Perfect 🚀 For dev.to, the tone can be a little more builder-oriented, hands-on, hacker-style compared to Medium (which leans more narrative). I’ll shuffle the order, add different examples, and keep it more concise but still engaging. Here’s a ready-to-publish draft:

How I Built a Semantic Firewall for AI — And Reached 600 Stars in 60 Days

Two months ago, I was just one person in Taiwan, building in silence.
Today, my project WFGY — a reasoning layer for AI — has crossed 600 GitHub stars in 60 days. No ads. No team. Just math and persistence.

Here’s what I learned, and why I think AI reasoning is the next big frontier.

The Pain Point Nobody Talks About

Everyone’s hyped about RAG (Retrieval-Augmented Generation). But here’s the dirty secret:

Your database might say:

A. The company went bankrupt in 2023.
B. The founder launched a product in 2022.

And your AI happily tells you:
➡️ “The company launched a revolutionary product in 2023.”

No error logs. No red flags. Just semantic drift — facts fused into a hallucination.

I call these the 16 hidden failure modes of AI reasoning. Some of the nastiest include:

No 1. Hallucination & chunk drift
No 5. Semantic ≠ embedding mismatch
No 6. Logic collapse & failed recovery
No 8. Debugging is a black box

This is why so many engineers are tweeting “RAG is dead.”
The truth? RAG isn’t dead. It’s missing a firewall.

The WFGY Approach: A Semantic Firewall

WFGY doesn’t replace your infra or retrain your model.
Instead, it acts like a semantic firewall:

Catches drift before it spreads
Injects mathematical operators as guardrails
Repairs collapsed reasoning chains on the fly

Think of it as: AI is a rocket, but the tools we’re given are bicycles. WFGY is the missing stage in between.

Results You Can See

Numbers are one thing — I’ll give you both.

Benchmarks (WFGY 2.0):
· Semantic accuracy +40%
· Reasoning success +52%
· Drift reduced −65%
· Stability horizon +1.8×
· Self-repair rate: perfect 1.00

Visual “eye test” benchmark:
I attached WFGY to text-to-image prompts like:
“Merge all iconic scenes from Romance of the Three Kingdoms into a single 1:1 artwork.”

Without WFGY → characters collapse, logic drifts, artifacts appear.
With WFGY → stable composition, fidelity to source text, no drift.

You don’t need AI evals to see the difference.

Open Source as My Growth Engine

GitHub is brutal: 95% of repos never cross 100 stars.
Yet WFGY grew to 600 in 60 days. Why?

I targeted real “pain users” (people struggling with RAG bugs).
Every star is public, verifiable. (Even the Tesseract.js author starred the repo — I’ll always brag about that 🌟).
I treated open source not as “free stuff” but as a global trust-building weapon.

💡 My lesson:

The market doesn’t reward features that meet needs. It rewards weapons that kill pain.

Where I’m Going

Phase 1 (solo “ice-cold start”) is done.
Phase 2 is team and scale.

I’m still just one person, but the math is solid and the market is massive. RAG alone is projected to grow from \$1.5B in 2024 → \$10B+ by 2030.

So the question is simple:
Who wants to help me build the reasoning firewall for AI?

✍️ PS: If you’re curious, you can grab the WFGY core pack, upload it to your favorite AI, and literally ask:
“Explain what this does and how to use it.”
Yes — even the AI can onboard you.
