AI Coding Tools Week 14: New Critic Agent & Major Interface Overhaul

# AI Coding Tools Week 14: New Critic Agent & Major Interface Overhaul ## TL;DR 📋 - **New AI critic agent** automatically reviews your code plans and catches errors before you ship - **Cursor 3.0** drops with completely redesigned interface ## This Week's Releases ### Claude Code (5 releases) Claude's been busy with policy updates and interactive features. The standout addition is a `forceRemoteSettingsRefresh` policy that blocks CLI startup until settings are fetched - useful for enterprise environments that need fail-closed behavior. ### Undefined Tool (6 releases) Major week for this mystery tool with **6 rapid-fire releases**. The headline feature: a new Critic agent that automatically reviews your plans and complex implementations using a complementary model. It's in experimental mode for Claude models, but early reports suggest it catches logic errors you'd miss. Also shipped: built-in CLI skills and HTTPS redirect support for MCP OAuth flows. ### Cursor (1 release) Big news: **Cursor 3.0** landed with a completely new interface. No detailed changelog yet, but expect the usual Cursor polish with better code completion workflows. ### Gemini CLI (1 release) Version 0.36.0 introduces multi-registry architecture and tool filtering for subagents. This looks like foundational work for more complex agent orchestration. ### OpenAI Codex CLI (1 release) Windows users get better sandbox security with OS-level egress rules instead of just environment variables. Plus new app-server client capabilities. ## Highlight Deep Dive 🔍 The **Critic agent** from the undefined tool is potentially game-changing for solo developers. Instead of just generating code, it automatically reviews your implementation plans using a separate model to catch logical flaws, edge cases, and architectural issues. Think of it as having a senior developer constantly peer-reviewing your work. While still experimental, this could significantly reduce bugs that make it to production - especial
