🔬 New AI Craft
1. Anthropic Open-Sources defending-code-reference-harness for AI-Powered Vulnerability Discovery
Anthropic released an open-source framework for AI-driven security vulnerability discovery. Unlike conventional AI code review (style/quality checks), this focuses on proactively finding security flaws — a complementary layer for your CI pipeline's security audit stage.

2. Anthropic Publishes Progress on Recursive Self-Improvement
Official blog details how AI systems can improve themselves — seen as a key path to capability jumps. Same day, Anthropic called for a global pause on AI development, warning about risks of uncontrolled self-improvement.

3. smallcode: 4B Active-Parameter Coding Agent Hits 87% Benchmark
A coding agent optimized for small LLMs, achieving 87% on SWE-bench with only 4B active parameters. Lightweight enough for local deployment and low-latency agent workflows.

4. Alibaba Open-Sources Open Code Review — AI Code Review CLI
A lightweight CLI tool for AI-powered code review that plugs directly into existing Git workflows. Designed for pre-commit CI pipeline integration rather than a full platform approach.

5. forkd: Fork Primitive for AI Agent MicroVMs
Spawn 100 agent microVM instances from a warm parent in ~100ms with KVM isolation. 1-2 orders of magnitude faster than container-based approaches for大规模 parallel agent workloads (batch code review, parallel testing).
