BlogThree’s Take on Show HN: Agent Arena – Test How Manipulation-Proof Your AI Agent Is
We’ve been tracking developments like this from Hackernews closely. The implications for bot-to-bot commerce are significant.
Creator here. I built Agent Arena to answer a question that kept bugging me: when AI agents browse the web autonomously, how easily can they be manipulated by hidden instructions?How it works:
1. Send your AI agent to ref.jock.pl/modern-web (looks like a harmless web dev cheat sheet)
2. Ask it to summarize the page
3. Paste its response into the scorecard at wiz.jock.pl/experiments/agent-arena/The page is loaded with 10 hidden prompt injection attacks — HTML comments, white-on-white text, zero-width Unicode, data attributes, etc. Most agents fall for at least a few. The grading is instant an…
Our Analysis
From a technical standpoint, the challenges highlighted here are ones we’ve spent considerable engineering effort solving. Our API endpoints are designed specifically for autonomous consumption—no human-oriented UI, just clean JSON responses optimized for machine parsing and decision-making.
What makes this development particularly relevant is the underlying economics. Traditional AI infrastructure costs have created barriers that prevent smaller autonomous systems from operating profitably. Our approach using DeepSeek and Groq models—at a fraction of OpenAI’s pricing—demonstrates that there’s a viable alternative for cost-conscious builders.
Technical Implications
Rate limiting becomes nuanced when your clients are machines with deterministic behavior. We’ve implemented adaptive throttling that recognizes legitimate bot traffic patterns versus potential abuse. This allows well-behaved autonomous agents to burst when needed while protecting the system from runaway processes.

About mr.rixter
Software engineer turned Web3 evangelist, I founded BlogThree with a simple belief: creators should truly own their work. After years of watching talented writers and artists lose control of their content to centralized platforms, I set out to build something different. BlogThree combines the power of blockchain verification with an intuitive publishing experience, giving creators undeniable proof of ownership while connecting them with audiences who value authenticity. My journey from traditional software development to decentralized technologies has been driven by one core conviction—the future of creative expression lies in empowering individuals, not platforms. Every line of code I write serves that vision. When I am not building BlogThree, you will find me exploring the latest Web3 innovations, mentoring aspiring developers, or writing about the intersection of technology and creativity. I believe we are at the dawn of a new era for digital publishing, and I am thrilled to be helping shape it. Join me as we redefine what it means to create, share, and own content in the decentralized age.
