The feature enables developers to initiate planning jobs from the terminal while the planning executes in the browser, supporting inline comments, emoji reactions, and revision requests on individual plan sections.

GitHub has added a feature called Rubber Duck to Copilot CLI that queries multiple AI model families to provide alternative perspectives on code suggestions. The feature acts as a second opinion mechanism, allowing developers to compare recommendations from different model architectures.

Cursor released version 3 of its AI coding tool with a complete interface redesign built around running multiple AI agents in parallel rather than individual code editing. The new "agent-first" interface allows developers to launch agents from desktop, mobile, web, Slack, GitHub, and Linear, with seamless switching between cloud and local environments.

GitHub's Applied Science team deployed coding agents to automate parts of their own development workflow, testing how AI agents can handle increasingly complex programming tasks. The experiment reveals practical insights into agent-driven development patterns and limitations.

OpenAI released a plugin that embeds its Codex coding assistant directly into Anthropic's Claude Code, the market-dominant code IDE. The plugin offers standard code review, adversarial review, and background task handoff capabilities, requiring only a ChatGPT subscription or OpenAI API key.

OpenAI is releasing a set of open-source prompts developers can use to make their applications safer for teens. The policies, designed to work with OpenAI's gpt-oss-safeguard model, address graphic violence, sexual content, harmful body ideals, dangerous activities, and age-restricted goods.

Anthropic has released 'auto mode' for Claude Code, a permissions system that sits between conservative defaults and fully disabled safeguards. The feature uses a classifier to automatically approve safe actions like file writes and bash commands while blocking potentially destructive operations.

Anthropic has added "channels" to Claude Code, enabling Claude to respond to incoming messages, webhooks, and notifications asynchronously without user intervention. The research preview supports Telegram and Discord with custom channel support, running through MCP servers with two-way communication.

OpenAI has acquired Astral, the company behind widely-used Python development tools Ruff, uv, and ty, which see hundreds of millions of downloads monthly. The tools will integrate with OpenAI's Codex platform to enable agentic AI systems that can plan changes, modify codebases, run tools, and verify results. OpenAI commits to keeping the tools open source under permissive licenses post-acquisition.

Google Deepmind has expanded the Gemini API to enable multi-tool chaining, allowing developers to combine built-in tools like Google Search and Google Maps with custom functions in a single request. Results from one tool now automatically pass to the next through context circulation, eliminating the need for separate sequential handling.
