Why your agent RBAC is broken (and how to stop webchat from getting exec)

Last week, we saw a pattern that should make every team shipping AI agents a little nervous: A low-privilege webchat identity asked a backend agent to do something “just this once,” and somehow that request ended up running with elevated exec permissions. No jailbreak. No exotic zero-day. Just a boring, familiar auth bug: the system checked who executed the action, not who originally asked for ...

MemLayer vs Mem0 vs Zep: Choosing the Right Memory System for Your AI Agents

Your AI agent in session 50 should be better than your agent in session 1. But most agents start cold every time — no memory of what worked, what failed, or what the user prefers. The agent memory space has grown fast. Three tools keep showing up in conversations: Mem0, Zep, and MemLayer. They solve the same core problem — persistent context across sessions — but take very different approaches. ...

How I'm Using AI Agents to Find My Next Product Idea

I had no domain expertise, no budget for market research, and no desire to spend months learning an industry manually. So I did what developers do: I built a tool. This is a diary of using AI agents (Ollama + opencode) to automate market research - what worked, what didn't, and what I'm still figuring out. If you're a developer curious about using AI agents for something beyond toy projects—this o...

That's changing. Agents Are No Longer Just Tools — They're Becoming Economic Participants Between late 2025 and early 2026, the role of AI Agents shifted in a subtle but critical w...

I built it out of frustration with the current Windows options, which felt unreliable, with ads, sketchy, or locked behind paid versions, so I made a version for myself and decided to open source it. I'm calling it Onyx.

How I Track AI Token Usage Across OpenAI, Claude, and Cursor Without Opening a Dashboard

I've been thinking a lot lately about how quietly AI tools have become essential to my development workflow. Between ChatGPT for brainstorming, Claude for deep code reviews, Copilot in VS Code, and Cursor as my daily editor, I'm basically swimming in AI-powered features. But here's the thing that kept me up at night: I had no idea what I was actually spending. Every few weeks, I'd get that moment...
