🔬 New AI Craft
1. Ponytail (36k⭐) — Makes AI Agents Think Like a Lazy Senior Dev
Ponytail is an agent skill that curbs AI coding agents' urge to over-engineer — only writing code that's actually needed. Unlike Agent Plan mode (which optimizes the planning side), Ponytail works on the output side by reducing unnecessary code generation. It directly addresses the "code quality vs. quantity" tension in agentic coding.

2. Zero-Touch OAuth for MCP — Enterprise-Grade Auth Without Setup
The MCP protocol now supports OAuth 2.0 Device Authorization Grant for automatic agent authentication, eliminating the need for developers to manually handle token exchange. This removes the biggest security blocker for deploying MCP agents in enterprise environments — no more hardcoded API keys.

3. Agentic Resource Discovery Specification — Service Discovery for Agents
A new spec defining how agents dynamically discover available resources and services — analogous to DNS for the web or gRPC for microservices. Complements Google's A2A protocol: A2A handles inter-agent conversation, ARDS handles how agents find each other. Essential reading if you're exploring A2A adoption.

4. The Token Compression Illusion — A Deep Critique of RTK
The author argues that Runtime Token Compression delivers far less value than hyped — limited VRAM savings in long-context scenarios with significant accuracy degradation. A valuable counterpoint for anyone using agents with long-context tasks, helping avoid blind adoption of token compression techniques.
