The Agentic Engineer

• LangChain open-sources Deep Agents. MIT-licensed coding agent built on LangGraph. Works with any model. Planning, filesystem, shell, sub-agents out of the box. pip install deepagents and you have a Claude Code alternative for $0.

• A GitHub issue title compromised 4,000 developer machines. The first documented "AI installs AI" supply chain attack. Prompt injection in Cline's triage bot led to credential theft and malicious npm publishes.
