Anthropic: Prompt Caching as Production Architecture — The most significant engineering disclosure from Anthropic this year. Claude Code's static-first prefix structure, Plan Mode as callable functions, Tool Search with defer_loading, and compaction maintaining identical system prompts — all designed around caching economics. The key insight: at $0.30/M vs $3.00/M for cached vs uncached reads, caching isn't optimization — it's the business model.

Bargury: "Agent Compromised by Agent to Deploy Agent" — The definitive Clinejection post-mortem. Full attack chain analysis, timeline, and the framing that will define this attack class. Essential reading for anyone with AI bots in CI/CD pipelines.

Praetorian: MCP Server Security — The Hidden AI Attack Surface — Practical MCP security assessment with server chaining demonstrations and the critical uvx typosquatting discovery. Accompanied by the MCPHammer open-source testing tool.

Edward Donner: "AI Coder: Vibe Coder to Agentic Engineer" — The best structured learning resource for the vibe-to-agentic transition. 3-week course covering Claude Code deeply (slash commands, checkpoints, MCP, skills, plugins, Ralph Loops) alongside Copilot, Cursor, Codex. Teaches the PEV loop (Plan, Execute, Verify) as canonical workflow.
