Everyone Shipped Agent Isolation. Nobody Agreed on What From.
Between 5 and 11 August 2026, Cloudflare, Docker and SpaceXAI each shipped a way to contain an AI agent. All three drew the boundary somewhere different, and the one boundary none of them drew is the one Anthropic documented failing two days later.
MCP Went Stateless and Left the Tool Descriptions Alone
The largest MCP revision since launch rewrote the transport and hardened authorization. It says nothing about sanitizing tool descriptions, nothing about a trust boundary around tool metadata, and nothing about provenance. That is a choice worth naming.
Cost Per Finished Task
Bun's Rust rewrite cost 165,000 dollars in tokens and shipped. Uber caps each engineer at 1,500 dollars a month. The per-token price is now the least interesting number in the sentence.
The Best Agent Scores 25.6 Percent
Harbor-Index distilled 82 tasks from 54 benchmarks and the leader passes a quarter of them. Meanwhile the standard way of validating an LLM judge was shown to overstate agreement by 33 to 41 points.
Agentic Search Lost to a Vector Index
On repository code questions, semantic search answered 65.2 percent correctly against 46.2 for a planner-and-subagent system, at less than half the cost. The largest failure category was the handoff itself.
MCP Went Stateless: What Breaks in 2026-07-28
The largest MCP revision since launch removes the initialize handshake and the session header, deprecates Roots, Sampling and Logging, and replaces server-initiated calls with a retry. Here is the actual list, and what it costs to migrate.
Start Here - Building an AI System
Why I'm building a full AI system in public, piece by piece - and how to follow along (and deploy it yourself).
Custom Instructions
Shaping how the system behaves and stays on task.
Multi-Client Wireup - ChatGPT, Claude Code, Grok, Copilot
One server, every client - connecting the same MCP to the tools you already use.

What an AI Agent Actually Is
Everyone says 'agent' like it's magic. It isn't; it's a loop. Here's the whole idea in plain English.
Tokens and the Context Window
What the model actually sees; and why it seems to forget things mid-conversation.
Embeddings: How a Computer Gets Meaning
How words and ideas become numbers a machine can actually compare.
RAG in Plain English
Retrieve-then-generate; what it is, and when it beats fine-tuning.

How a text-only model reaches out and acts on the real world.
MCP, Explained
One plug for every tool; why everyone is suddenly shipping an MCP server.
What an Eval Is
How you measure an AI system before shipping it, so 'is it better?' stops being a vibe.
The True Cost of One LLM Call
Tokens, latency, and dollars; the real math behind a single call.
