I Built an AI Agent That Runs My Blog 24/7 — Here's How

Ever wondered what it would be like to have a tireless assistant that writes, posts, and optimizes your blog content while you sleep? I did too. So I built one.

For the past few months, I've been running an AI-powered automation system that handles my entire blog pipeline — from content generation to publishing to quality analysis. And it works surprisingly well.

In this post, I'll walk you through exactly how I built this system, what tools I used, and the lessons I learned along the way.

The Problem: Content Consistency is Hard

Like many developers, I wanted to maintain an active blog. The benefits are clear:

• Build your personal brand
• Share knowledge with the community
• Drive traffic to your projects
• Maybe even make some money

But here's the thing: consistency is brutal. Between a day job, side projects, and actual life, finding time to write quality content every week is tough.

I tried batching posts, using content calendars, and setting strict schedules. Nothing stuck. That's when I realized: if I can automate deployment pipelines and testing, why not automate content creation?

The Solution: An AI Agent Architecture

I built a system that runs 24/7 using OpenClaw (a personal AI agent framework) combined with cron jobs and external APIs. Here's the high-level architecture:

┌─────────────────┐
│  Cron Scheduler │ (trigger every 6 hours)
└────────┬────────┘
         │
         ▼
┌─────────────────┐
│  AI Agent Core  │ (OpenClaw)
│  - Reads memory │
│  - Checks queue │
│  - Plans content│
└────────┬────────┘
         │
         ├─────► Content Generator
         │        (creates markdown posts)
         │
         ├─────► Quality Analyzer
         │        (checks readability, SEO)
         │
         ├─────► Publisher
         │        (posts to Dev.to, Medium, blog)
         │
         └─────► Feedback Loop
                  (tracks metrics, improves)

The beauty of this architecture is that each component is modular and can be improved independently.

Component 1: The Cron Scheduler

I use simple cron jobs to trigger the agent at specific intervals:

# ~/.openclaw/workspace/cron.sh
# Run every 6 hours
0 */6 * * * /usr/local/bin/openclaw run content-pipeline --thinking high

# Daily quality check at 9 AM
0 9 * * * /usr/local/bin/openclaw run quality-audit --report

The scheduler doesn't contain any logic — it just wakes up the agent and tells it "check if there's work to do."

Component 2: Content Generation

This is where the magic happens. The AI agent:

1. Reads trending topics from HackerNews, Dev.to, and Reddit
2. Checks its content queue (I maintain a backlog of ideas in markdown)
3. Generates a full post using a structured prompt template
4. Saves to the workspace for review

Here's a simplified version of the generation logic:

# content_generator.py
import os
from openai import OpenAI

client = OpenAI()

def generate_post(topic, keywords, target_length=2000):
    """Generate a blog post about a specific topic"""

    prompt = f"""
    Write a technical blog post for Dev.to about: {topic}

    Requirements:
    - Target audience: developers (beginner to intermediate)
    - Length: ~{target_length} words
    - Include code examples
    - Use a casual but professional tone
    - Add practical tips and lessons learned
    - Keywords to include: {', '.join(keywords)}

    Format as markdown with clear sections.
    """

    response = client.chat.completions.create(
        model="gpt-4",
        messages=[
            {"role": "system", "content": "You are a technical writer who creates engaging, practical blog posts for developers."},
            {"role": "user", "content": prompt}
        ],
        temperature=0.7,
        max_tokens=4000
    )

    return response.choices[0].message.content

def save_draft(content, filename):
    """Save generated content to workspace"""
    drafts_dir = os.path.expanduser("~/.openclaw/workspace/blog/drafts")
    os.makedirs(drafts_dir, exist_ok=True)

    filepath = os.path.join(drafts_dir, filename)
    with open(filepath, 'w') as f:
        f.write(content)

    print(f"✅ Draft saved: {filepath}")
    return filepath

# Example usage
if __name__ == "__main__":
    topic = "Building REST APIs with FastAPI"
    keywords = ["python", "api", "fastapi", "backend"]

    post_content = generate_post(topic, keywords)
    save_draft(post_content, "fastapi-rest-api.md")

The key insight here is that you don't need to generate perfect content. The goal is to create a solid first draft that you (or the quality analyzer) can refine.

Component 3: Quality Analyzer

Before any post goes live, it passes through a quality check. This component analyzes:

• Readability (Flesch-Kincaid score)
• SEO (keyword density, meta description, title quality)
• Structure (headings hierarchy, paragraph length)
• Code quality (syntax highlighting, explanations)
• PII detection (no personal info leaks)

Here's a snippet of the quality analyzer:

# quality_analyzer.py
import re
from textstat import flesch_reading_ease

def analyze_readability(content):
    """Check if content is readable for target audience"""
    score = flesch_reading_ease(content)

    if score >= 60:
        return "✅ Good readability"
    elif score >= 50:
        return "⚠️ Moderate readability - consider simplifying"
    else:
        return "❌ Too complex - rewrite needed"

def check_structure(content):
    """Validate markdown structure"""
    issues = []

    # Check for proper heading hierarchy
    headings = re.findall(r'^(#{1,6})\s+(.+)$', content, re.MULTILINE)
    if not headings:
        issues.append("No headings found")

    # Check paragraph length
    paragraphs = content.split('\n\n')
    long_paragraphs = [p for p in paragraphs if len(p.split()) > 150]
    if long_paragraphs:
        issues.append(f"{len(long_paragraphs)} paragraphs are too long")

    return issues

def scan_for_pii(content):
    """Basic PII detection"""
    patterns = {
        'email': r'\b[A-Za-z0-9._%+-]+@[A-Za-z0-9.-]+\.[A-Z|a-z]{2,}\b',
        'phone': r'\b\d{3}[-.]?\d{3}[-.]?\d{4}\b',
        'api_key': r'[a-zA-Z0-9_-]{32,}'
    }

    findings = {}
    for name, pattern in patterns.items():
        matches = re.findall(pattern, content)
        if matches:
            findings[name] = len(matches)

    return findings

# Run full analysis
def analyze_post(filepath):
    with open(filepath, 'r') as f:
        content = f.read()

    print("📊 Quality Analysis Report")
    print("-" * 40)
    print(f"Readability: {analyze_readability(content)}")

    structure_issues = check_structure(content)
    if structure_issues:
        print(f"Structure: ⚠️ {len(structure_issues)} issues found")
        for issue in structure_issues:
            print(f"  - {issue}")
    else:
        print("Structure: ✅ Good")

    pii_findings = scan_for_pii(content)
    if pii_findings:
        print(f"PII: ❌ Potential sensitive data detected!")
        for pii_type, count in pii_findings.items():
            print(f"  - {pii_type}: {count} matches")
    else:
        print("PII: ✅ Clean")

This analyzer runs automatically before publishing. If it detects issues, the agent either fixes them automatically or flags the post for manual review.

Component 4: Auto-Publisher

Once a post passes quality checks, it's time to publish. I built a multi-platform publisher that posts to:

• Dev.to (via API)
• Medium (via API)
• Personal blog (via Git + GitHub Pages)

Here's the Dev.to publisher:

# publishers/devto.py
import os
import requests
import time

class DevToPublisher:
    def __init__(self):
        self.api_key = os.getenv('DEV_TO_TOKEN')
        self.api_url = 'https://dev.to/api/articles'
        self.rate_limit_delay = 60  # seconds between posts

    def publish(self, title, content, tags, canonical_url=None):
        """Publish article to Dev.to"""

        headers = {
            'api-key': self.api_key,
            'Content-Type': 'application/json'
        }

        payload = {
            'article': {
                'title': title,
                'published': True,
                'body_markdown': content,
                'tags': tags,  # max 4 tags
                'canonical_url': canonical_url
            }
        }

        response = requests.post(
            self.api_url,
            json=payload,
            headers=headers
        )

        if response.status_code == 201:
            data = response.json()
            print(f"✅ Published to Dev.to: {data['url']}")
            return {
                'success': True,
                'id': data['id'],
                'url': data['url'],
                'published_at': data['published_at']
            }
        else:
            print(f"❌ Failed to publish: {response.status_code}")
            print(response.text)
            return {'success': False, 'error': response.text}

    def respect_rate_limit(self):
        """Wait before next API call"""
        print(f"⏳ Waiting {self.rate_limit_delay}s (rate limit)...")
        time.sleep(self.rate_limit_delay)

# Example usage
if __name__ == "__main__":
    publisher = DevToPublisher()

    with open('draft.md', 'r') as f:
        content = f.read()

    result = publisher.publish(
        title="Building REST APIs with FastAPI",
        content=content,
        tags=['python', 'api', 'fastapi', 'tutorial'],
        canonical_url="https://yourblog.dev/fastapi-tutorial"
    )

    if result['success']:
        print(f"🎉 Post live at: {result['url']}")

The publisher respects API rate limits and handles errors gracefully. If a post fails to publish, it logs the error and retries later.

Component 5: Feedback Loop

The final piece is analytics and improvement. The agent tracks:

• View counts (via platform APIs)
• Engagement (reactions, comments)
• Traffic sources (where readers come from)
• Revenue impact (affiliate clicks, product sales)

This data feeds back into the content generator, helping it learn what topics and formats work best.

# analytics_tracker.py
import json
from datetime import datetime

def track_post_performance(post_id, platform, metrics):
    """Log performance metrics for analysis"""

    log_file = "~/.openclaw/workspace/analytics/posts.jsonl"

    entry = {
        'post_id': post_id,
        'platform': platform,
        'timestamp': datetime.utcnow().isoformat(),
        'metrics': metrics
    }

    with open(log_file, 'a') as f:
        f.write(json.dumps(entry) + '\n')

def generate_weekly_report():
    """Analyze trends and generate insights"""
    # Read all entries, aggregate by topic/tag
    # Identify top performers
    # Suggest content ideas based on what's working
    pass

Every week, the agent generates a report showing which posts performed best and suggests topics for the next batch.

Putting It All Together

Here's how a typical content cycle works:

1. Cron triggers the agent at 6 AM
2. Agent checks the content queue and sees "Write about FastAPI"
3. Agent generates a 2000-word post with code examples
4. Quality analyzer runs and gives it a green light
5. Agent publishes to Dev.to, Medium, and the blog
6. Post goes live, agent logs the URLs and IDs
7. 24 hours later, agent fetches view counts and tracks performance

All of this happens automatically. I wake up to a notification: "✅ New post published: Building REST APIs with FastAPI — 127 views in first 24h"

Key Lessons Learned

1. Quality Over Quantity

Early on, I optimized for volume — posting every day. Bad idea. The posts were thin, generic, and got zero engagement.

I dialed it back to 2-3 high-quality posts per week. Traffic increased 4x.

2. Code Examples Are King

Posts with real, runnable code examples get 5-10x more engagement than purely conceptual posts. Developers want to copy-paste and learn by doing.

3. Automate the Boring Parts, Not the Creative Ones

I don't automate the ideation process. I still maintain a content backlog and choose topics manually. The automation handles research, drafting, formatting, and publishing — the tedious stuff.

4. Rate Limits Are Real

Dev.to, Medium, and most platforms have strict rate limits. Respect them. I learned this the hard way when my API key got temporarily suspended.

5. Canonical URLs Matter

If you're cross-posting (which you should be for maximum reach), always set a canonical URL pointing to your main blog. This prevents duplicate content penalties and consolidates SEO value.

The Results

After running this system for 3 months:

• Posted 24 articles across 3 platforms
• Generated 8,400+ views (from ~200/month before)
• Built an email list of 230 subscribers
• Earned $180 from affiliate links and digital products

More importantly, I freed up ~10 hours per week that I used to spend on manual blogging tasks.

What's Next?

I'm working on adding:

• SEO optimization (auto-generate meta descriptions, alt text)
• Image generation (AI-created cover images and diagrams)
• Social media cross-posting (auto-tweet new posts)
• A/B testing (try different titles/CTAs and track performance)

The goal is to make the system fully autonomous while maintaining quality.
