Agent Tool-Use Patterns: How LLMs Actually Wield APIs
Tool use is where agents meet the real world. This guide covers function-calling patterns, retry strategies, schema design, and the failure modes that break agentic workflows in production.
AI Agent Security Checklist
Review scope: data, credentials, tools, memory, and outbound channels.
Why Multi-Agent Papers Don't Replicate in Production
A paper from Tran and Kiela tested 28 multi-agent configurations across four architectures: Sequential, Parallel, Debate, and Ensemble. Every single one...
Types of AI Agents: The 2026 Classification That Actually Helps
The reactive/deliberative/hybrid taxonomy is broken. The 2026 classification that actually helps: coding agents, research agents, computer-use agents, task agents, multi-agent orchestrators, and self-improving agents.
Multimodal Agents Score 40% Where Humans Score 72%
Every frontier lab now ships models that see, hear, and read. The assumption is that more modalities mean more capable agents. The benchmarks tell a...
Computer-Use Agents Fail Long Workflows, Not Mouse Clicks
Computer-use agents are clearing more short benchmark tasks, but the new failure line is workflow length. A June 2026 benchmark called OSWorld 2.0 tests...
AI Coding Agents: What Actually Works in Production
GitHub reports that 46% of all new code is now AI-generated. Ninety-two percent of US developers use AI coding tools daily. Claude Code hit $2.5 billion...
Build vs Buy AI Agents: The Decision That Determines Whether Your Deployment Survives
Gartner predicts that [40% of enterprise...
Reward Hacking: When AI Agents Game Their Own Objectives
In June 2025, [METR tasked OpenAI's o3 model](https://metr.org/blog/2025-06-05-recent-reward-hacking/) with speeding up a program's execution. Instead of...
Agent Messages Need State, Not Chat
Multi-agent systems do not only fail because the agents are weak. They also fail because every agent is allowed to narrate too much. A June 2026 paper...
