How I Automated My App's Entire Blog Pipeline

I built a system that researches, writes, validates, and publishes blog posts about my app — then tweets about them — all without me touching a keyboard.

Here’s the full breakdown ↓

The Problem: Blogging Is a Full-Time Job Nobody Has Time For

When you’re an indie developer, you wear every hat. Code. Design. Support. Marketing. And somewhere at the bottom of the to-do list: “write blog posts for SEO.”

I knew content marketing mattered. Arc — my AI screen assistant for Android — needed blog posts to rank, to get found, to explain what it does in a way the Play Store description can’t.

But writing a blog post took me 3-4 hours. Research. Drafting. Editing. Finding screenshots. SEO optimization. Formatting. Publishing. Then tweeting about it.

That’s a full afternoon I should’ve spent building.

The Result: 28+ Blog Posts, Zero Manual Writing

Today, the Rethink Hub blog has 28+ published posts. Every one of them was researched, written, validated, and published by an automated pipeline I built with OpenClaw.

The pipeline:

Picks topics based on real search trends
Pulls live usage data from Google Analytics (real numbers, not made up)
Writes SEO-optimized posts with proper keywords, internal links, and FAQs
Validates every image path and SEO rule before publishing
Pushes to the website and announces on X — with the hero image attached

My role? I approve the topic direction. Everything else runs on its own.

How It Works: 6 Phases, 3 Specialized Agents

The pipeline has six phases. Three of them are handled by specialized AI agents, each with their own expertise and instructions.

Phase 1: Research

The pipeline starts by searching for trending topics — Android problems people are actually searching for. It checks what I’ve already covered, finds keyword gaps, and picks one topic that maps to an Arc feature.

Then it pulls real data. Google Analytics API gives me actual usage numbers: how many AI summaries were generated this month, how many custom actions ran, which countries my users are in. These numbers become the backbone of every post — they’re information nobody else can write about because they’re my data.

Phase 2: Arc Expert Agent

This is where it gets interesting. OpenClaw spawns a dedicated “Arc Expert” agent that has its own knowledge base — a folder of feature documentation, real screenshot filenames, use cases, and capabilities for every Arc feature.

The Arc Expert doesn’t guess. It reads from a curated knowledge base of real screenshots, real feature descriptions, and real use cases. It returns:

What the feature does (in 2-3 sentences)
Key capabilities (bullet points)
3-4 real-world use cases
Exact screenshot filenames from a validated inventory (no hallucinated images)
The Play Store link
Accessibility-specific benefits

This is the piece that makes my blog posts actually accurate. The Arc Expert knows which screenshots exist, what they show, and how to match them to the topic. Before this, I had agents inventing image paths that didn’t exist — broken images on the live site.

Phase 3: Writing Expert Agent

Next, OpenClaw spawns a “Writing Expert” — an agent trained specifically for Rethink blog standards. Its instructions include:

SEO guidelines (title ≤ 60 chars, description 150-160 chars, keyword placement rules)
Voice: first-person, “I/my” (not “we/our”) — because I’m an indie dev, not a corporation
Structure: hook → problem → solution → data → FAQ → CTA
Mandatory information gain: every post must include real Arc usage stats from Phase 1
Image path rules: only /images/arc/how-to/ prefix, only real filenames from the Arc Expert’s output

The Writing Expert reads the research file, the Arc Expert’s output, and its own style guide, then writes a complete MDX blog post — frontmatter, body, FAQ, CTA, everything.

Phase 4: Image Validation

Before publishing, a validation script scans the generated MDX for broken image paths. It checks:

No paths pointing to directories that don’t exist
No hallucinated filenames (only real screenshots from the inventory)
All image references resolve to actual files on disk

If anything fails, the pipeline stops. I get notified. No broken images go live.

This step exists because I learned the hard way — early versions of the pipeline published posts with broken images. The AI was making up filenames that sounded plausible but didn’t exist. Now I validate before every publish.

Phase 5: SEO Audit

Another automated check. A script validates:

Title length and keyword placement
Meta description length and structure
Internal link count (minimum 2)
External link presence
FAQ section existence
Author field and voice consistency
Play Store CTA

Again — if anything fails, the pipeline stops. No SEO-challenged posts go live.

Phase 6: Publish + Announce

The final agent — the “Publisher” — does two things:

Blog: Sets the post to published, commits, and pushes to the website repo. The site rebuilds automatically.
X Announcement: Writes a tweet about the new post with a hook, topic summary, link, and hashtags. Then publishes it via the X API — with the blog’s hero image attached.

That’s it. From topic research to live blog post to X announcement, the whole cycle runs on a daily cron. If the pipeline is idle, it starts a new cycle. If it’s mid-cycle, it picks up where it left off.

The Knowledge Base: Why Accuracy Matters

The secret sauce isn’t just automation — it’s the knowledge base.

The Arc Expert has a dedicated folder of feature documentation. When the writing agent needs to talk about Arc’s Info Vault, it doesn’t hallucinate capabilities. It reads from curated docs that describe exactly what Info Vault does, how to use it, and which screenshots demonstrate it.

This solves the #1 problem with AI-generated content: it’s generic and often wrong. My posts include real numbers (“Over 3,300 AI summaries generated per month”), real features (with screenshots that actually exist), and real use cases that come from the product itself — not the AI’s imagination.

What I Still Do Manually

The pipeline handles 90% of the work. Here’s what I still touch:

Topic direction: I approve the general focus area (or let it pick based on trends)
Spot checks: I’ll glance at the published post to make sure nothing weird slipped through
Strategic decisions: Which features to highlight, which audience to target next

Everything else — research, writing, validation, publishing, announcement — is automated.

The Stack

For anyone wanting to build something similar:

OpenClaw: Orchestrates the pipeline, manages state, spawns agents
Durable Pipeline Skill: Defines the 6-phase flow with state tracking, failure recovery, and resume-from-last-step
3 Specialized Agents: Arc Expert, Writing Expert, Publisher — each with their own persona, instructions, and constraints
Google Analytics API: Pulls real usage data for information gain
Validation Scripts: Image path checker and SEO auditor that gate the pipeline
Git + Static Site: Push to repo → site rebuilds → live
X API v2: Automated tweet publishing with image attachment

What I Learned Building This

Validation layers are non-negotiable. Without the image checker and SEO auditor, AI agents will publish broken content. They don’t know what they don’t know.
Specialized agents beat general-purpose ones. The Arc Expert only knows Arc features. The Writing Expert only writes blog posts. The Publisher only publishes. Each is small, focused, and reliable.
Knowledge bases > prompting. Instead of telling an agent “make sure you use real screenshots,” give it a curated list of real filenames. Instead of “include accurate stats,” give it the actual data. Constraints beat instructions.
State machines prevent duplicate work. The pipeline tracks what’s been completed, what’s in progress, and what’s failed. If it crashes mid-cycle, it picks up from the last successful step — not from the beginning.
Real data is your moat. Anyone can ask an AI to “write a blog post about AI apps.” Nobody else can write “Arc users generate 3,300+ AI summaries per month” because that’s my data. Information gain is the ranking signal that matters in 2026.

Want to See It in Action?

Every blog post on appsrethink.com was produced by this pipeline. Read a few — you’ll notice they’re not generic AI slop. They’re specific, data-backed, and technically accurate because the system was built to enforce that.

FAQ

Can I build something like this without OpenClaw?

You could wire together scripts and cron jobs, but you’d lose the agent orchestration, state management, and failure recovery. The specialized agent pattern — where each AI agent has its own knowledge base and instructions — is what makes the output reliable. Without that, you get generic content and broken images.

How do you prevent AI from making stuff up?

Two ways. First, the Arc Expert only works from a curated knowledge base — it can’t invent features or screenshots that don’t exist. Second, validation scripts catch anything that slips through. If an image path doesn’t point to a real file on disk, the pipeline stops. No exceptions.

Does this actually rank on Google?

Yes. The SEO audit step enforces title length, keyword placement, internal links, and structured data before anything goes live. Combined with real usage data that no other site can provide (information gain), the posts rank for their target keywords. The “information gain” signal — content that provides data unavailable elsewhere — is increasingly important for Google in 2026.

What happens when the pipeline fails?

It stops and notifies me. The state machine tracks progress through each phase, so if something breaks at Phase 3, it doesn’t retry Phase 1 and 2. It picks up from the failure point. This is critical — without it, a crashed pipeline would either duplicate work or lose progress entirely.

How long does one blog post take end-to-end?

About 15-20 minutes of wall time across all six phases. Most of that is the writing agent working. The validation and publishing phases run in seconds. Compare that to 3-4 hours of manual work per post.

This blog post was written by me (Mamata), but the system that writes all the OTHER blog posts? That’s OpenClaw.
