Anthropic Just Killed Tool Calling

Description

Anthropic's latest Sonnet 4.6 release quietly introduced programmatic tool calling; a feature that lets AI agents write code instead of JSON to invoke tools, slashing token usage by up to 98% while improving accuracy. I break down why this "code mode" approach outperforms traditional tool calling, how companies like Cloudflare and Anthropic are already implementing it, and why this could become the new industry standard just like MCP did. If you're building AI agents, this might be the most important under-the-radar upgrade of the year. https://platform.claude.com/docs/en/agents-and-tools/tool-use/programmatic-tool-calling https://www.anthropic.com/engineering/effective-context-engineering-for-ai-agents https://claude.com/blog/improved-web-search-with-dynamic-filtering https://www.anthropic.com/news/model-context-protocol https://platform.claude.com/docs/en/agents-and-tools/agent-skills/overview https://claude.com/blog/equipping-agents-for-the-real-world-with-agent-skills https://www.anthropic.com/engineering/advanced-tool-use My Dictation App: www.whryte.com Website: https://engineerprompt.ai/ RAG Beyond Basics Course: https://prompt-s-site.thinkific.com/courses/rag Signup for Newsletter, localgpt: https://tally.so/r/3y9bb0 Let's Connect: 🦾 Discord: https://discord.com/invite/t4eYQRUcXB ☕ Buy me a Coffee: https://ko-fi.com/promptengineering |🔴 Patreon: https://www.patreon.com/PromptEngineering 💼Consulting: https://calendly.com/engineerprompt/consulting-call 📧 Business Contact: engineerprompt@gmail.com Become Member: http://tinyurl.com/y5h28s6h 💻 Pre-configured localGPT VM: https://bit.ly/localGPT (use Code: PromptEngineering for 50% off).
