Agent orchestration: why n8n and Camunda solve different problems

This article compares agent workflow orchestration platforms and explains why the ‘simple’ tool often costs more in governance gaps than it saves in setup time.

AI agent state machines: designing persistent workflows

State machine patterns give production AI agents the structure to handle multi-step workflows, recover from failures, and maintain context — here’s the architecture that makes it work.

Agent simulation: WebArena-Infinity and virtual testing

The shift from hand-crafted benchmarks to auto-generated simulation environments is collapsing the cost of agent evaluation — and exposing how far even the strongest models still lag behind humans.

Security guardrails for autonomous AI agent systems — OWASP ASI framework

OWASP Top 10 for agentic apps: agent security guardrails

Autonomous agents introduce attack surfaces traditional security never anticipated — and the new OWASP ASI framework is the first standard built to address them.

Browser Automation Agents: OpenAI's CUA and GUI-Based AI

OpenAI’s Computer-Using Agent (CUA) navigates any website by seeing and reasoning — no DOM, no selectors. This deep dive covers how CUA works, how it compares to Anthropic’s approach and traditional RPA, and where the technology still falls short.
