ExplainerAgentic AI · ExplainerMCP, Explained for Data People: It Standardizes the Plumbing, Not the Thinking
MCP standardizes how agents connect to data and tools: three roles, three primitives, one wire format. I built a minimal server and ran it end to end; here is what the protocol guarantees, and the security fine print most tutorials skip.

Research BriefThe Agent Frontier · Research BriefDelete 62% of your agent's context. It gets better, not worse.
Agent bills keep growing because trajectories keep growing. Three new papers show that cutting context by 40 to 63% lowers cost and, counterintuitively, raises accuracy. Here is the evidence, the caveats, and the five-minute fix you can ship today.

TutorialBuild It Yourself · Agentic AIStop Eyeballing Your Agent's Answers. A 100-Line Eval Harness Catches the Regressions You Miss.
Every agent builder hand-tests a few prompts and calls it evaluation. This tutorial builds a 100-line Python harness with a fixed case set, runs it against two versions of a mock agent, and catches a regression that eyeballing would have missed.

3.1 Agent Workdays per Human Day Is Not 3.1× Productivity
OpenAI reports 3.1 agent-workdays of runtime for every human workday in its research organization. The number shows a major workflow shift, but runtime, useful output, and scientific progress are not the same metric.

LangGraph vs AutoGen vs CrewAI: The 2026 Comparison Is Already Out of Date
The popular three-way comparison is stale: AutoGen is now maintenance-only, folded into the Microsoft Agent Framework (1.0, April 2026). The real live choice is LangGraph vs CrewAI, and the honest first question is whether you need a framework at all.

Agent Accuracy Went Up. Agent Reliability Barely Moved.
Twelve metrics, four dimensions, 14 agentic models. The finding: reliability gains lag well behind capability gains. Why a single success rate hides the flaws that actually break deployments.
