoid any community that prohibits self-promotion or bot activity.
