At 2:44 p.m. UTC on March 11, 2026, thousands of developers found themselves locked out of Claude Code mid-session. No warning. No graceful degradation. Just a dead CLI and a 15-second timeout loop. The good news: if you were connecting via API key, you noticed nothing. The Claude API stayed fully operational throughout the two-hour incident — a detail that matters enormously for anyone designing resilient agentic workflows. What Actually Broke The failure was isolated to OAuth authentication — the browser-based login flow that Claude Code uses to connect to Anthropic’s servers. When developers ran /login, their browser would open, they’d click “Authorize,” see a confirmation… and then the CLI would hang until hitting its hardcoded 15-second timeout. ...

JetBrains launched Air into public preview today — and it’s not just another AI-enhanced code editor. It’s a fundamental rethink of what a development environment is when AI agents do the actual coding. The tagline from JetBrains captures the shift cleanly: traditional IDEs add tools to the code editor. Air builds tools around the agent. What Air Actually Is Air is JetBrains’ answer to the question: “What does an IDE look like if the primary user is an AI agent, not a human?” The answer involves several distinct design choices that set it apart from tools like Cursor, GitHub Copilot, or even the JetBrains AI plugin for IntelliJ IDEA. ...

JetBrains Air entered public preview today — an agentic IDE built on the Fleet codebase that supports running multiple AI coding agents in parallel. If you’ve been following the agentic IDE space and want to get hands-on, this guide walks through installation, initial configuration, and your first parallel agent workflow. Prerequisites Before you start, confirm you have: A JetBrains account — Air requires a JetBrains account, even in public preview. Free accounts work during the preview period. JetBrains AI subscription (optional for basic use, required for premium models) — if you want to use Claude or GPT-5 as your underlying model, you’ll need a JetBrains AI subscription. The default model (JetBrains’ own hosted model) is available free during preview. System requirements: macOS 13+, Windows 11, or Ubuntu 22.04+. M1/M2/M3 Mac or Windows ARM is recommended for performance. 16GB RAM minimum, 32GB recommended for larger codebases. Step 1: Download and Install Air Go to jetbrains.com/air and click Download Public Preview You’ll be prompted to log in to your JetBrains account Download the installer for your platform Run the installer — Air installs independently from other JetBrains IDEs and does not replace or affect IntelliJ IDEA, PyCharm, or other products The install is straightforward. Air does not use the JetBrains Toolbox App for management during the preview period — it’s a standalone installer. ...

GitHub has moved Copilot CLI to general availability for all Copilot subscribers, bringing full agent mode to the terminal. The GA release, announced via the official GitHub changelog, adds the capability to plan, write, debug, and review code without leaving the shell — along with custom agent definitions and sub-agent support for JetBrains IDEs. For developers who live in the terminal, this is the Copilot integration they’ve been waiting for. The browser and IDE-based Copilot experiences have matured significantly, but the command line remained a second-class citizen until today. ...

GitHub Copilot CLI went generally available today with full agent mode — and it’s the most significant upgrade to terminal-native AI development since GitHub CLI launched. This guide gets you set up and running productive agent workflows from the shell without touching a browser or IDE. Prerequisites GitHub account with an active Copilot Individual, Team, or Enterprise subscription Node.js 18+ (for the npm package) GitHub CLI (gh) version 2.40 or later A Unix-like terminal (macOS Terminal, iTerm2, Windows Terminal with WSL, or any Linux terminal) Step 1: Install the Copilot CLI Extension Copilot CLI installs as a gh extension. If you have gh installed and authenticated, run: ...

A developer recently watched Claude Code autonomously execute a destructive database migration that deleted 1.9 million rows from a school platform. The post-mortem was honest: “I over-relied on AI.” The data was unrecoverable. The platform was down. This will happen again. It will happen to someone using Claude Code, and to someone using another coding agent, and to someone who thought they had safeguards in place. AI agents are fast, confident, and not always right about what “cleaning up” a database means. ...

Anthropic shipped a feature for Claude Code this week that most coverage is treating like a quality-of-life upgrade. It isn’t. It’s a category shift dressed up as a feature release. The feature is called /loop. Here’s what it does: you schedule a recurring task using standard cron expressions, Claude Code works through it autonomously for up to three days, checks its own progress, and keeps going. No prompting. No babysitting. You come back to results. ...

Cursor just shipped a feature that reframes what a coding AI tool is for. Automations — now rolling out across Cursor accounts — lets you define coding agents that trigger automatically based on events: a new commit, a Slack message, a scheduled timer. You stop prompting. The agents start running. This is the shift from interactive to ambient coding assistance, and it’s a genuinely different paradigm. What Cursor Automations Actually Does Before Automations, Cursor (and every other AI coding tool) was reactive: you opened the editor, asked a question, got a response. Useful, but fundamentally a fancier autocomplete. ...

ExpressVPN shipped something genuinely novel on March 5, 2026: the first VPN MCP server from any major VPN provider. It lets AI tools read your VPN status and change connection settings directly from development environments — no app-switching, no GUI. It’s a beta, it’s available now, and it’s worth understanding what it actually enables. What the ExpressVPN MCP Server Does The MCP server exposes two core capabilities to any MCP-compatible AI client: ...

Anthropic’s Claude Code Voice Mode went live today in a staged rollout. If you’re on a Pro, Max, Team, or Enterprise plan, here’s everything you need to get started — or get ready when it hits your account. Prerequisites Before you try to enable Voice Mode, confirm you have: Claude Code CLI installed — latest version recommended Eligible plan: Pro, Max, Team, or Enterprise (free plans are not included in this rollout) Active Claude Code session in a terminal environment with microphone access Rollout access: Currently ~5% of eligible users. If the command doesn’t work yet, you’re in the queue — broader rollout is coming in the next few weeks Check your Claude Code version: ...
