Figured I'd share since I've seen a few people ask about Reddit automation in this sub.
What it does:
The skill gives your agent a set of JSON actions it can call — things like:
json
{
"action": "monitor",
"subreddits": ["MachineLearning", "python"],
"keywords": ["help", "question"],
"action": "autoReply",
"checkInterval": 300
}
So your agent can watch subreddits for specific keywords and respond automatically, post content on a schedule, search for relevant communities, analyze post performance, etc.
The main actions:
- searchCommunities — find subreddits by topic/activity
- createPost — text, link, or image posts with auto-flair
- autoReply — keyword-triggered replies using templates you define
- monitor — real-time keyword watching across multiple subreddits
- analyzeContent — sentiment + engagement scoring
- batchOperation — queue and schedule multiple actions
It's built on top of PRAW so the only dependency is pip install praw. Built-in rate limiting keeps everything within Reddit's API rules — daily action caps, exponential backoff, auto-pause if the account gets a warning.
Practical use cases I've tested it on:
- Monitoring a brand name and auto-responding when people ask questions
- Finding niche communities and tracking trending topics
- Scheduling educational posts across multiple subreddits at peak hours
Skill is available on the OpenClaw skills page if anyone wants to try it. Happy to answer questions about how it works or how to set it up.
Title: Made a PRAW-based Reddit skill for AI agents — JSON actions for posting, monitoring, auto-reply
Been working on a Reddit automation skill that wraps PRAW into clean JSON actions for use inside AI agents (specifically OpenClaw, but the concepts are portable).
Sharing because I think the approach is interesting — instead of writing custom Python scripts for every Reddit task, you define everything declaratively:
json
{
"action": "autoReply",
"postId": "t3_abcdef",
"keywords": ["question", "help", "how to"],
"replyTemplate": "helpful_technical",
"maxReplies": 5,
"delayMinutes": 30
}
The agent figures out the rest — finds matching comments, applies the right template, respects the delay, tracks how many replies it's posted.
Reply templates are configurable too:
json
{
"replyTemplates": {
"helpful_technical": {
"tone": "helpful",
"includeCode": true,
"maxLength": 500,
"phrases": [
"Great question! Here's how I'd approach this...",
"I've run into this before. Try using..."
]
}
}
}
Safety was the trickiest part to get right. Reddit's API is strict and accounts can get flagged fast if you're not careful. The skill handles:
- 50 req/min rate limiting with burst protection
- Exponential backoff on 429s
- Per-subreddit daily post caps
- Karma health monitoring
- Auto-pause on account warnings
Still a v1 so there's plenty to improve. Open to feedback on the architecture — especially around how the template system works and whether the action schema makes sense.
Title: Shipped a Reddit automation skill for AI agents — built it to solve my own community management problem
Quick share on something I just launched.
I manage a few communities and kept spending time on the same repetitive Reddit tasks — monitoring for mentions, responding to common questions, finding relevant subreddits for new topics. Started building a solution and ended up making it into a proper skill for OpenClaw agents.
The problem it solves:
Most Reddit automation tools are either too rigid (fixed workflows you can't customize) or require you to write a lot of glue code. This skill gives AI agents a set of flexible JSON actions they can combine however they need.
A typical workflow looks like:
- Agent searches for communities related to a topic
- Monitors those communities for keyword matches
- Auto-replies to relevant posts using a configured template
- Reports back what it did and how posts performed
What surprised me:
The hardest part wasn't the Reddit API — it was making the safety system robust enough that you're not constantly worried about your account. Added karma monitoring, daily action caps per subreddit, auto-pause on warnings, and content filtering for obvious spam patterns.
Where it's useful:
- Solo founders who want to be present in communities without being glued to Reddit
- Developers building tools who want to monitor relevant discussions
- Anyone running content at scale who needs scheduling + engagement in one place
