In May 2026, Claude Code's Hooks system received a significant upgrade. PostToolUse hooks can now intercept and replace output from any tool (not just MCP), hooks can read the current effort level via effort.level or $CLAUDE_EFFORT, and duration_ms tracks actual tool execution time. A new claude ultrareview subcommand also enables non-interactive code review from CI pipelines.
In May 2026, Anthropic shipped Claude Code with Opus 4.7 as the default model, plus /ultrareview for parallel multi-agent code review and Routines for event-driven cloud agents. AI coding tools are crossing a threshold β from assistants to autonomous teammates.
Claude Code Routines, launched in April 2026 as a research preview, runs AI agents on Anthropic cloud infrastructure using three triggers: scheduled, API, and GitHub events. Available on Pro plans ($20/month) and above β the agent keeps working even when your laptop is closed. A practical setup guide and real-world education and business scenarios.
OpenClaw is an open-source AI agent platform that connects Claude, GPT, and DeepSeek to 20+ messaging platforms including Telegram, Slack, and WhatsApp. April 2026 updates brought a Claude CLI MCP bridge and major streaming improvements. Here is what it means to run your own AI assistant.
Anthropic massively upgraded Claude Code in March 2026. With Voice Mode, /loop scheduled tasks, and Computer Use, Claude Code has evolved from a coding assistant into a full autonomous agent environment.
