Why Your API Workflow Is Broken (And How to Fix It With Plain Text)

You know that moment when you're onboarding onto a new project, someone says "the API collection is in Postman," and your heart sinks a little? You need to create an account, sync a workspace, hope you have the right permissions, and pray that whoever wrote those requests actually kept them updated. I've been there more times than I can count. And after watching three different teams struggle wit...

How I Packaged 130+ Hours of AWS Infrastructure Into Reusable Templates

Every new project starts the same way. You spin up an AWS account. You need a VPC. Three AZs, public and private subnets, NAT Gateways. Then you need security — CloudTrail, GuardDuty, IAM hardening. Then CI/CD pipelines. Then Terraform modules. Then Docker Compose for local dev. Then Nginx for production. Each time, you either copy-paste from your last project (hoping nothing broke) or build fro...

Coding Cat Oran Ep4, Speaking Human

The boss called a company-wide meeting. Twenty minutes, conference room, Friday 2pm. "Oran, you'll present the new system. Show everyone how it works." Oran had three days to prepare. He felt ready. He'd rebuilt the permission layer, redesigned the inventory module, added the approval workflow. The system was solid. He made a slide deck. Fifteen slides. Entity-relationship diagrams.

Anthropic says MCP command execution is expected behavior — here is how to test what that means for your agent

OX Security spent five months investigating Anthropic's Model Context Protocol. They filed 10 CVEs across the MCP ecosystem. Anthropic's response: this is how STDIO MCP servers are designed to work. They're right. And that's the problem. What "expected behavior" means MCP's STDIO transport takes a command string and passes it to OS subprocess execution. The subprocess runs before the ...

You keep rewriting the prompt. Upgrading the model. Adding more instructions. The agent still gets it wrong. After hundreds of failed traces, I found where the failures actually live. Everyone in AI is waiting for the next model drop. GPT-5 will fix it. Claude 4 will fix it. Gemini Ultra Pro Max will definitely fix it this time. I've been building production AI agents for three years. Not weeken...

We Analyzed 4,584 MCP Servers — The Average Trust Score Is 53.9 Out of 100

The Model Context Protocol (MCP) ecosystem is growing fast. Thousands of servers now expose tools that AI agents can call — calculators, databases, search engines, compliance checkers, weather APIs, and more. But here's the problem nobody's talking about: how do you know which servers you can actually trust? Static code scans and self-reported badges tell you what a server claims to be. They don...
