How to Build a Reddit Bot with OpenClaw (Step by Step)

What the Reddit Skill Does

The reddit-openclaw skill, created by ajitesh-kuppa-sivakumar on GitHub, gives your OpenClaw agent read-only access to Reddit without requiring any API keys or OAuth credentials.

It works by appending .json to standard Reddit URLs, which returns structured JSON data from Reddit's public endpoints. This means your agent can:

• Read posts and comments from any public subreddit.
• Search for keywords across Reddit or within specific subreddits.
• Browse hot, new, top, and rising posts in any subreddit.
• Read full comment threads on specific posts.
• Monitor mentions of your brand, product, or competitors.

The skill does not support posting, commenting, voting, or any write operations. It is strictly read-only, which means it cannot violate Reddit's terms of service around bot posting and also requires no credential management on your end.

For general skill installation and management, see our OpenClaw skills complete guide.

Step 1: Install the Reddit Skill

Install via ClawHub

The fastest installation method uses ClawHub, OpenClaw's skill marketplace:

# Install the reddit-openclaw skill from ClawHub
openclaw skill install reddit-openclaw

Install from GitHub

Alternatively, install directly from the GitHub repository:

# Clone the skill into your OpenClaw skills directory
cd ~/.openclaw/skills/
git clone https://github.com/ajitesh-kuppa-sivakumar/reddit-openclaw.git

# Verify the skill is detected
openclaw skill list

Verify Installation

After installation, verify the skill is loaded and functional:

# Test the skill with a simple subreddit read
openclaw run "Read the top 5 posts from r/technology"

You should see the agent return the titles, scores, and comment counts from the top posts. If you get an error about the skill not being found, check that the skill directory is correctly placed in ~/.openclaw/skills/ and restart OpenClaw.

If tools are disabled after a recent update, see our tools disabled fix guide.

Step 2: Configure Keyword Monitoring

Create a Monitoring Configuration

Create a file at ~/.openclaw/skills/reddit-openclaw/config.json to define the keywords and subreddits you want to monitor:

{
  "monitors": [
    {
      "name": "competitor_tracking",
      "subreddits": ["entrepreneur", "startups", "SaaS", "smallbusiness"],
      "keywords": ["your-competitor-name", "your-product-name", "your-industry-term"],
      "sort": "new",
      "limit": 25
    },
    {
      "name": "market_research",
      "subreddits": ["artificial", "MachineLearning", "ChatGPT", "LocalLLaMA"],
      "keywords": ["ai agent", "autonomous agent", "openclaw"],
      "sort": "hot",
      "limit": 15
    },
    {
      "name": "reputation",
      "subreddits": ["all"],
      "keywords": ["your-brand-name", "your-product-name"],
      "sort": "new",
      "limit": 50
    }
  ]
}

Add Monitoring Instructions to SOUL.md

Add a section to your agent's SOUL.md that tells it how to process Reddit monitoring results:

## Reddit Monitoring

When running Reddit keyword monitoring:
1. Check each configured subreddit for posts matching the keywords
2. Filter out posts older than 24 hours
3. Rank results by relevance (keyword in title > keyword in body > keyword in comments)
4. Summarize each relevant post: title, subreddit, score, key discussion points
5. Flag any posts that mention [your brand] with sentiment analysis
6. Deliver results as a formatted digest to Telegram

Step 3: Set Up the Daily Digest

Create a Cron Job

Schedule a daily Reddit digest that runs every morning before you start work:

# Edit your crontab
crontab -e

# Add daily Reddit digest at 7:30 AM
30 7 * * * cd ~/.openclaw && openclaw run "Run the daily Reddit monitoring digest. Check all configured subreddits and keywords. Send the formatted digest to Telegram."

Digest Format

Configure your agent to deliver digests in a structured format. Add this to your SOUL.md:

## Daily Reddit Digest Format

When delivering the Reddit digest, use this format:

**Reddit Digest — [Date]**

**Competitor Mentions (X posts)**
- [Post title] — r/[subreddit] — [score] points — [key takeaway]

**Market Trends (X posts)**
- [Post title] — r/[subreddit] — [score] points — [key takeaway]

**Brand Mentions (X posts)**
- [Post title] — r/[subreddit] — [sentiment: positive/negative/neutral] — [key takeaway]

**Action Items**
- [Any posts that need a response or attention]

Cost Estimate

A daily Reddit digest that checks 10 subreddits for 5 keywords and summarizes the results costs approximately $0.02-0.05 per run in LLM API tokens (using Claude Sonnet). That is roughly $0.60-1.50 per month for a daily digest — significantly cheaper than any commercial Reddit monitoring tool.

Step 4: Browse Subreddits Programmatically

Ad-Hoc Subreddit Browsing

Beyond scheduled monitoring, you can ask your agent to browse Reddit on demand through any connected messaging channel:

# Via Telegram or any connected channel:
"What are the top posts on r/startups this week about AI tools?"

"Summarize the discussion in r/SaaS about pricing strategies from the last 3 days."

"Find Reddit threads where people complain about [competitor product]."

"What questions are people asking about AI agents in r/entrepreneur?"

Deep Thread Analysis

The skill can read full comment threads, which is valuable for understanding nuanced discussions:

# Ask your agent to analyze a specific thread
"Read this Reddit thread and summarize the main arguments:
https://reddit.com/r/startups/comments/[post-id]/[title]/"

# Or find and analyze threads on a topic
"Find the most discussed thread about AI pricing in r/SaaS this month
and summarize the top 20 comments."

Competitor Intelligence

Use subreddit browsing for structured competitor analysis:

# Competitor research prompt
"Search r/SaaS, r/startups, and r/entrepreneur for posts mentioning
[Competitor A] or [Competitor B] from the last 7 days. For each post:
1. What problem is the user describing?
2. What is their sentiment toward the competitor?
3. Is there an opportunity for our product?
Compile the results into a competitive intelligence brief."

Practical Use Cases

1. Competitor Monitoring

Track what users say about competitors across relevant subreddits. Set up keyword monitors for competitor brand names, product names, and common misspellings. The daily digest flags negative sentiment threads where users are actively looking for alternatives — prime opportunities for awareness.

2. Market Research

Reddit is one of the most honest sources of user feedback. Monitor subreddits where your target audience discusses problems your product solves. Track feature requests, pricing complaints, and workflow pain points. Feed this data into your product roadmap or content strategy.

3. Content Idea Generation

Questions asked on Reddit are search queries people type into Google. Monitor r/[your-industry] for frequently asked questions, then create content that answers them. Your agent can compile a weekly "content ideas from Reddit" digest that feeds directly into your content calendar.

4. Reputation Tracking

Monitor mentions of your brand, product, founder name, and common misspellings across all of Reddit. Get immediate alerts for negative sentiment threads that could escalate. This is particularly valuable for early-stage startups where a single negative Reddit thread can impact perception.

5. Hiring Intelligence

Monitor job-related subreddits (r/cscareerquestions, r/remotework, r/forhire) for candidates discussing the skills and roles you are hiring for. Understand salary expectations, workplace preferences, and candidate sentiment in your industry.

Advanced Configuration

Rate Limiting

Reddit's public JSON endpoints allow approximately 30 requests per minute from a single IP address. The reddit-openclaw skill includes built-in rate limiting, but if you are monitoring many subreddits, space your requests to avoid temporary blocks:

# In config.json, add a delay between requests
{
  "rateLimiting": {
    "requestsPerMinute": 20,
    "delayBetweenRequests": 3000
  }
}

Filtering and Quality Control

Add filters to reduce noise in your monitoring results:

{
  "filters": {
    "minScore": 5,
    "minComments": 3,
    "excludeFlairs": ["Meme", "Shitpost"],
    "maxAge": "24h"
  }
}

Integration with Other Skills

Combine the Reddit skill with other OpenClaw capabilities for more powerful workflows:

• Email integration: Send weekly Reddit intelligence reports to your team via email.
• CRM integration: When Reddit mentions indicate a potential lead, create a CRM entry automatically.
• Content pipeline: Feed Reddit questions into your content creation workflow with the content pipeline automation skill.
• Notion/Obsidian: Save relevant Reddit threads to your knowledge base for reference.

Frequently Asked Questions

Does the OpenClaw Reddit skill require API keys?

No. The reddit-openclaw skill by ajitesh-kuppa-sivakumar uses Reddit's public JSON endpoints (appending .json to any Reddit URL) which do not require authentication. This means read-only access to posts, comments, and subreddit listings without registering a Reddit API application or managing OAuth tokens. Rate limits apply — approximately 30 requests per minute from a single IP.

Can OpenClaw post or comment on Reddit?

Not with the read-only reddit-openclaw skill. This skill only supports reading posts, comments, and subreddit listings. To post or comment on Reddit, you would need to build a custom skill using Reddit's authenticated API with OAuth credentials. Most operators use the read-only skill for monitoring and research, then manually engage based on the agent's analysis.

How often should I run Reddit keyword monitoring?

A daily cron job (once every 24 hours) works well for most monitoring use cases like competitor tracking and market research. For time-sensitive monitoring (product launches, PR crises), run every 4-6 hours. Running more frequently than hourly risks rate limiting from Reddit's public endpoints and wastes API tokens on unchanged data. The daily digest format is the most cost-effective approach at approximately $0.02-0.05 per digest in LLM API costs.
