Junie CLI Now Connects to Your JetBrains IDE
Junie CLI now connects directly to your JetBrains IDE, using its semantic index, test runners, and build configs. No more guessing at project structure or breaking tests. Here's what changes for complex codebases.
GitHub Copilot CLI's Rubber Duck Uses Cross-Model Review
GitHub Copilot CLI's new Rubber Duck feature uses a second AI model family to review agent plans and code. Claude Sonnet + GPT-5.4 closes 74.7% of the performance gap to Opus on difficult multi-file tasks.
Claude Code Gets Sandboxing: 84% Fewer Permission Prompts
Anthropic added OS-level sandboxing to Claude Code, cutting permission prompts by 84% while blocking prompt injection attacks. The sandbox runtime is open source, and Claude Code now runs securely in the cloud.
Code Execution with MCP: Why Your AI Agent Is Wasting Tokens
Loading thousands of MCP tool definitions upfront burns 150,000+ tokens before your agent starts working. Code execution cuts that by 98.7% by loading tools on-demand and processing data locally. Here's how it works.
Anthropic Just Fixed the Three Biggest Problems With AI Tool Use
Anthropic shipped Tool Search Tool, Programmatic Tool Calling, and Tool Use Examples — three features that cut token overhead by 85%, eliminate inference passes on intermediate results, and teach correct API usage through examples instead of schemas.
